I spoke to a technician over the phone to try and troubleshoot some problems I was having with a reverse polarity code. Nothing was working. Not soon after, Chris shows up. Does a quick diagnostic and finds my board is fried. He leaves to gather material and is back quickly to install the new board. As most might know, once you fix one problem...you find another. Chris made some quick adjustments and got me running some heat in this house so my dog doesn't freeze to death. Thanks to Eric, Doug and Chris for all that you do. And those nice people in your office, who are always so understanding and helpful.- Cory A.

I'm very happy with Martin-Jetco. I have had a lot of disappointing experiences with other HVAC people and I'm so happy I finally found someone who will take the time to do it right. They really went above and beyond to fix everything even though it was more complicated than the initial bid.- Angi N.

AC went out and it was a bit of a puzzle as to why. Shout out to tech John DeClue who came out at 4:00 on a Friday and figured it out. Was a bad wire causing a short. Looked like a maybe a bad compressor, but he worked the problem and found the solution that saved me a lot of money! Martin-Jetco is a great company.- Ken M.

Just hired Martin-Jetco to install a new AC system. Sales Manager Douglas met with me and reviewed my options. He was very nice, knowledgeable and honest about my quote. Gave me a few options and explained everything. The installers were also very nice and took care of everything with no mess. I got 4 other quotes and these guys are super competitive on price and transparent. Solid work.- Colin D.
