"Based on prior experience with Cool Air Technologies and its owner, Bill McIntosh, I chose them to replace my HVAC system. I was not disappointed. Bill and his staff were friendly and professional, communicated and resolved issues found, and completed the work as scheduled. I happily recommend Cool Air Technologies."

"Nathan and Gordon at Total Home Environmental are lifesavers! I was facing estimates of $10,000 to $20,000 to replace my entire AC and heating system but instead they indicated that my 25 year-old AC compressor could be resuscitated by thoroughly cleaning the terminals and adding a hard-start kit. No other HVAC technician that came out gave me this option but they pulled it off for a fraction of the price of a new install!!! They are honest and knowledgeable professionals! Thank you so much!"

"Chris came by for a normal AC tuneup and as he was finishing up, we told him about some issues with our dishwasher and master bathroom sink and asked if he knew a plumber. He took care of both our problems right then and there! I’m not sure there’s anything he can’t fix. Chris is our go to guy for EVERYTHING ac/furnace/plumbing and he should be yours too!"

"Very knowledgeable, professional, and great customer service! Penguin, serviced our central AC & Heat and they explained everything to us before performing the work. They also replaced our moldy insulation in our attic. They packed and transported the old moldy insulations, ensuring that the mold does not spread, and they left our house free of any mess. I'd recommend Penguin Heating and Air to anybody in need of AC/Heat service, repair, or installation."

"Called in the morning, Bernie arrived in the afternoon and within 2 days we had a new AC unit located on the roof which requires a crane to install. I would highly recommend Air ASAP as you will not find anyone better nor any better price."

Air Conditioning questions, answered by experts

The decision to put your AC unit on the roof or ground depends on the climate in your area, the roof shape, accessibility, and budget. If you live in a warm climate or don’t have existing ductwork, it’s likely best to stick to a traditional AC unit that sits on the ground. However, if you lack yard space, live in a mild climate, and have easy access to the roof, your home may benefit from a rooftop AC unit. 

When first installed, flex ducts shouldn’t cause airflow problems in your home. However, because flex ducts aren’t the sturdiest and require extra support, they lose their durability over time and begin to sag, which can inhibit airflow down the road. Also, if your flex ducts aren’t tight enough, your HVAC could work twice as hard for the same air pressure. If you’re worried about the airflow in your home, a rigid duct may be your best bet.

Yes. Return air vents are responsible for gathering and pulling in the warmer air. Once they draw it in, your system conditions the air by removing the warmer molecules from it, allowing your air conditioner to dispense the cooler air back into your home. Not only does this create a more comfortable environment for you, but it also keeps your air conditioner from overworking, resulting in lower energy bills. 

While most air conditioners can last between 10 and 20 years, they will only last this long (or longer) if properly taken care of. Routine maintenance and inspections help keep your AC unit running in tip-top shape but understanding what factors will decrease its lifespan will also help keep your unit running cool.

Some things that shorten your AC’s lifespan include:

  • Extreme outdoor conditions, like high humidity or extensive salt spray 

  • Improper installation

  • Extended run times, either by the unit being too small or the thermostat setting too low

  • Not performing required maintenance

It depends on how fast an HVAC technician can resolve the issue. First, if there's a refrigerant leak, you’ll want to keep small children and pets out of the house. Next, you’ll want to turn off the AC unit to ensure no more freon enters your home. Finally, you’ll need an AC technician pro to come to your home and fix the leak immediately. Ultimately, it’s best to leave your home if you discover a freon leak—the risk of exposure is very high, and it’s not worth risking your health to stay.
