  • Rich Johnson
    My ac went out on a °93 day. My house warmed quickly and I didn't have time to fool around. A friend referred Maichle's and I called. They had the part I needed on the shelf, offered me a decent price (considering my situation), and came out at 5:30pm in the pouring rain and installed the part in my outside condenser. And the man did it with a smile, quickly and correctly. That kinda service is hard to beat and greatly appreciated.
  • Rachel Hughes
    They are extremely helpful, on time, knowledgeable, caring, professional, and decently priced. Every time they come out they give a call ahead and also explain what is happening. If anything needs to be addressed further they explain and also leave an invoice on the detailed work performed. Always job well done.
  • Laura Mohr
    I can not say enough about the Maichle's team. Always on time, honest, knowledgeable, and an overall pleasure to deal with. They made a temporary fix to our AC, even stopped out on a Sunday for an emergency visit which was much appreciated as we had a small gathering at our house and it was the hottest day of the year! Last week they installed a new AC and furnace. Again, on time and respectful. Would 100% recommend this business to anyone in the need of HVAC services.
  • Patti Tucker
    We have been using Maichle's services for about 25 years! They are always professional and very helpful. If something needs replacing or repair, they are usually here the same day and the problem is always solved on the first visit. Their maintenance plan is very cost effective and makes it easy for us to schedule payments as well as AC, heating and hot water heater maintenance and/or repairs! They are AWESOME!
