"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."

"We called a week earlier for a quote to clean the ducts and returns of our heating and AC system.  The quote was reasonable and an appointment was made for the following Friday.  Ron called thirty minutes prior to the appointment to confirm we were available.  He and Danien arrived on time and explained what was involved in the cleaning process.  They were very courteous and professional as they went about their work and they carefully replaced anything they had to move.  We had an opportunity to ask questions after they finished working and their answers were responsive and complete."

"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

You should use a breathable, weather-resistant cover with ventilation. It can be a top cover or a full cover that has mesh to allow airflow. A full, non-breathable cover can cause moisture to build up, leading to rust, frozen parts, and corrosion. A full cover also attracts unwanted critters, such as mice, that can damage the wiring and your unit. If you need to protect your AC unit from falling icicles, choose a sturdy top cover or piece of wood that prevents icicles from damaging your unit.

If there’s a freon leak in your home’s AC unit, it will cause the system to work overtime to cool the house. That issue will result in higher energy bills and it will take much longer for cool air to disperse throughout the home. If your system has a freon leak during the summer, it can make hot days miserable. That’s why it’s important to hire an HVAC professional to resolve a freon leak as quickly as possible.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

Here’s how AC professionals will clean your AC coils:

  1. Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.

  2. Remove the faceplate.

  3. Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.

  4. Use a soft-bristled fin comb to remove stubborn caked-on debris.

  5. Use the vacuum hose to suck up any extra debris.

  6. Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.

  7. Let the solution sit for at least 15 minutes.

  8. Gently wipe away loosened grime and debris with a microfiber cloth.

  9. Reattach the faceplate, plug in your AC system, or turn the breaker back on.

If your central AC is not blowing cold air, you should try resetting the system. Many systems have a reset button. Make sure your thermostat is off, then turn off the circuit breaker that powers your AC. Hold the reset button for three to five seconds, then turn the circuit back on. Set your thermostat to cool and choose a temperature cooler than the room. Your system should turn on quickly.
