“Furnace quit on a -5°F night in Littleton. Summit's emergency tech arrived in under 2 hours, diagnosed a failed igniter, and had heat running again before midnight. Incredible response.”

“Installed a dual-fuel heat pump system in our Aurora home. Works as AC in summer and efficient heat pump in fall/spring, with the gas furnace kicking in only on the coldest days. Bills dropped significantly.”

Our Approach

HVAC Installation in Denver

Denver's extreme temperature swings — from 90°F summers to -10°F winter nights — demand HVAC systems that perform reliably year-round. Altitude also affects system performance, requiring technicians who understand the adjustments needed for proper combustion and airflow at 5,280 feet.

HVAC system design for Denver homes must solve for two distinctly different climate challenges that few other markets impose simultaneously: genuine summer heat requiring real cooling capacity, and genuine winter cold requiring high-performance heating down to -10°F or below. The altitude overlay — 5,280 feet — adds a third dimension that affects both cooling and heating system performance and must be reflected in every aspect of equipment selection and installation. For the cooling side, Denver's elevation requires equipment de-rating acknowledgment in the Manual J load calculation and equipment selection. A 3-ton condenser rated at sea level produces slightly less than 3 tons of cooling capacity at Denver's altitude due to the reduced air density at the condenser. Summit Climate Solutions accounts for this in every installation calculation for Littleton, Aurora, and Lakewood homes, ensuring that the delivered cooling capacity matches the load rather than the nameplate rating. The heating design question for Denver is increasingly answered by dual-fuel heat pump systems. Standard heat pumps lose efficiency rapidly below 35–40°F as the outdoor air becomes too cold for efficient heat extraction — a significant limitation in a market where temperatures regularly drop below that threshold. Cold-climate heat pump technology has advanced to allow operation down to -13°F with useful efficiency, but the most practical solution for many Denver homes is a dual-fuel system: a heat pump that provides efficient heating and cooling during the shoulder months and mild winter days, automatically switching to a high-AFUE gas furnace when temperatures drop below the heat pump's efficient operating range. Aurora and Lakewood homeowners using dual-fuel systems consistently report significant natural gas savings compared to furnace-only heating without sacrificing comfort during the coldest Denver nights. Duct system performance in Denver is affected by the wide indoor-outdoor temperature differential during heating season. A system delivering 130°F supply air through ductwork running through an unconditioned crawl space at 10°F experiences substantial heat loss, and duct insulation levels appropriate for mild climates are insufficient for Denver's heating conditions. Summit's installation assessments for Denver homes include duct condition and insulation evaluation, with duct sealing and re-insulation frequently part of the recommended scope for older Aurora and Littleton homes.

HVAC installation is one of the largest home improvement investments most families make, and the industry is rife with oversizing, brand upsells, and opaque equipment margins. Summit Climate Solutions builds every installation quote around a room-by-room Manual J load calculation — the ACCA-standard method for determining the actual heating and cooling load of your home. This prevents the chronic oversizing that plagues contractor-installed systems, which short-cycle, wear out faster, and fail to dehumidify properly. We present equipment options at multiple price points with honest payback analysis for higher-efficiency units, and we partner with financing programs that offer 0% promotional periods so the investment is accessible regardless of upfront budget.

Every installation includes a Manual J load calculation and a post-install commissioning report — documented proof that your system is correctly sized, charged, and airflow-balanced for maximum efficiency and comfort.

Problems We Solve

  1. Oversized systems installed without a Manual J calculation short-cycle and fail to control humidity

  2. Equipment markups vary wildly between contractors — the same unit can cost $800–$1,500 more from one company vs. another

  3. High-efficiency upsells don't always pencil out financially — the payback period on a 20+ SEER unit can exceed 12 years

  4. Installation quality matters as much as equipment quality — improper refrigerant charge voids manufacturer warranties

  5. Ductwork issues absorb 20–30% of system capacity — a new unit on a leaky duct system performs like a used one

  6. An aging HVAC system over 12 years old consumes 30–50% more electricity than modern high-efficiency units, quietly adding hundreds of dollars to your utility bill every year while delivering inconsistent comfort.

  7. Uneven temperatures between rooms — too hot upstairs, too cold downstairs — often indicate an undersized or improperly designed system that no amount of maintenance will permanently resolve.

  8. Refrigerant phase-outs mean that systems running R-22 are becoming increasingly expensive to service as refrigerant prices climb; replacing with an R-410A or R-32 system eliminates this ongoing cost exposure.

Frequently Asked Questions

8 answered
How much does a new HVAC system cost installed?

Total installed costs vary significantly by system type, size, and efficiency tier. A standard split system (AC + air handler or furnace) for a 1,500–2,500 sq ft home typically ranges from $6,000–$12,000 installed. Heat pump systems range from $7,000–$15,000. High-efficiency variable-speed inverter systems run $12,000–$20,000+. We provide itemized quotes so you can see exactly what you're paying for equipment vs. labor vs. materials.

What is a Manual J calculation and why does it matter for pricing?

A Manual J is the industry-standard room-by-room heat gain and heat loss calculation required by most building codes. It determines the exact system size your home needs. Skipping it and guessing leads to oversizing — which increases upfront cost for equipment you don't need, and leads to short-cycling that accelerates wear and reduces efficiency. We perform Manual J on every installation quote at no additional charge.

Is a higher SEER2 rating worth the extra cost?

It depends on your usage and utility rates. A 16 SEER2 vs. 14 SEER2 unit might save $150–$250 per year in a hot climate like Phoenix — the $600–$1,000 price premium pays back in 3–6 years. A 20+ SEER2 inverter system costs $3,000–$5,000 more than a standard unit and has a 10–15 year payback in most markets. We model the actual dollar savings so you can make a rational decision.

What financing options are available for HVAC installation?

We offer multiple financing options through HVAC-specific lending partners: 0% interest for 12–18 months for qualified buyers, extended 60–84 month terms at competitive rates for larger jobs, and same-day approval decisions. Monthly payments on a $10,000 system at 7.9% over 60 months are approximately $202 per month — often less than the energy savings from replacing an aging inefficient system.

Does the installation price include removing the old equipment?

Yes. Our installation quotes include removal and legal disposal of the existing equipment, all refrigerant handling per EPA regulations, installation permits where required by local building departments, commissioning (refrigerant charge verification, airflow measurement, thermostat programming), and post-installation walkthrough. There are no hidden add-ons at the end of the job.

How much does a new HVAC system cost installed?

A new central AC runs $4,500–$8,000 installed. A full furnace and AC combination is $6,500–$12,000. Heat pump systems range $5,500–$14,000 depending on efficiency. Every quote is itemized with equipment, labor, and permit costs broken out separately.

Can I get financing for a new HVAC system?

Yes. We offer multiple financing options including 0% interest for 18 months, and longer-term plans at competitive rates for larger investments. We can usually get you a credit decision within minutes during your estimate appointment.

Will a new HVAC system really lower my energy bills?

Modern 16–18 SEER2 systems use 30–50% less electricity than a 10-year-old 10 SEER system. Most homeowners recoup the efficiency premium in 4–7 years through energy savings, and enjoy improved comfort and lower maintenance costs throughout the system's 15–20 year life.
