We provide the following services, recommended annually, for residential preventative maintenance (tune up):

Safety is our number one priority in meeting your HVAC needs. You wouldn’t drive your car 100,000 miles without changing the oil. The same logic holds true for your home comfort system. Regular HVAC preventative maintenance is the best way to ensure trouble-free operation and peak performance. Pre-season maintenance is also important. It can help to avoid a system failure in severe hot or cold weather when you need it most, and it can also keep your energy bill from getting out of control. The old adage is true: an ounce of prevention is worth a pound of cure.

“Dayton did a great job installing our new Trane variable speed furnace. Nick stopped by and gave us a fair quote. Loved how they gave the options and then we could pick what was best for us and our budget. Installers, Zach and Austin, were proficient, professional and hard working! They both smiled and got the job done. Everything was picked up and perfect. And the furnace is already heating our home better than it’s ever been! We have a 2nd story home that has NEVER heated or cooled our upstairs very well. Our new variable speed Trane furnace from Dayton has FINALLY solved the problem! So happy!! Thanks Dayton!!!”

“I had to have a new furnace installed due to a failed heat exchanger on an old furnace. Nick with Dayton gave me a great quote, and they are a Veteran owned company too. From last Thursday when the problem was discovered I started getting bids. I got my last bid Tuesday and gave Nick the green light on Tuesday night around 7:00 pm. He scheduled the job for the next morning – now that’s quick service! His crew, ran by Scott, was very professional, and did an outstanding job! My furnace was in a fairly tight location which made it a long day for the crew, they stayed and worked without breaks until it was up and running. Professionalism, and dedication to doing the job right. I am very happy with their work, and I highly recommend them to anyone.”

“As always the technicians from Dayton Heating and Cooling did a knock-out stellar job of installing our new furnace! Kind, considerate, quick and very clean. They wore their booties and even spread a red plastic carpet liner on the areas where they were frequently going to walk to cut down on tracking dirt and other substances on their shoes. Always friendly and efficient! Thanks!”
