"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

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

It’s normal to hear a low humming sound as air moves through your vents. Most of the time, you probably won’t even notice it. However, if that sound becomes disruptive or if you hear more concerning noises (such as rattling, clicking, banging, hissing, or grinding), there might be a problem with your HVAC system.

Signs that your air conditioner capacitor is bad or failing include a range of symptoms. The AC unit may not turn on at all, or it might struggle to start before shutting down randomly or in the middle of a cooling cycle. You might hear a humming or banging noise when it attempts to start, or the compressor might hum without the unit actually running. Other indicators include a smell or smoke coming from the unit, the blower circulating room-temperature air instead of cold air, and an unexpected increase in your energy bills.

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.

Split systems are the most common type of HVAC system. Split systems have two main units: an indoor one and an outdoor one. These units work together to pull in air, heat or cool it, and distribute it throughout your home. Other popular types of HVAC systems include hybrid systems and packaged heating and air systems.
