“My AC quit during a hot Memorial Day weekend with kids at home, and after multiple calls with no luck, Tony came through. He responded quickly, diagnosed the issue fast, and provided honest recommendations to help avoid future costly repairs. Fair pricing, quick service, and great experience overall. I highly recommend Tony Ruth at A Plus Air for any HVAC needs — you won’t regret it!”

“A-Plus did a very thorough inspection of my 10 year old HVAC system. They were here for approximately two hours. They did not try to fabricate any mysterious issues with my unit. Fair price! Also, he was already in our neighborhood shortly after for an unrelated issue and he arrived in about an hour — made the simple repair and did not charge me a dime. I trust this company completely.”

“Total pros, straight shooters, well equipped, professionally trained, highly ethical! They will carefully identify your problem, fix it, and won’t sell you goods or services you don’t need. We trust them completely. They came out after one of the larger companies quoted me a massive price for repairs. These guys saved me over $1,400, were fast, professional, and took time to make sure I understood what was going on.”

“Tony and John checked out my HVAC just prior to the summer season. I am an electrical engineer by education and was very impressed with the quality of their test equipment and their knowledge regarding how to read the gauges and interpret readings. A Plus Air is my HVAC maintenance and repair company! Thank you Tony and John for the thorough work.”

“I have used A Plus Air HVAC company multiple times at a few locations, and they’ve been excellent every single time. The response is always prompt — no waiting days for an appointment, and often same-day service. What I appreciate most is their honesty. They provide detailed, transparent quotes with photos, explain exactly what they’re seeing and why, and lay out several repair options with the pros and cons of each — no pressure, just straight answers. Highly recommend.”
