Home warranty sent us MD Denna after having issues with a different contractor. The experience I had with the previous contractor compared to MD Denna was day and night. MD Denna’s technician was knowledgeable, on time, and was able to properly diagnose the issue with my furnace. He was polite and easy to work with and answered any questions that I had.

If you’re looking for a heating and cooling guy, look no further. I’ve had a full AC unit replacement, boiler repair, thermostats installed, registers cleaned, and more!! Every job was thorough and accurate. Very few operations come and go without a follow up call to address something that was forgotten. Not once has that happened with MD Denna. And it doesn’t matter what crew you get; they all are top notch. Always willing to explain as many times as it takes for you to understand. I’d recommend these guys 100% of the time.

Mike, the owner of MD Denna, came out to our house for an a/c service call recently and was extremely professional and courteous. He took the time to educate us on our system as no other company has done in the past. There was no high pressure to purchase additional service/new equipment. Also, prices are reasonable. We highly recommend his company!
