"Best HVAC company I've had to deal with for a long time. very professional, courteous, goes beyond the job to get a repair or install done right and timely. they're also the best bargain and use superior equipment compared to other companies. from the moment I contacted them to the last details of the job they shine high above other irresponsible companies out there. I highly recommend them."

"I own a business and had a company come out to fix our air conditioner. They came out 4 times, charged for all those time and the unit still was not working properly. I then decided to try someone else, so I called Thermotech on the referral of a friend. They came out, diagnosed the problem within 10 minutes (it was an old crumbling circuit board), showed me that bad part, ordered it and had it fixed in less than 24 hours. We have not had a single problem since! I was so happy with their service that I ended up using them for my home HVAC system.. I even referred them to a family member and they did a home install of a brand new HVAC system and they were very happy with the price, install, workmanship & fair pricing. Thermotech has found a customer for life with me. I have had so many bad experiences over the years with other companies telling & thermotech has been a game changer."

"Worked with Andrew - he was quick to communicate, included all necessary details, and kept in touch. He and his crew (Alex and Andre) showed up on time and had the whole deck demolished and cleaned up in only 2 hours. Would definitely work with him again."

Air Conditioning FAQs, answered by experts

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.

When deciding whether to repair or replace your air conditioner, several factors should be considered. It is generally worth repairing the unit if it's less than 10 years old, the warranty is still active, and you're dealing with a one-off issue. Most central AC units last about 15 years, while window units last 8 to 10 years. If your unit is approaching or has surpassed the 10-year mark and requires frequent or costly repairs (e.g., over $5,000), replacement is often the more sensible long-term investment. For older, inefficient, or out-of-warranty units experiencing multiple problems, replacing it is typically the better choice.

A few drips here and there should not be cause for concern, but if your unit is leaking a large amount of water, then it’s advised that you stop using it until the problem is identified and a solution is determined. The more you use it during a leak, the more issues it will cause.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

You will enjoy greater energy efficiency and save on your annual energy bills, with new, modern HVAC systems using 30% to 50% less energy than older models. Upgrading your HVAC system is also a great way to embrace new technology, such as smart thermostats, lighting, fan speed, and humidity from your phone or tablet.
