Honest advice
Repair or replace? Here’s how we decide.
Nobody wants to buy a furnace they did not need, or keep pouring money into one that is done. This is the same thinking Dan walks customers through at the kitchen table.
Four questions that settle it
Is it safe?
A cracked heat exchanger can leak carbon monoxide into your home. When we find one on an older furnace, replacement is almost always the right answer. Safety comes before cost every time.
How old is it?
Under about ten years, most repairs are worth doing. Past fifteen on a furnace, or past twelve on an air conditioner, we look harder at what the repair buys you.
What does the repair cost compared with the system’s value?
A common rule of thumb: if the repair costs more than about half of a new system and the equipment is in the back half of its life, replacement starts to make more sense. An igniter or capacitor on an old furnace is still usually worth fixing.
How much is it costing you to run?
Rising gas and electric bills, rooms that never get comfortable and repeat breakdowns all count. Today’s high-efficiency furnaces and heat pumps can cut those bills, and that belongs in the math.
What you get from us either way
- A clear explanation of what failed, in plain language
- The repair price before any work starts. Repairs are only made with your approval.
- A free estimate on a replacement if one is worth considering, so you can compare side by side

Customers who have been with us for ten and twenty years say the same thing in their reviews: honest estimates and fair pricing. That reputation is worth more to us than any single sale.
If it is time to replace
We install high-efficiency Rheem furnaces, air conditioners and heat pumps, and size every system to your house rather than to the last one that was there.

Great air conditioning process and execution. Showed up, assessed, and priced. No “cooling associate” follow-up needed like 2 other companies; this company cut to the chase. They gave the most competitive price and Charlie and Ian were thorough and worked hard on my install. Highly recommend.

What an amazing and honest technician Sam was. He was very knowledgeable and thorough. Sam took his time and checked our furnace and AC/Heat-pump top to bottom. He put on shoe covers each time he came into our house. I will never use any other company to service our system. You need an honest and reliable company call Aspen Creek Heating and Air. Sam thank you for all you did.

Really friendly, considerate people and great work from start to finish—scheduling an estimate all the way through installation. They explained everything and really showed that they cared about my questions and my satisfaction. Our new heat pump and furnace are great.

Sam was professional and knowledgeable about my A/C & furnace. He patiently address all my questions. I understand that state of my equipment better and have expectations for when additional services and replacements are likely needed.

Very satisfied with our experience with Aspen Creek. Sam came out to evaluate our A/C system after another company in the area told us we needed a replacement part that would cost thousands of dollars. Sam took the time to thoroughly assess the system and let us know that the part was actually functioning properly and did not need to be replaced. He also gave us some helpful recommendations for improvements that could genuinely make a difference with our A/C performance, while being clear that they weren’t urgent or things we needed to spend money on immediately. We really appreciated his honesty, expertise, and straightforward approach. It was refreshing to work with someone we felt we could trust.

I can not say enough about my positive experience with Aspen Creek and the installation of my heat pump to replace my very old A/C. From the office staff Shannon and Danni helping me with my scheduling conflicts, to Sam giving my estimate and answering questions, and Charlie, Toby and Trevor coordinating the install, everyone was knowledgeable, professional, and friendly. Trevor was my HERO and made sure I understood my new system, showed me how to work everything and told me some things to watch for. It feels good knowing things were done correctly and I feel confident should I have any questions or issues, I am in good hands! Thank you Aspen Creek, I'll sleep well tonight in my cool house! 🤣
Questions we hear a lot
How long does a furnace last in Colorado?
A well-maintained gas furnace often lasts 15 to 20 years, and some go longer. Air conditioners and heat pumps are usually closer to 10 to 15. Annual maintenance makes a real difference to both numbers.
Will you try to sell me a new system?
No. Several of our reviews come from people who called us for a second opinion after another company’s quote. If a repair makes sense, we will say so. If it does not, we will explain why.
Do you give free estimates on new equipment?
Yes. Estimates for a new furnace, air conditioner, heat pump or mini-split are free.
Are there rebates on new equipment?
Often, yes. Xcel Energy offers rebates on qualifying high-efficiency equipment, and programs change from year to year. We will tell you what applies when we write your estimate, and we can help with the paperwork.
Not sure what to do with an old system?
