"The best experience ever with a HVAC company. They were able to come right out and pricing definitely was better than others. The gentleman who came out was professional and helped me with the air conditioning issues than the previous company who came out. He found things that should have been detected by the previous company that were not. He took his time did the work and had me enjoying my air conditioning in a timely manor. Will be using them for my duct cleaning next."

"We found CLIMATE MECHANICS from their stellar reviews while searching for a knowledgeable and competent HVAC company. For years, we were dealing with a condensation problem with our LG mini split air conditioner, and no one could find the source of the problem. We can honestly say that we've never experienced a company like CLIMATE MECHANICS so committed to making things right. Nate, the awesome climate mechanic that came to our home, and Robert, the owner of the company, could understandably have walked away because they did not install the system and were not responsible for the problem. Nate worked for hours trying to locate the problem. In the end, after so many years of leaking, CLIMATE MECHANICS went above and beyond and resolved our ongoing problem. Toni, their wonderful contact person, told us repeatedly that Robert just wanted us to be happy in the end. And we are. Totally. Thank you Robert, Nate and Toni."

"It was good. I had to buy another chimney sweep right after that. I purchased my home and had the inspector go through the chimney. He said I had some issues. I use Nu- Air for a second opinion. They said everything was fine. They didn't really do a through check, they were in and out. So, I then got a third opinion, it was pretty extensive it cost me a little bit of money. It included a camera test. They found a lot of issues with my chimney which I then had to get repaired. My two opinion versus their one was a kind of a little bit of risk. For the chimney sweep specifically over all was a waste. They did clean the chimney. The person could have done a better job. They tried to sell me another service when they were there. But I pushed back, obviously I could tell that they weren't going to be a reliable business partner. I expected a lot more from them."

"Vaughan company was very responsive to my call and scheduled the work on the same day. Anthony tested the AC unit and determined that it needed coolant added. The work was completed quickly. House is cooler now and AC is keeping up with the hotter temperatures."

"Adam and Nate installed my new HVAC system in my home. This is my second time dealing with Adam since 2013. Adam is very honest and professional. My family is very satisfied with our new AC system. I would definitely recommend these guys for all of your heating and cooling needs."

"Very happy with the job these guys did. I was a little hesitant on the price quoted for my little house, but glad I had it done. These guys did one **** of a good job. First, they arrived 15 minutes early. Then they walked me through the job step by step. When they were done, my carpets and upholstery looks and smelled brand spanking new. The ducts in my 54 year house were spotless and I could tell the difference in the air quality right away. And they cleaned my one little dryer vent for free. A+ service. I definitely recommend this company."

Air Conditioning FAQs, answered by experts

It’s never a good idea to run your AC without a filter, even just for a night. The filter defends your HVAC system from the dust, dirt, debris, and other grime in your home. Without a filter, those contaminants are more likely to get inside your system and potentially damage it. 

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.

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.

Modern AC leak sealants work as a temporary measure to stop refrigerant leaks. You can purchase them at most home improvement stores or on online. When using an AC leak sealant, keep in mind that it’s only a temporary solution, so you’ll still need to hire a pro to install a replacement part as soon as possible.

If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.
