#80816 Always a Great Experience dealing with this company and their people. Twice a year we have our heating and air conditioning inspected and freshened up so that we get efficient performance throughout the year. Today, was no exception. Our A1 technician completed his inspection of our furnace, cleaned it and made necessary adjustments. He also reviewed the best practices for humidifying our home during winter months and de-humidifying during the summer months. Always something to learn. Much appreciated.

Amazing company! I had a problem with my furnace so that there was no heat. I had called another company who spent 1.5 hours trying to diagnose and change parts to repair it to no avail. Frustrated at not having it repaired, I checked the online reviews looking for a solid company with a good reputation and settled on A1 thinking I might need a new furnace. "John" attended the house and was very professional and methodical about his work. He spent approx an hour doing a variety of tests and inspections of the various components. He determined that the gas burners needed a thorough cleaning inside even though they first appeared not too bad visually. He quickly got me up and running and now the furnace runs great. John found the problem that the other company missed. The price for the service was very reasonable. I will definitely use A1 again should the need arise. Thank you A1. #80812

#79622 We have been using A1 for many many years for both our air conditioners and furnaces. We have purchased all equipment from A1over the years for 2 homes. Salesmen are knowledgeable and a pleasure to work with. Maintenance service is always completed thoroughly and we know when they leave our equipment will be running well. We would not go anywhere else and we would highly recommend A1 Air Conditioning & Heating.
