We have been regular customers ever since another HVAC service tried to convince my wife that he thought he heard a bearing going out. (She wasn't buying what he was selling.) We had a lot of bearings in our farm machinery when I was growing up, and I knew very well what a bad bearing sounded like and that wasn't…
No air conditioning in the house Maertin Heating were able to come and determine the fan on furnace needed to be replaced. Since the furnace was 25 years old it was time to replace it. Interesting fact, Scott Maertin installed our furnace 25 years ago! They arrived the very next morning and installed a new furnace…
Called Martin Heating and Cooling for service and as always prompt service. They are great. Scott and his team are very trustworthy and knowledgeable. We have been working with them for as far as I can remember (years) and do not ever think to call anyone else with HVAC issues. Ended up replacing both furnaces…
Excellent response from Maertin, and the technician that was sent out was personable and able to diagnose my problem with the furnace very quickly. He was able to fix the problem and the furnace is now running very nicely. He answered all my questions and gave me advice on keeping the furnace running well into the…
On time and worked done in a timely manner
Highly recommend! Very responsive, understanding, and patient. Let me know the steps I needed to take for my safety and had someone out the next day. Very compassionate company!
Always professional and honest. Appreciate Maertin as always.
We’ve been using Maertin for a while. Josh has been coming to our home several times. He is knowledgeable and very professional. Thank you
Furnace went out late Friday night. Called Saturday morning. They were there in less than an hour. We needed a new furnace (we were well aware of that) and it was quickly installed on Monday. Very professional. Highly recommend and Thank you!
Rich was very informative and professional. He cleaned my furnace and installed a new Pilot light assembly. So far, so good.
Rich explained everything thoroughly and fixed my boiler.
Very professional and informative!!
I regret not starting this process with Maertin from get go. They had installed a boiler in my previous home about 14 years ago. In my current home, I had a bleeder valve go bad on my 5 y/o boiler. I contacted the company (Climate Control) that installed the boiler and he said his office would call on Monday to…
I could never cool or hear my ground level family room sufficiently until maertin installed the zoning system which not every company can do. So thrilled with this system and their work!
Professional Service , but my repair was pricey!
Called Maertin Heating on a Sunday evening when they were closed and they came out the next day. It was a simple fix on the furnace and Paul had the parts in his van. They were on time and completed the work. I would recommend Maertin Heating & Cooling to anyone!
Maertin Heating and Cooling is an Excellent company! When my hot water boiler was down they had a technician (Rich) on site in less than 2 hours. The repair was diagnosed and completed with 30 minutes. I was up and running immediately. I cannot say enough about the professional level of service this company…
Thank you Maertin Heating After losing both our heat and hot water with an unpreventable boiler system breakdown, we are so very grateful to the speed and efficiency of service Maertin Heating offered to restore our home’s operations to better than before! We are very impressed with the new system’s operation and…
Service has everything to do with who you choose for your heating and air-conditioning. Scott and his team are like family to us, they have come to the rescue quite a few times over the years. Scott has always gone out of his way to help us with advice, making adjustments, and servicing our HVAC systems.
Great, professional and efficient techs. Been using Maerten for years for home and business.
