Fox Valley HVAC Service

My boiler was not working properly and Marten's got me in right away. A part had to be ordered and Jeremiah made it a point to look up my maintenance schedule so he could save me an extra visit. Always top-notch, friendly and efficient service! I'd highly recommend Marten's to anyone.

Marten’s installed a new furnace about 5 years ago and did an amazing job. This call was just for a standard maintenance before winter. Appointment communication was excellent (email confirmation, text reminder and when on their way) Ryan was our service person - he was on time, did great work, gave advice for future care and clean-up. (Also great with dog who checked on him while working) - Long story short, from an install to maintenance they’ve been great to work with!

Martens Heating installed a brand new boiler system in my mother's 58 year old house. They also updated all the thermostats.
They did an excellent job: clear communication, showed up everyday, went above and beyond in making sure the advanced system worked perfectly.
Thank you Martens!

Called Martens to find out if they could investigate a heating duct issue. The service tech was professional and honest; gave me a range of options for how to address the problem. Haven't had any actual work done yet but the initial meeting was very good. Once I receive a service estimate, I will use them to get the work done rather than going elsewhere.

We have needed them a few times over the last few years. And it always an emergency situation. Our heat went out in the middle of winter and just recently our air went out in the middle of summer. They always take such good care of us. Super responsive. Very knowledgeable and explain things very well. If you end up in a situation where you need someone ASAP this is the place to call…hands down! Customer service, pricing, quality are all top notch! Thanks guys! We really didn’t want to have no air conditioning for the rest of summer- lol!

Very professional and knowledgeable. Great job! I would not hesitate to recommend Marten’s for any HVAC work needed

My indirect water heater was set so that my shower was too hot and I couldn’t get it any cooler. They turned down the temperature and hope that fixes the issue. Martens is a great business and are wonderful to work with. I am a new customer and will continue to use them for my heating needs. I’ll also “spread the word” about how great they are! Thank you!!

They arrive on time and get right to work. Seem to be well trained and keep good records of our systems. Glad I’ve found them.

Our AC went out when it was mid 90s outside. We called Martens and they were able to stop for a repair the next morning up the crack of dawn. They were polite, competent and professional. DON’T tell Martens I said this, but their rates were 1/3 to 1/2 LESS than what I was expecting. Great job, Martens!

Prompt professional service. Best prices in area. You won't be disappointed.

A/C unit required removal prior to landscaping work.
Due to short notice by the landscape team being available to start the project the next day the A/C unit needed to be disconnected and removed ASAP. The staff at Martens Heating and Cooling rescheduled one of their technicians and within a few hours the technician arrived and performed needed work.
Technician was professional, friendly and competent. Work was completed by the very cooperative Martens team for which we are very grateful.

Jason was so helpful, we wouldn’t trust anyone else- he is truly the best!

Technician was kind enough to take the time to explain everything to me and answer all of my questions. The contact leading up to the appointment was great. Martens even bent me up a custom range hood so I can brew beer in my garage. Would highly recommend.
