"I can not say enough positive about Chris and Chuck and O 2 KOOL!! Chuck came out in early January to look at my old Trane gas furnace .. he got it going with no trouble. Now today ... during our ice/snow armageddon it went out again. I called and Chris FaceTimed with me .. looked at what was up and talked me through how to relight the system myself. Good news .. I now have heat! I strongly recommend them to anyone who needs help with their heating and cooling system! They not only helped, but assured me .. a 60 yr old woman .. everything would be OK and safe. That is a VERY rare quality!"

"O2 Kool servicers contacted me less than a minute after filling up my search on home advisor. I explained my issue and they came to my home within a few hours. They identified several problems that I wasn't even aware of once they began inspecting my HVAC unit. By 1:00 the next day they completely installed a brand new system. I was very pleased with the service from these gentlemen and would highly recommend them for any way needing HVAC service in the future."

"I had such a dismal experience with local carpenters, who lied to me and did not understand the basic HVAC. I found this company when I was searching for a better business, and they have all been excellent. From their company representative who came out to give me a bid, to the techs that cleaned my vents for me, everyone has been professional and helpful. I really appreciate that their technicians are on time and clean our office with care -its worth every penny"

Heating and Air Conditioning FAQs, answered by experts

While 72 degrees is a comfortable setting for many people, it’s likely not the most efficient temperature setting for your air conditioning unit. By pushing the temperature up to 75 or 78 degrees, you stand to save money on your energy bill. That said, these temperatures may be too warm to be comfortable for some people and are definitely too warm for most people to sleep comfortably.

You might notice that your air conditioner isn’t running as effectively as it once did. Specifically, your AC unit could take longer to cool your home, or it might struggle to remove humidity from the air. Higher utility bills and hissing sounds coming out of your AC could also indicate a leak.

The simplest indicator is how long it’s been since your last tune-up. You should schedule an annual AC tune-up each spring. Beyond that, there are multiple signs that your AC needs a quick check by a professional. These issues include higher-than-average energy bills, decreased air flow from vents, higher indoor temperatures, and an air conditioning unit that stays on all the time or frequently turns on and off.

Swamp coolers cost approximately 50 percent less to install than central air conditioners and cost less to run. Operation costs depend on the size of the unit and home, your climate, utility rates in your area, and the system’s efficiency. Swamp coolers use 15 to 35 percent less power than air conditioners.

A window AC unit is not completely silent. You’ll hear the sound of air blowing, and if you put your ear right up next to the unit, you may hear a slight hiss or gurgle as the refrigerant flows through the system. That said, if your system is making a running water sound, a loud banging sound, a grinding sound, or physically vibrating, you may be facing an issue or malfunction with your AC unit.
