Monument Furnace Repair & Replacement

Monument’s elevation means your furnace operates with significantly less oxygen than it was designed for at standard atmospheric pressure. A furnace not adjusted for Monument’s altitude burns fuel less completely, produces more CO, and works harder than it should. WireNut treats altitude tuning as mandatory on every Monument furnace job.

Furnace Repair and Replacement for Monument Homes

Monument’s elevation of around 7,000 feet means your furnace operates with significantly less oxygen than it was designed for at standard atmospheric pressure. A furnace that has not been adjusted for Monument’s altitude burns its fuel less completely, produces more carbon monoxide as a combustion byproduct, and has to run longer to generate the same heat output. The practical effects show up as higher gas bills, reduced comfort on Monument’s coldest nights, and accelerated wear on burner components working harder than they should.

If your furnace situation involves a repair rather than replacement, our heating repair service covers the full diagnostic and repair process. For Monument homeowners with boiler heating systems, our boilers page covers what WireNut handles for hydronic heating. See the full Monument HVAC services page for everything we offer.

Furnace Issues WireNut Handles in Monument Homes

  • Furnaces that will not ignite or stay lit, caused by failed igniters, faulty flame sensors, or gas valve issues that need proper altitude-adjusted diagnosis.
  • Furnaces that run but produce insufficient heat for Monument’s cold nights, often caused by improper altitude commissioning, a dirty heat exchanger, or a failed heating element.
  • Limit switches that trip repeatedly, indicating the furnace is overheating from restricted airflow, a dirty filter, or a failing component.
  • Cracked heat exchangers that allow combustion gases including CO to mix with the heated air circulated through the home, which is a safety issue that warrants immediate attention at Monument’s elevation.
  • Aging furnaces more than 15 to 20 years old where the cost of continued repair is approaching or exceeding what replacement would cost over the same period.

Here are the furnace situations our Monument HVAC technicians see most often.

A furnace that is more than 15 to 20 years old, has a cracked heat exchanger, has needed multiple repairs in recent heating seasons, or cannot keep your Monument home comfortable during Front Range cold snaps is a replacement candidate. WireNut gives you an honest assessment without pressure and tells you what we find.

Sharing an amazing experience from WireNut on my wife's account. Brady Ross was exceptional from start to finish! Brady showed up with dynamic expertise, a great personality and a bodybuilder 's physique. He thoroughly cured any deficiencies concerning my furnace even training me on the ins and outs while providing me a truthful assessment of it's condition. He even took out the used filter when he left. Thank you, Brady! You are the man.

The electrician, who came out to my house to fix an issue. His name was Jarred, he was amazing. He was super friendly, very clear on explaining everything to me, he was also very efficient, explained all of my options and what may need to be done coming up. there was no pressure, he it was very professional, he did a great job and wire nut is very lucky to have him on their team. That review was from June. I also had work done today, with a different electrician from WireNut, his name was also Jared. He was also professional, super friendly and also very informative, explaining information in an understandable way. It is great that WireNut can send different electricians and the same high quality service and interactions are received. I appreciate the work, the information and the excellent customer service both of these men gave.

Very professional, courteous and prompt. Was able to get my repair done and water back on within a 1/2 hour. Had to have an emergency call out as I needed the water back on asap, so I was ok with that fee. The cost for the repair was very high as compared to buying the parts and doing it myself. I just didn’t have time or the specialty tools to do it myself. All this being said, I would highly recommend them based on their quality of work and great service.
