"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."

"Had an amazing experience! This was the second time using this company and again I was not disappointed!! The guys showed up on time, were very professional. Explained what they were going to do. Since I had just bought a new house and the vents were so dirty they said they would like to use a disinfectant. It’s very nice to have piece of mind knowing that my air and dryer vents are nice and clean! I would definitely recommend them."

Heating and Air Conditioning questions, answered by experts

You may be able to clean mold from your air conditioner in some cases. If the mold growth only takes up a small area, you can use either vinegar or bleach mixed with water to remove it. Larger areas of mold should be left to the professionals, though. It's also a good idea to leave mold removal to the pros if you are sensitive to mold or have asthma. 

A power outage can damage your air conditioner, just like a power surge can damage any electrical device or appliance. In most cases, your circuit breaker or built-in surge protection on your AC unit protects your AC and just needs a reset. But in other cases, it might be that your AC compressor or capacitor was blown during the power surge. You’ll need to have an HVAC professional repair or replace any AC parts. 

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. 

Yes, it’s best to turn off an AC unit that’s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.

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.
