How Much Does HVAC Cost in Denver?
For most homeowners in Denver, HVAC repairs typically range from $150 to $700, while full system installations generally fall between $3,500 and $7,500 depending on the equipment and specific home requirements. At Fireside Heating & Air Co., we provide upfront pricing on every job, meaning the price we quote is the price you pay, with no surprises or hidden fees after the work begins.
HVAC Cost Breakdown (2026)
We believe in straight talk about what things cost in the Denver market. Because we have served this community for over 8 years, we know that no two homes are exactly the same, but we can provide reliable ranges based on our experience with local systems.
| Service Type | Estimated Cost Range |
|---|---|
| AC Repair | $150 - $650 |
| Furnace Repair | $150 - $700 |
| AC Installation | $3,500 - $7,500 |
| Seasonal Tune-Up | $80 - $200 |
When you look at these numbers, keep in mind that the final cost of a repair often depends on the age of your system and the complexity of the part required. For instance, a simple capacitor replacement on a unit in a home in Park Hill will cost significantly less than a blower motor replacement on a high-efficiency system in a sprawling home in Cherry Creek. We always examine the unit, diagnose the specific issue, and present the cost before we turn a single wrench.
What Affects HVAC Pricing in Denver
Understanding why HVAC pricing varies helps you make better decisions for your home. We see these five factors influence costs most often in our daily work across the Denver metro area.
- Equipment Efficiency Ratings: Higher SEER2 ratings for air conditioners or AFUE ratings for furnaces carry a higher upfront cost but often lower the monthly utility bills. We help you balance the initial investment against long-term energy savings.
- System Capacity and Home Size: The square footage of your home and the quality of your insulation dictate the size of the unit you need. Installing a unit that is too large or too small for your home leads to inefficiency and premature wear.
- Ductwork Condition: In many of the older neighborhoods like Washington Park or Highlands, we often find original ductwork that requires modification or sealing to support a modern, high-efficiency system.
- Installation Complexity: Access to your equipment matters. If your furnace is tucked into a tight, unfinished crawlspace or a cramped closet, it requires more labor hours to safely remove the old unit and install the new one.
- Brand Specifications: We are trained to service and install nine major brands, including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Each brand has different pricing tiers and specific compatibility requirements.
If you are concerned about the cost of a repair, remember that we offer a free second opinion on any written estimate you have received from another company. If you aren’t sure if a repair is worth it, call us at (866) 561-3358 and we will give you an honest assessment.
How to Save on HVAC Costs
You do not need to overspend to keep your home comfortable throughout the changing Colorado seasons. We recommend focusing on maintenance rather than emergency fixes, which are almost always more expensive. A regular tune-up, which we offer for $89, can identify minor issues like a loose connection or a dirty flame sensor before they turn into a no-heat emergency at 2 a.m. in the middle of a blizzard.
We also keep our pricing fair and accessible for those who have supported us for decades. We offer a permanent 5% discount for seniors and veterans on all services. Additionally, if you have a repair job that exceeds $250, we offer $50 off the total. These small, consistent savings add up over the years and help keep your system running without breaking your budget.
Finally, avoid the temptation to delay service when you notice a change in how your system sounds or smells. A system that is struggling to start or making a grinding noise is putting extra strain on its components. Addressing these warning signs early usually costs much less than waiting for a complete system failure.
Safety and Professional Care
When dealing with your HVAC system, especially furnaces and gas-fired equipment, safety is the first priority. Because these systems involve high-voltage electricity and natural gas lines, we strongly advise against attempting internal repairs yourself. Attempting to bypass safety switches or working on gas valves without specialized training can lead to carbon monoxide leaks or fire hazards. Our technicians are background-checked, uniformed, and trained as journeymen to ensure every repair is done right the first time. We treat your home the way we would treat our own mother’s, which means we put on shoe covers, clean up after ourselves, and never leave a job site until it is safe and secure.
FAQs - HVAC Cost
How much does an AC tune-up cost in Denver?
A professional seasonal tune-up typically costs between $80 and $200. We currently offer a seasonal tune-up for $89, which includes a comprehensive check of your system’s electrical connections, refrigerant levels, and safety controls. Call (866) 561-3358 to schedule yours before the summer heat hits.
Is it cheaper to repair or replace an HVAC system?
If your system is under 10 years old and the repair cost is less than 50% of the value of the unit, a repair is usually the most cost-effective path. However, if you are constantly paying for repairs on a 15-year-old unit, replacing it with a modern, efficient model will save you money on utility bills and eliminate the stress of recurring breakdowns. We provide honest, upfront advice to help you decide which path makes the most sense for your specific situation.
Can you provide a quote over the phone?
While we can provide general pricing ranges for common services, we cannot give you an exact price for a repair or installation without seeing the specific equipment in your home. Every home is unique, and we pride ourselves on giving you a firm, written price before we start work. Call (866) 561-3358 and we will send a technician to your home to assess the situation and provide a no-hassle quote.
Do you offer emergency service for no-heat situations?
Yes, we answer our phones with a live person 24 hours a day, 7 days a week, including weekends and holidays. Whether it is 2 a.m. on a Tuesday or the middle of Christmas dinner, we are available to help you when your furnace stops working. We understand that a lack of heat in a Denver winter is a serious matter, and we prioritize these calls to keep your home safe.
What does the 90-Day Done Right Promise cover?
Our 90-Day Done Right Promise means that if a repair we performed fails within 90 days, we will come back and make it right at no additional cost to you. We stand behind our work in writing, with no paperwork and no arguing, because we believe in taking responsibility for the work we do in your home.

What Our Customers Say
"System is running well again and the price was in line with the other quote I got. The arrival window was four hours wide and he came at the very end of it, so plan your day around that."
- Simone Dawson"The drain line was clogged and the safety switch had shut the whole system down. He cleared it, flushed it, and fitted a proper cleanout so I can pour vinegar through it myself once a season."
- Terrence Coleman"The work was done properly. I did have to follow up twice to get the invoice and the warranty details emailed over. The repair itself has been trouble free."
