Our Frequently Asked Questions
Nothing is more frustrating on a blistering hot day than for you to turn on your AC and only get warm air. So, what’s going on? Depending on the type of AC system you have in your home/condo/apartment there could be a number of factors contributing to this deficiency.
Refrigerant Leak: A refrigerant leak or low refrigerant levels can lead to a lack of cooling capacity in the AC system.
Dirty or Clogged Filters: Dirty or clogged air filters restrict airflow, reducing cooling efficiency.
Thermostat Issues: A malfunctioning thermostat may not accurately control the temperature, leading to poor cooling performance.
Electrical Problems: Faulty wiring, capacitors, or relays can disrupt the AC’s ability to cool.
Compressor Problems: A malfunctioning compressor can prevent the AC from cooling properly.
Evaporator or Condenser Coil Issues: Dirty or damaged coils can impair heat transfer and cooling.
Clogged Coil Tubing: With chilled/hot water fan coil unit systems (typically found in older condominium and apartment buildings) the fan coil unit (FCU) is connected to the main closed loop system. This closed loop system send either chilled water or hot water through pipes that travel all through the building, and feed each FCU. If that water is not flowing properly, or is not of the correct temperature, or has so much rust/debris from aging pipes traveling through it… it will cause issues that present at the FCU. Often we find debris and rust from old steel pipes has become lodged in the coil tubing of the FCU thus restricting water flow through the coil, resulting in degradation of the FCUs performance.
The best way to ensure your air conditioning system is ready for the summer is by scheduling a professional tune-up and cleaning in spring.
As you might know, the refrigerant R-22 (Freon) has been getting phased out of circulation in the United States since 2010, due to environmental concerns, specifically ozone depletion. So, can you still get a refill if you have an older air conditioner that runs on Freon? As of now, the answer is yes, but it’s extremely expensive if R-22 is being used since there is a very limited stock of this refrigerant and the market rate of a jug keeps increasing as supply dwindles.
If you have an older R-22 HVAC system and your system experienced a refrigerant leak, there are a couple realistic options you should consider. Replace the existing system as its likely at the end or beyond its useful life at this time. If replacement is not an option at this time, there are many refrigerant blends that are compatible with R22 systems which can be used in lieu of the very expensive R22. However just make sure your contractor is properly evacuating your existing system from any remaining R-22, repairing the actual cause of the leak, purge the line sets with nitrogen, holding a vacuum, and using the correct blend for your system’s application.
R-410A is currently the most widely available refrigerant for residential HVAC equipment and is what current equipment operates using. We are getting ready to go through another phase-out (of R410A) just as we did with R22 but that will be a lengthy process so there should not be immediate impacts for any R410A systems currently being installed. Regulations are constantly changing, so it’s best to consult your local HVAC professional to discuss your options when you’re low on refrigerant.
If your heater runs on gas, propane, or oil, you might be worried about the risk of fire. Modern furnaces typically don’t catch fire under normal operating conditions because they’re designed with multiple safety features to minimize risk. However, there are things you should be aware of.
One of the most common fire risks with furnaces is a malfunction in the heating system. Faulty electrical components, damaged wiring, or a malfunctioning gas valve can lead to overheating, sparks, or gas leaks, which could ignite.
Additionally, there could be a risk if your furnace wasn’t installed by a certified and properly trained and licensed HVAC professional.
Here’s what we recommend to ensure your safety.
Schedule annual furnace maintenance and inspection by a trained professional.
Replace filters as the manufacturer recommends to maintain proper airflow and prevent overheating.
Keep the area around the furnace clean and free from flammable materials.
Install smoke and carbon monoxide detectors and test them regularly.
Educate your family about gas safety and be vigilant about signs of leaks, such as a sulfur-like odor.
You hear it constantly: It’s essential to get your heating and cooling system tuned up at least once a year. But is annual maintenance really necessary? Yes, and here’s why.
Firstly, annual maintenance and tune-ups ensure your system is always operating at maximum efficiency. This means better comfort and lower energy bills.
Regular maintenance can also extend your system’s lifespan by several years. When you consider how much a heater or air conditioner replacement is, it’s smart to do everything to get the most life out of your current unit.
Professional maintenance is key to preventing sudden system failure or breakdown when you need it most. Replacing worn-out parts and addressing minor issues before they escalate protect your system from giving out during a heat wave or cold spell.
Most new air conditioners and furnaces have a manufacturer’s warranty covering repairs or replacements for a specific time. However, these warranties often stipulate that you must keep up with regular professional maintenance. Failing to do that could result in your warranty claim being denied and you paying out of pocket for an expensive repair.
