"This is an excellent company. We have used them for year to service our heating and air conditioning units. It became necessary to think about replacing the units. We have two. Decided to replace both at the same time. They came out on a Monday and gave us an estimate and came out on Thursday and Friday to do the work. They totally cleaned up after themselves and made sure everything was working properly. Then they called a few days later to see that everything was working well. I highly recommend this company. All the technicians are polite and competent. The office staff is nice beyond belief. If you need any heating/AC work done, this is the company to do it."

"They did a great job, it is part of a warranty that I have with them. When this condo, they were the HVAC that put the air conditioning, ducts and all of that in this building, they were the ones. They have this wide window where you have got to stay in your place from 8 to 12 or 12 to 5. They did a nice job."

"My air conditioning unit and furnace were nearly 20 years old and beyond repair. It was June and the temperature was rising fast. Yonas, with AHS provided the best estimate. In two days, AHS technicians were at my home, on time, and very professional. They respected my home (shoe covers, etc) and informed me of everything they would be doing and explaining why. The new AC unit and furnace were completely done in about 5 hours. They also discovered duct in my attic that had mold and replaced it while they were there. Lastly they installed a new eco friendly thermostat. They cleaned up after themselves and took me around to ensure I knew how everything worked. I was also given warranty paperwork and assured, follow up service, if/when needed. I had a wonderful summer knowing my AC unit was good to go. I highly recommend AHS!"

Air Conditioning FAQs, answered by experts

No, it isn’t necessarily bad to turn your AC on and off frequently—contrary to popular belief. Even if you stop and start your AC throughout the day, it won’t use as much energy as it would if you ran it nonstop. 

If you’re concerned about your power consumption and energy costs, there are a few simple ways to use your AC more efficiently. Regularly cleaning the filters, scheduling routine maintenance, and using a programmable thermostat are all great choices.

The $5,000 rule for HVAC systems helps homeowners decide whether to repair or replace an AC or furnace. Take the quote for the HVAC repair cost and multiply that by the age of the HVAC system. If the total is higher than $5,000, it’s more cost-effective to replace the system. If the total is lower than $5,000, consider repairing the system.

You will only need to refill your AC with refrigerant if it has a leak. Otherwise, a modern, well-maintained AC will most likely never need a recharge. You may notice a leak in an older system if your bills are higher, you hear a hissing sound, or if the air is blowing out hot.

HVAC pros recommend that you replace your AC filter every one to three months to maintain optimal indoor air quality and ensure your HVAC system operates efficiently. However, factors such as filter type, household size, and environmental conditions may influence the frequency of replacement. Regular filter changes help prevent debris buildup, maintain airflow, and prolong the life span of your air conditioning unit.

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.
