  Nixon is smart and quick and honest and kind. He did exactly what he said he would do and quickly assessed the issue and knew exactly how to fix it. His pricing is great and I will use him every time. Best AC company I have found. Hands down.

  Our 2 mini-split units received their annual services today. Nixon arrived early for the service appointment. Before beginning his tune-up/cleaning, he asked if there were any issues that should be addressed during the visit. I mentioned an issue that occurred during the heating season. Both units(exterior washed/interior units checked for drainage and issues) were given a clean bill of health. Due to a leaking cooling line cap last year, there was a need for additional cooling material. Visit was punctual, friendly and professional. We even discussed setting up a twice a year maintenance schedule being proactive.

  Company owner Nixon was extremely knowledgeable and was able to explain things such that even I could understand it. He and his staffer Zeke were efficient and courteous. His price quote stayed the same from start to finish and work was done under the time estimate. I am 1000% pleased and will now use his company for routine maintenance.

  The big fear when hiring an hvac contractor is that the service technician is looking for every opportunity to upsell or replace a furnace or ac unit. At least, I feel this way. But, what I experienced with Firestone was straight forward and honest.  Instead of upselling, Nixon quickly determined where to look for the problem and then he fixed it.   Easy peasy.  Firestone over delivered.  I will call them again when I need my hvac serviced again.

  We had a second HVAC unit installed in our large home.  It was built with only a single unit which struggled to heat and cool the second floor.  It was a big project, but service and installation went smooth.

  We had great service, prompt estimate by the owner named Nixon, and a good price. Very friendly, no pushy sales, gave us three options and actually took less time than expected! Highly recommend this company owned by Nixon. Oh, and Nixon comes on site to ensure quality work at each appointment!

  I've had Nixon from Fireside Heating & Cooling over to our house twice in the last week (two separate issues) and he's been nothing but professional.  He quickly identified the issue both times and either repaired or advised on the best course of action.   Most importantly for me, he explained what was going on, how to prevent it in the feature and didn't try to scare us with "this is going to be a huge problem - you need to spend a large amount of money or replace your furnace and AC right now", like we so often here.

He was very pragmatic in his approach and its clear he's trying to win customers the right way, through great customer service, transparency, and being fair.

Frequently Asked Questions

How do I know if my furnace needs immediate repair?

If your furnace isn’t producing heat, is making unusual noises, or is cycling frequently, it’s best to schedule a professional inspection as soon as possible.

What factors determine whether I should replace my furnace?

Age, repair frequency, rising energy costs, and inconsistent heating are all indicators that replacement may be the better long-term option.

How long does a furnace installation take?

Most installations can be completed in one day, though more complex setups may require additional time.

Can regular maintenance really prevent breakdowns?

Yes. Annual maintenance helps identify worn components early, reducing the likelihood of unexpected failures during peak winter use.

What type of furnace is best for Denver homes?

The ideal system depends on your home size, insulation, and heating needs. High-efficiency gas furnaces are a popular choice for Denver’s colder climate.
