If your air conditioner is going to have a refrigerant leak, there’s a good chance it will happen on the indoor coil.
Also known as the evaporator coil, this air conditioner component lives inside your HVAC system’s indoor unit. Refrigerant passes through it. Air passes over it. Heat is removed from your home, and you feel great all through August.
Until it starts to leak.
When you’ve got an indoor coil that’s leaking refrigerant, it will take a long time for the system to cool your home… if it cools your home at all. Even if your AC doesn’t quit right away, you’ll experience longer run times.
As the leak worsens, the system will lose its ability to cool.
Sadly, repair isn’t an option.
There’s no reliable way to repair the leaks themselves. Evaporator coils are large components that reside in dark places and are characterized by tiny dips, curves, crevices, and hard-to-see, hard-to-reach areas. When it comes to finding leaks, the needle-in-a-haystack analogy applies.
And keep in mind that you might be dealing with several little leaks, not just one big obvious one.
For this reason, you’ll usually have to replace your coil, your air handler, or your entire HVAC system. It all depends on what kind of system you’ve got, how old it is, and your long-term priorities for heating and cooling.
Sometimes, replacing a leaky evaporator coil is your best choice. Other times, you should replace your air handler or even your entire system.
Your decision depends on what type of system you’ve got today and the level of comfort and efficiency you’d like to enjoy in the future.
And if you’re reading this article breathing a sigh of relief that you’ve never had a leaky evaporator coil, know this: It can happen to you. That doesn’t mean it’ll happen this summer, next summer, or the summer after that. But it’s always possible.
Now that you know what to do, you can make a confident decision that resolves the problem as quickly as possible.

As the seasons change and the Massachusetts weather gets hotter, the time to start up your AC unit is approaching fast. Many people run into snags when first starting up their AC units and wind up calling Vasi Refrigeration, a local furnace and air conditioning company for cooling system repair. But we’ve found that the most common of these problems have simple solutions that doesn’t always require professional repair services. With that in mind, we’ve provided some quick troubleshooting tips for the first of the year air conditioning start-up and detailed guide that will help you make this year’s start-up go smoothly. Vasi is available by appointment if you would rather have a professional take care of the startup for you.
Air conditioning start-up guide and troubleshooting tips:
Change the filter.
The most common problem in AC unit start-up is a dirty filter. The filter is located in the furnace, and when it’s dirty, it will make your system freeze up when you try to start it up. To avoid this, clean or replace your filter before attempting to start up the AC unit. If, however, you discover a dirty filter after turning the unit on, simply turn it off, clean the filter, and wait two hours before turning it back on. Changing the filter in the furnace is the biggest thing you can do to avoid needing professional repair services.
Turn you AC unit on.
Using your manufacturer directions to turn the power on your air conditioning unit.
If you still have problems starting up your AC unit, check the breaker box in your house to ensure that the breaker for the AC has not been flipped off. Then check the gray metal box next to the unit to make sure the breaker there has also not been flipped. The unit’s box will either have a normal breaker or a tab you have to pull out, flip over, and put back in.
Check that all vents are open, return air registers are clean and unblocked in your home when the fan starts blowing. This will alert you if a duct is blocked and will help ensure each room will be cooled appropriately
Ensure good air flow.
You may also experience problems with start-up if small objects (like grass, dirt, or cottonwood fluff) get lodged in your AC unit. To clean these out, turn the unit off and use a standard garden hose to spray the coil at a downward angle. It is important not to use a high-pressure sprayer, as that can damage the unit.
Check that the power to the Furnace is ON.
If you have checked all of these items and your Furnace or AC is still not working properly, please give Vasi a call at (781) 526-1637.
We hope that this short AC repair troubleshooting guide will help you save money this year. Keep in mind, however, that many air conditioning problems will require professional assistance. If you notice that your central air unit is not working efficiently—running all the time regardless of how hot it is or blowing only hot or warm air—then give us a call at (781) 526-1637 to discuss repair costs or contact us online.
DIY heat pump maintenance versus professional help.
It seemed that winter would last forever, but spring is finally upon us. As the weather warms and you use your heat pump less, it’s a good time to run maintenance so it doesn’t sit through the spring with dirty or failing components. Don’t wait to discover a problem in the heat of summer or the cold of the next winter when you need that heat pump working!
Many people forget that their heat pumps require regular maintenance to keep them at their peak performance levels. But with the right upkeep, these units can work trouble free for years and years to come. Although some you can do many maintenance steps yourself, other things may require a professional. Whether done by a professional or yourself, your heat pump needs the following steps to keep it going strong.
Do It Yourself Heat Pump Maintenance
These heat pump maintenance items are easy. Almost anyone can handle these without professional help:
– Change your air filters. You can do this every month or every 6 months. It just depends on how quickly your air filters get dirty. Many factors come into play when deciding how often to change the filters, such as allergies, pets, and the level of traffic and air pollution around your home. A dirty filter makes your heat pump work harder and your electric bill go up. You can usually tell if you’ve waited too long to change the filter when you see above average dust accumulation on surfaces in your home.
– Give it room to breathe. Keep debris from collecting around the outside unit. Don’t let grass grow into any part of the unit where it can choke off moving parts, such as fans or restrict airflow. You should cut your grass or shrubbery back for at least a foot of clearance around the unit. In addition, keep toys, yard decorations or outdoor furniture from collecting around the unit. Your heat pump needs to breathe.
– Clean the coils. You should clean the coils and fans that are within easy access. Again, the timeline depends on how quickly they get dirty, but do this every spring, at least.
– Keep vents open. Do not block vents within your home. Keep furniture, toys, draperies and other household items clear of any vents in your floor, ceiling or walls.
You’ll need expert to inspect the vents, vent fins, fans, coils, drainage and general overall performance of your heat pump. An expert will check the refrigerant levels, electrical connections and components, the condensate drainage system and blower components. All these things are better left to a professional.
Consider a Service Contract
A service contract takes care of all the DIY maintenance items plus those issues that need a professional’s attention. Otherwise, you can manage simple maintenance yourself and simply call for an annual inspection.

Common Causes for Emergency HVAC Service
Ideally, you don’t want to deal with any kind of heater or AC emergency. Here are some of the top reasons why these systems fail:
Improper Preventive Maintenance – Improper preventive maintenance is the number one reason for emergency calls. Consult your system’s owner’s manual regarding necessary preventive maintenance, including regularly changing filters. You should also schedule an annual professional maintenance visit for tasks such as professionally cleaning and attending to system components and verifying fluid levels. These simple routine tasks are essential to the efficiency, reliability, and safety of your AC system or furnace.
Furnace or RTU – repair or replace
Inexperienced Service – Professional repair is essential for the safety and reliability of heating and cooling equipment. Opt for expert service to prevent the need for inconvenient, costly, and possibly dangerous emergency repair needs caused by inexperienced technicians.
Outdated Systems – Aging heating and cooling systems are far more prone to leave you high and dry than newer, more reliable, and more efficient models. If you are paying for repeated repairs and emergency service calls, consider the 50% rule: When the cost of repairs approaches 50% of the value of your system, you’re typically better off financially in the long run upgrading your system.

You want to finally book that dream trip to Hawaii? now’s as good a time as any! If you want to be better, smarter, cooler, or anything else, you can do it!
Do you know what else you can do? Be a better owner of HVAC systems. We can help. Here are a few HVAC resolutions you can make to prolong the life of your home heating, ventilation, and air conditioning.
Don’t forget to change your filters
You need to change home air filters regularly to best capture home air contaminants. When was the last time you changed your filters? If you can’t remember, it’s probably been too long.
Invest in preventative maintenance
Have a professional plumbing technician come to your home and give everything a thorough once over. Even if you’re fully capable of spotting small problems, getting a second opinion from a pro can help you avoid the trouble even more effectively.
Address any long-avoided duct leaks
Heat loss from duct leaks cause a lot of trouble cost a lot of money. Give your ducts regular visual inspections whenever you’re able, and act as soon as you notice leaks. If you don’t have the right type of metallic foil tape made for duct repairs, that’s ok. You can always call a professional to fix those cracks and save you a few bucks down the line.
Look into eco and wallet-friendly upgrades like a programmable thermostat
Programmable thermostats allow you to directly control the temperature of different rooms inside your home. It lets you make things a little cooler at night when you’re cuddled under sheets. You could even determine the right temp for when you’re out and about from an app on your phone. A programmable thermostat can save you money while simultaneously making your home more comfortable and energy efficient.
Make an effort to be more knowledgeable about your home HVAC
Learning about your HVAC will enable you to more reliably identify and address HVAC problems before they become disastrous. Possessing some understanding of your HVAC helps even if you have no intention of messing with it yourself. It’ll also help make you feel like an enlightened (and awesome, smart, etc.) home owner. Which (you know) is cool too.
Clean your ducts
Getting your ducts cleaned once in a while is a great way to improve the quality of your indoor air. Cleaner indoor air should be one of your priorities for all kinds of reasons. It reduces your risk of airborne illness, prevents mold growth or even pest infestation. It also helps your home smell better.
Connect with the best HVAC maintenance company in your area
When a problem occurs, you don’t want to make an already-stressful situation worse by having to scramble to find someone to call. Prepare ahead of time by checking which local companies have the best reviews, service records, and technicians.
Whatever your resolution is this year, the entire team at Vasi Refrigeration Inc. has your back. If your resolution just-so-happens to be related to HVAC, we double have your back. Never hesitate to give us a call when you need it.

Most garages seem to get a lot use in warm weather, but are often sent into hibernation for the winter. If you would like to spend more time working in your garage in cold weather, here are some affordable heating garage choices worth investigating.

First, Insulate and Weatherize
If you will be using your garage often during the heating season, your energy costs can easily double or triple if your garage has inadequate insulation and weatherstripping. Energy lost through drafty windows or transmitted through uninsulated walls in energy you pay for, so it makes sense to take the same pains with your garage as you do with the rest of your house. In most cases, any money you spend on adding insulating will be paid for in money-savings on energy costs within a few years, according to the Department of Energy. Here are some things to pay particular attention to:
Windows. In a garage that will be heated in winter, make sure the windows have the same insulating value as you would use for your house. Double- or triple-pane insulated glass filled with inert gas is the best choice.
Energy-efficient garage door. Steel, aluminum, or fiberglass doors with polyurethane foam inside will have the best R-values (the resistance to energy loss). For example, 1 3/8-inch-thick polystyrene foam carries an R-value of 6.5, compared to a plain wood door that usually has an R-value of 4 to 5, but polyurethane foam doors have an R-value as high as 20. Most experts suggest that a garage that will be heated should have an overhead door with an R-value of 10 to 12, minimum.
Seals along bottom and sides of the door. Drafts are main source of energy loss, so make sure the weatherstripping along the bottom of the main garage door is in good condition. Also check the weatherstripping on passage doors and windows.
Insulate outside walls. A garage that will be heated and used in winter deserves the same fiberglass batt insulation that is used in your house.
Consider finishing the ceiling. Many garages have open rafters and trusses overhead. Minimize heat loss by insulating the spaces between rafters and trusses and finishing the ceiling with wallboard.
Liquid Fuel and Gas Heaters for Heating Garage
There are a number of space heaters that use liquid fuel, such as kerosene, liquid propane, or natural gas that can be used with caution in a garage. There are two principal types:
Freestanding space heaters burn kerosene or propane are portable and inexpensive, but they are only useful for heating small spaces. Unvented kerosene and propane space heaters can boost the temperature in a small garage, especially if it is insulated, but they also release carbon monoxide and moisture into the air. Be very careful when using a freestanding liquid fuel heater in an enclosed space—many safety experts frown on the practice.
Direct-vent space heaters, on the other hand, can be great choices for supplying heat to the garage, especially if your house is already piped for propane or natural gas that runs your furnace, stove, or a gas fireplace. Direct-vent garage heaters exchange combustion air and exhaust fumes through a pipe in the wall, thereby eliminating carbon monoxide danger. If you plan to use the heater frequently, look for a model with maximum efficiency. Suppliers of direct-vent heaters provide instructions for installing the unit yourself, but even if you feel up to the chore, it’s best to have a professional install the gas line. Direct-vent space heaters are perhaps the best choice for a garage in a cold climate that needs to be frequently heated or kept at a constant above-freezing temperature.
Wood Stoves for Heating Garage
A wood stove can be a great choice for heating the garage under certain circumstances—especially if you have a steady, inexpensive supply of wood for fuel. Using a wood stove comes with caveats, however.
You will need to have room for a safe installation, with proper clearances between the stove and any combustible materials. And all wood stoves must be connected to proper chimneys. A wood stove takes quite a while to heat up and will continue generating heat long after you’ve stopped feeding it fuel, so this is not a good option for short, quick heating needs. A wood stove can be perfect, though, for day-long projects in the garage. A woodworker with lots of scrap lumber on hand might find a wood stove to be a perfect solution.
Caution: Never burn pressure-treated lumber or scraps of sheet material with chemical resins in a wood-burning stove. Burning these materials produces toxic fumes that by law cannot be sent into the atmosphere.
Electric Heaters for Heating Garage
Electric heaters suitable for heating a garage come in many forms, from small 120-volt portable plug-in heaters to 240-volt radiant overhead heating units, to permanent baseboard heaters. The main virtue of electric heaters is their convenience. Electric heaters are quiet, clean, and unobtrusive, they do not require that you tap into a furnace or boiler, and they require no chimneys or vent pipes.
Electric heaters are generally inexpensive to purchase and install, but they can be fairly expensive to operate on a constant basis, especially in very cold climates. In cold climates, it may be best to fully insulate and weatherproof your garage if you want to heat the garage frequently with electric heat. Electric heaters are ideal in more moderate climates where subfreezing temperatures are rare.
Electric space heaters come in three main types:
Convection Heaters – Convection heaters are classic space heaters that warm the air in a room and circulate it due to the natural effects of convection currents that cause warm air to rise and cool air to fall. There are many styles of convection heater, from electric baseboard heaters to portable plug-in radiators that are filled with oil. They are relatively safe heaters to use, especially when equipped with an automatic shut-off feature that kicks in when the heater tips over. Ceramic heaters fall into the convection heater category.
Radiant Heaters – Radiant heaters heat objects in their vicinity, including people, but they don’t specifically heat the air. This is a good choice if you want heat quickly, but they are a bit risky since they can burn people or pets, and pose a fire threat if they are operated too close to flammable materials.
Combination Heaters – Combination heaters combine the virtues of both radiant and convection heaters, by using a fan to distribute the heat produced by radiant coils.
Central HVAC Extension for Heating Garage
It is also possible to extend the system by which your central furnace and air conditioner heats and cools the rest of your house by adding ductwork into a garage that is attached to the house. However, this can dramatically change the load on your HVAC system, so it is best to have professional assess the situation and run the additional ductwork if you choose to go this route. If your furnace has the capacity to serve the garage, this is may be the most effective long-term solution to your heating problem. Make sure, however, that you have taken all measures to insulate and weatherproof your garage.

There’s so much to love about fall – the colorful leaves, the pumpkin spice everything and how HVAC service fights our fall allergens. Truthfully, if you’re one of the many Boston & North Shore’s residents living with allergies, asthma, COPD or other respiratory conditions, HVAC service can improve your indoor air quality. How does regular heating and air maintenance help? Let’s review.
HVAC Service Cleans Your Heating and Air System
When you call a trusted local provider like Vasi Refrigeration to perform HVAC service, a licensed and industry-certified professional visits your home. He is prepared to service any system because of Vasi Refrigeration investment in ongoing training.
Once the technician thoroughly inspects your HVAC equipment, he cleans any dirt, dust or debris from the components. He tests all relevant parts. It’s important to remove dirt and other contaminants from your HVAC system because it hinders air flow. It also finds its way into the mechanical components, shortening their lifespan.
Good air flow is key to comfortable and efficient heating and cooling. Your system performs many duties, depending on the need, such as heat or moisture extraction from the air. If there is dust or debris in the duct-work and components, the system has to push it from room to room too.
Your air filter is the first line of defense for dust, pet dander, pollen and other pollutants. These can clog quickly, depending on household and environment factors. For example, at Vasi Refrigeration, we advise homeowners to check the air filter monthly.
Most people find filters last two to three months. Your system may use a disposable or permanent one. If you have multiple pets or live with allergies, you’ll need to change or clean your filter every one to two months.
When the filter is clogged, it requires more effort from the heating and cooling equipment to function. This strain can, over time, shorten the lifespan of your heating and air system.
HVAC Service Improves Indoor Air Quality
According to the Asthma and Allergy Foundation of America, Boston has improved its standing in the organization’s list of The 100 Most Challenging Places to Live with Allergies. While that’s good news, the Boston area still has many airborne allergens and air pollution. Plus, 90 percent of our lives are spent indoors and indoor air is 3-5 times more polluted than outdoor air.
This fall, Boston fell one place down (80) the list from 2016, based on categories such as pollen score, medicine use per patient and board-certified allergists per patient. When you have a professional clean your heating and cooling system during routine HVAC service, he removes many of the contaminants in your system.
This HVAC service means fewer pollutants circulate throughout your home. If you or a family member live with allergies, asthma or another respiratory or immune-compromised condition, consider whole-home filtration.
Some products significantly decrease the volume of airborne pollutants, such as mold spores, dust mites, bacteria, viruses and other respiratory-triggers.

Furnace Service Is Vital
Regular furnace service and maintenance isn’t the same as repair service. Our furnace inspection and maintenance work will help to ensure safe, efficient operation and help prolong the life of your heating system. Vasi Refrigeration goes well beyond the basics. Our comprehensive precision furnace tune-up includes:
Cleaning the heat exchanger and inspecting for combustion leaks. Heat exchangers can develop cracks with age. If they exist, there’s a risk of serious illness from the potentially toxic fumes emitted.
Performing a combustion efficiency evaluation and test for carbon monoxide. Carbon monoxide is a dangerous odorless gas. Tests are performed to determine if any level of carbon monoxide is being released from the system—this airborne contaminant can have deadly results.
Cleaning burners and adjusting for maximum efficiency. Dirty burners can cause poor combustion, making you pay for useful heat that “goes up the chimney.”
Cleaning pilot assembly and inspecting thermocouple.
A defective thermocouple will cause the furnace to shut down.
Inspecting the flame sensor.
The flame sensor protects your safety by making sure the flame ignites properly.
Examining the flue and inspecting the venting system.
A corroded or leaking flue pipe is dangerous. If they exist, similar to a crack in the heat exchanger, there’s a risk of serious illness from the potentially toxic fumes emitted. A suitable draft or venting system is essential for safe and proper operation of your heating unit.
Verifying proper inducer motor operation.
The inducer removes fumes from your furnace and helps ensure a proper combustion process.
Verifying proper ignition.
The pilot is checked and adjusted as necessary—weak or dirty pilots can be extinguished easily, which causes the furnace to shut down.
Inspecting gas piping and valve.
The combustion air openings are checked— blocked or restricted combustion air openings can be dangerous because they can affect the combustion process and create carbon monoxide. The gas line will be checked for leaks from the furnace shut-off valve to the burners to find any dangerous, undetected gas leaks.
Flushing the condensate drain to protect against overflow.
The condensate drain is checked to ensure it’s open. Overflowing drains can interfere with overall system operation and also cause water damage.
Inspecting blower assembly operation, lubricating and adjusting as necessary.
Motors will last longer with maintenance, and indoor temperatures will remain comfortable with a properly functioning blower assembly. The fan switch is checked and adjusted as needed—a fan switch that isn’t adjusted properly can waste energy, cause nuisance fan cycling and reduce comfort in the home.
Evaluating the condition of the air filter and other indoor air quality accessories.
The air filter and other indoor air quality accessories are evaluated for fit and proper match with your system. Dirty air filters can increase operating costs.
Safety testing all controls for proper operation.
Safety controls that don’t function properly can cause dangerous problems with heating systems. Additionally, controls and safeties that don’t function properly can increase cost of operation and cause other components to fail.
Calibrating the thermostat and confirming proper operation.
Defective or improperly calibrated thermostats affect comfort and operating costs.
Evaluating the overall efficiency of the system and informing the customer of equipment condition.
Temperatures and performance will be recorded. An accurate record of vital data can indicate potential problems that can be eliminated before they become expensive repairs. All panels will be secured—loose panels can increase operating costs and cause a dangerous condition and may shut down the furnace.
Checking overall system airflow.
Airflow in your comfort system is like the blood in the human body. If you don’t have enough flow, some serious problems can occur. Airflow is probably one of the most important variables associated with a properly operating system.
Additional Heat Pump Procedures
Inspecting and testing heater elements.
Heat strips that aren’t operating properly can cause a loss of heat and increased electrical costs.
Inspecting and testing the reversing valve.
A reversing valve that isn’t operating properly can waste energy and cause heat loss.
Inspecting and testing defrost system.
A defrost timer that isn’t working properly can cause heat loss and shorten the compressor’s life.
