Customers say: Super punctual

"Very warm weather.  Home of elderly mother.  A/C stopped working the evening before.  A quick call to Hoff the following morning received a very prompt response that day.  Mike diagnosed the problem immediately, telephoned me with thorough explanation of problem and cost, and took care of the matter in a short time.

I have no doubt that Mike remained long enough to ensure that his repair was appropriate, and that no other repairs were necessary.  There were no other A/C failures during the remainder of the cooling season.
Highly recommended."

"If you're looking for friendly and exceptional service for your Heating and Cooling needs, I highly recommend Armor Air! Ever since we moved into our home several years ago, we dreaded the winter dryness (our home routinely would be anywhere from 25-29% humidity in the winter, and sometimes even lower. We were constantly sick, waking up with a sore throat, and frequent nose bleeds. I saw a video on Instagram of the Armor Air team and they looked like a bunch of really nice people, so I investigated and saw how many people had great things to say about the company. We had them come out and give us a quote on a whole home humidification system, and Robert was very friendly, professional and worked with us to get a system setup for our home. A few days later, Kameron came out and installed the system and he did an awesome job! The last time we had another HVAC company come out and do work on our system, they left a giant mess, but not Kameron. You couldn't even tell he was there! Now,"

"I hired them to do a diagnostic evaluation of my HVAC unit. He seemed to do a thorough job of identifying the problem and he offered me 3 possible solutions ... unfortunately all 3 were a bit out of our price range so we're going in a different direction."

Heating and Air Conditioning FAQs, answered by experts

Running an air conditioner with mold is not safe because it can spread harmful mold spores throughout your home. Exposure to these spores can trigger various health problems, including respiratory issues, allergies, coughing, wheezing, sneezing, itchy eyes, and a sore throat. It may also aggravate asthma in household members. Continued exposure can increase the risk of more serious illnesses like sinus infections, pneumonia, and bronchitis. If you suspect mold in your air conditioner, you should stop using the system until it has been properly cleaned to avoid health risks and further contamination.

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.

Both evaporator coils and condenser coils are recyclable and contain valuable, sellable metals such as copper and aluminum. Not only is it more earth-friendly to take them to a local metal recycling facility, but you can also trade them in for cash. Also, once the coils are removed from the system, they won’t have any traces of refrigerant, so you won’t have to arrange for recycling Freon or R-410A unless you’re disposing of the entire AC system.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

While an air conditioner can temporarily run with a dirty filter, it is not recommended as it will not work efficiently. A dirty filter forces the system to work harder to circulate cool air, leading to reduced airflow, increased wear and tear, and higher energy bills. This added strain can cause the air conditioner to overheat or fail prematurely. Furthermore, a clogged filter may allow dust and dirt to accumulate in your ductwork, negatively impacting air quality. It is more cost-effective to clean or replace filters regularly than to pay higher utility bills and risk needing to replace the entire AC unit.
