Testimonials

When I called to get a quote, the lady who answered the phone was very respectful and answered all of my questions. A young gentleman came out and gave me a quote for a new furnace and A/C. He was very knowledgeable and very honest. The quote I received was not the cheapest, but very reasonable. I went with A-1 for my install and they did a beautiful job and my system works great. I would recommend A-1 for any of your cooling and heating needs.

Testimonials

Slade has been our furnace repair man for the past several years. My husband and I could not be more pleased. He ALWAYS comes immediately when we call –even giving us his cell number in case we had a problem after a particularly large repair. He knows us and our family and is always very professional and efficient. He always spends time trying to explain the repairs that are needed and we have never had to wait for repairs to be performed. On this particular occasion, he upgraded the unit he repaired but actually found us a discounted part saving us a few hundred dollars. Slade has never disappointed us!

Testimonials

Wonderful customer service! Communication is always timely and professional. We’ve had our AC and our furnace checked out annually by A-1 for many years. Usually, A-1 contacts us before we need to call them, to schedule the annual maintenance checks. This is much appreciated in our busy world! Being proactive is always a huge plus! Better the problems that never occur due to careful maintenance than the ones needed due to sluggish maintenance. Thank you A-1 for your top notch customer service and professionalism.
