    Fast response to a furnace that didn't want to stay lit. Fixed quickly and reasonably priced for short notice. Efficiency first says it all!

    BEWARE!! DO NOT use or suggest anyone too this company especially the owner Mike he is dishonest…read more This is why I scheduled an appointment for a tuneup/clean up of furnace as well as an inspection of the furnace heater because it wasn't properly turning on Mike the owner stated that my six year old furnace "warranty expired" comes too find he stated my new furnace needed $1500 "in repairs that were needed" to fix he "faulty" furnace. So I payed Mike the owner $125 for the so called "tuneup" and "inspection" job and he went on his way. The next day I called a second company too get a second opinion and comes too find out they told me there was no tuneup done too the furnace at ALL!! Even though I paid Mike the previous day to do so. And that's NOT ALL. The "repairs" mike the owner suggested were "necessary" were false and dishonest according to the other company Terry and Nancy HVAC. So I had to pay a second time to get the job inspected and tuned up right this time. Comes to find out a heat sensor was blocked from the built up of dust that was blocking the heater from turning on which I paid the owner Mike too do so and didn't. The second company also pointed out my furnace had a ten year warranty. But according to Mike it only had a six year warranty that just "expired" which was also dishonest of Mike. Therefore when I tried calling him to confront him twice about this. He would immediately hang up on me. So please do not trust climate design Inc With your furnace needs unless you're willing to deal with untrustworthy behavior and Crooked work of the of this so called "business owner" Mike.

He came over the next morning, in a heavy snowstorm (thank you Mike!) and was able to find and fix the issue immediately. Mike is awesome. He is the owner of the company, and very knowledgable.

    Absolutely Stellar Experience with MJ Heating & Air - A Family-Owned Gem!…read more I recently had the absolute pleasure of working with MJ Heating & Air, a family-owned business based in Colorado Springs, and I can honestly say they exceeded every expectation I had - and then some! If you're in need of HVAC or heating services, stop searching now and give them a call. Trust me, you will not regret it. My heating issue seemed like a simple fix, but it quickly became apparent that it was more complex than expected. Thankfully, Jeremy and his father, who run this incredible business, were up for the challenge. These two didn't just come in, do the bare minimum, and leave; they went above and beyond to ensure my home was not only comfortable but that the system was running perfectly. The level of attention to detail they showed is something you rarely find these days. From the moment they arrived, I knew I was in good hands. They were professional yet personable, maintaining the perfect balance between warmth and expertise. They took the time to explain everything they were doing and never made me feel rushed or like just another job on their list. What truly set them apart was how comfortable they made me feel - not just with the work they were doing, but also in terms of their presence in my home. I felt entirely safe and at ease having them around my family, which is so important when inviting service professionals into your personal space. Jeremy and his father didn't just treat this as a job; they treated it as an opportunity to build trust and deliver exceptional service. It's clear they take immense pride in their work and in the relationships they build with their customers. You could tell they weren't satisfied until everything was just right, and they left my home feeling more like trusted friends than just HVAC technicians. In a world where so many companies cut corners and rush through jobs, MJ Heating & Air stands out as a beacon of what great service should be. They embody professionalism, reliability, and, most importantly, genuine care for their customers. I have no doubt that anyone who hires them will feel the same way. Fellow Coloradans, if you need HVAC or heating services, do yourself a favor and reach out to MJ Heating & Air. You will not only receive top-notch service but also peace of mind knowing your home is in the best hands. They have my highest recommendation, and I'll be a loyal customer for years to come!
