Annual Maintenance

There is nothing better for your heating and/or air conditioning system than annual maintenance. Annual maintenance allows your system to work at peak efficiency year in and year out. A system that is maintained annually experiences considerably fewer breakdowns.

This virtually eliminates the need for you to pay for costly repairs. You'll enjoy the peace of mind in knowing that your system is saving you money on your utility bills every time it comes on. In some instances, the energy savings are enough to pay the cost of the planned annual maintenance service.

  • I would recommend this business

Front Range Mechanical deserve more than 5 stars. We called for a second opinion when we were told our A/C unit needed to be replaced. Brad came out and did a few adjustments and the knocking noise stopped completely. He was super thorough and checked everything. He didn’t even charge us for coming out. We will be calling them again, when we need them again!

Customer Testimonials

Front Range Mechanical Services (FRMS) is a great HVAC company. The owner, Stephen Korff is extremely knowledgeable (sometimes answering questions before you ask them), professional, courteous, and no hard sell. The price from FRMS was fair, and they handle all the paperwork for the Excel rebates. We had a new gas furnace and AC installed this past Monday. In addition to the HVAC crew also being knowledgeable, professional, and courteous, they were also careful of our house and furnishings, and cleaned up when done - hardly knew they were here after they left. If you are getting estimates from multiple HVAC contractors, make sure FRMS is on your list.

Stephen and his crew are some of the best folks we've ever worked with. They are honest, prompt, polite and more than willing to educate you on your service/products. I would highly recommend them to anyone looking to get work done! Thank you guys!

I checked out many companies (including the Home Depot contractors) and prices when my water heater went out. Steve's price was very reasonable and his customer service was great. He returned calls, emails, and kept the schedule he said he was going to keep. Don't get a water heater installed until you get a quote from him. I'm a stickler and have never endorsed a services company but felt compelled to do so with Front Range Mechanical.

Very professional technicians, took care with the house and made sure the surroundings were cleaned up properly.

Steve and everyone at Front Range Mechanical are amazing. Not only did he drop everything to help us out after a furnace fire, he loaned space heaters to us while restoration & construction was happening and our furnace was out of commission. Steve even picked up the space heaters when we were finished with them. He did an incredible amount of research and we learned that our furnace was too big, and therefore inefficient, for our home size. He notified us that we were eligible for a rebate from Xcel Energy. Hands down, the smoothest, most educational and most professional company we have worked with in a while. I highly recommend Front Range, if you're looking for furnace/air conditioning help.

Five stars for sure. My 92-year-old mother's air conditioner stopped working over the weekend I reached out to Front Range Mechanical Hvac's and they were able to send a technician out first thing this morning. It was a simple fix to the system. The staff was awesome responsive friendly and knew actually what they were doing. They are a fair company and somebody you can trust to not take advantage of you. Thumbs up

We woke up to no heat this morning. I messaged everyone I knew and a friend referred us to Front Range. Dominick was sent out to us and he arrived within a few hours which was perfect for us. As well as fixing our problem he took the time to clean dust and debris out of our furnace and it now works better than ever. The price was very reasonable for the service we received. He was very thorough and a pleasant fellow who enjoyed the kids and the dogs at our home. I feel he went the extra mile to make sure we were satisfied. They have earned our business and we will happily use them again if the need arises.
