"M&H Air helped upgrade Gas furnace/ Forced air heating system, by adding new ducts and vents in basement to help create more comfortable living space. Also has provided great preventive maintenance service to my Heating and A/C system!"

"After being ghosted by several AC companies we were thrilled to have Behold answer their phones, make and keep appointments, and show up for the install. Our 1970s house is blazing hot upstairs in the summer, and after considering several options we settled on a mini split. It was installed today and our bedroom is delightfully cool. Both guys on the job were professional and courteous. They kept us appraised of what they were doing and showed us how everything worked at the end of the day. They have also promised to file all applicable rebates."

"Dale is my new AC guy!!"

"Great communication! Was able to send a video scope up the vent and ran a air flow test. Price was great."

"Great service and came out the same day to winterize the swamp cooler and sell me a cover. I will be calling them again!"

"I recently had Comfair Heat and AC install a new furnace, and I couldn’t be happier with the experience. From start to finish, the team was timely, professional, and incredibly friendly. They showed up exactly when they said they would, walked me through the process, and completed the installation efficiently without cutting any corners. Their pricing was very fair compared to other quotes I received, and the quality of their work truly stands out. The new furnace runs perfectly, and the difference in comfort is noticeable already. Overall, Comfair delivered fantastic service, and I highly recommend them to anyone needing heating or AC work. I’ll definitely be using them again in the future."

"Tony was very easy to work with and accommodating. I had narrowed my choice to 3 firms. Elevation was not the cheapest nor the most expensive but I felt most comfortable with Tony and believe he offered the most value. My air conditioner was installed today, I hope this will be the start of a great (and cool) relationship."

"Am so impressed with his skills he saved me so much money I added air had some problems it was operate error he talk me through lt late at night and got it going"

"Jasmin is a professional who always do more than expected, She came to inspect our AC to ensure everything was in order. She is not only a technician I ask for by name, but we also consider her as a friend. She is courteous, polite and a tech that will tell you the truth of the conditions of your product. Thanks Jasmin!! God Speed!"

"We had 1st Action Plumbing, Heating & Air Inc install a new furnace and A/C system in our home about three years ago, and we couldn’t be happier with it! The system has worked amazingly well and has been reliable ever since. We had a great experience with the installation and would definitely recommend 1st Action to anyone looking for quality HVAC work and a company they can trust!"
