Maertin Heating & Cooling for HVAC system maintenance

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…
I was very pleased with the service of Maertin Heating. Techs were professional and courteous. Would recommend them.
Always reliable and professional!
Very diligent service! Always take the time to explain a issue and talk about the fix! No surprises!! Great company, great service
I woke up with the temperature in my house at 66 degrees. I called Maertin Heating & Cooling and Jani recommended checking the filter first. I set up a schedule to have my furnace tuned up anyway since it had not been done in years. My technician was Cristian and he was so pleasant and knowledgeable. In getting…
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…
Scott was very thorough with options when deciding on system. Explained everything again after install. The techs rocked out the install even on this cold day. Thanks again Scott and your staff. Even the girls in the office followed up!
The Maertin group is highly trained, responsive to my requests for service and pleasant to deal with.
Excellent professional service!
I've used Maertin Heating for many years. They are friendly, knowledgeable people who are just a pleasure to work with. They are good at what they do and it shows.
Problem diagnosed and solved with reasonable cost
Brett H was awesome and very friendly and knowledgeable. A++
I can’t rave enough about how great they are. From customer service and follow up they are the best. Support local businesses!
Brett was fantastic! Hardworking, friendly, and efficient. Highly would recommend!
Great tech that came to my home! Explained everything and answered several questions I had! Maertin came out quickly and will be a repeat customer!!!
Excellent service! We have used Maertin multiple times for our small business and home. They are professional, efficient and fair. I would highly recommend them!
Very easy experience from start to finish. Very professional team.
Brett was on time, friendly and extremely efficient. He explained fully what he did. I would definitely recommend Maertin heating and Cooling.
Our home is 25 years old and we had Maertin replace our air conditioner and HVAC. They also have done work at my son and daughters houses and they always do a great job and we appreciate their service.
Never disappointed with their service. They have the most helpful and professional staff with the utmost integrity. I will always give them my business.
They are fantastic!! I couldn’t be happier or satisfied with their work. Always outstanding!
As always a great experience !
Maertin has been our heating and cooling provider for many years and they do a fantastic job. I would highly recommend them.
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!
Paul is the best HVAC tech in the South Suburbs! I have been struggling with the issue of very cold air in my basement and family room for years with high temps in my upstairs bedrooms since I moved in my house over 30 years ago! Paul showed me how dampers work and never knew I had them and no tech has ever…
As usual, great service from Maertin. Rob was very thorough performing his maintenance checks. I would use no other HVAC or heating service. Maertin is the best as is their technicians. Maertin rocks!
We have used Maertin several times now and have been happy with the communication, service, and professionalism. Would recommend them to anyone looking for service
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.
Always professional and informative. Will continue to rely on Maertin for all our heating and air conditioning needs
Prompt,helpful,curteous
I have used this company for many years and I am completely satisified with their excellent customer service and relations, on time for call, highly knowledgably about my system and its history!
Highly recommended! Polite and professional service
We had Maertin out to do a HVAC tune-up for winter. Paul W was great!! He was on time, showed me things to look out for, and discussed the pros and cons of my unit. The thing I really like was how all of my neighbors said the companies they used were in and out in 20 minutes. He was here for well over an hour and…
