Accepted Answer

A typical installation takes 4-8 hours for a standard replacement and 1-2 days for heat pump or mini-split systems. Our team protects your home with drop cloths and shoe covers, handles all equipment removal and disposal, and walks you through the new system before leaving.

Question 8

My furnace is not heating. What should I check?

Accepted Answer

Follow these troubleshooting steps: Make sure heating is turned on in the thermostat. Check to see if the furnace blower is running (air coming out of the vents). Check to see if the indoor AC coil (on top of the furnace) is leaking or freezing. Based on your findings, you can determine next steps.

Question 9

Why is my furnace short cycling (constant on/off)?

Accepted Answer

The number one reason for short cycling is a dirty filter, which will damage the furnace and its sensors over time. Change the air filter first. If that doesn't fix it, the issue is likely a faulty flame sensor, thermostat, or blower motor.

Question 10

My furnace is making strange noises. Is that normal?

Accepted Answer

Minor humming is normal, but unusual sounds may indicate problems. Buzzing may mean the blower motor or inducer draft motor is failing. Loud bangs and vibrations typically indicate wheel assembly or blower motor failure. Keep the system off until inspected. Note that ductwork expanding and contracting with temperature changes is common in Colorado winters.

Question 11

There's water or a leak near my furnace. What's causing it?

Accepted Answer

Leaks happen for several reasons: indoor coil freezing (caused by a dirty filter or malfunctioning AC unit), drain pipe failure or misalignment, or condensate pump failure. Condensate pumps typically need replacement every 3-5 years. Investigate the origin of the leak to determine next steps.

Question 12

How much does a new furnace cost in Denver?

Accepted Answer

Furnace installation in Denver typically ranges from $5,310 to $7,520 for a standard gas furnace, with the full range being $4,200-$9,800 depending on efficiency, brand, and home size. High-efficiency models (95%+ AFUE) cost more upfront but reduce heating bills by 15-20%.

Question 13

When should I replace my furnace instead of repairing it?

Accepted Answer

Consider replacement if your furnace is 15-20+ years old, requires frequent repairs, has a cracked heat exchanger, or still uses a standing pilot light. Modern furnaces are significantly more efficient. Upgrading from an 80% AFUE to a 95%+ AFUE unit can reduce heating costs by 15-20%.

Question 14

What are signs my furnace needs attention?

Accepted Answer

Common signs include unusual noises, uneven heating, frequent cycling, increased energy bills, and a yellow or flickering pilot light. These symptoms help you understand when your system may be struggling.

Question 15

My AC is not cooling. What should I check?

Accepted Answer

Start with these steps: Make sure cooling is turned on in the thermostat. Check if the furnace blower is running (air coming out of vents). Check if the indoor AC coil on top of the furnace is leaking or freezing. Check if the outdoor condensing unit is running. These checks help identify the problem.

Question 16

My AC is freezing or leaking. What should I do?

Accepted Answer

Freezing is usually caused by a dirty air filter, low refrigerant, or a malfunctioning compressor. Start by changing the filter. If it was dirty, turn off cooling and run the fan only for 12-24 hours to de-thaw. If that doesn't fix it, the issue is likely low refrigerant or a failing compressor.

Question 17

The outdoor AC unit is not turning on. What's wrong?

Accepted Answer

Check the AC breaker in your electrical panel first. Listen for any noises from the unit when it's supposed to be running. If it's silent, the issue is likely a failed capacitor, contactor, or melted wiring, which are common problems caused by power outages, surges, dirty filters, or overwork.

Question 18

What's the deal with R22 refrigerant?

Accepted Answer

R22 was banned from production and importation by the EPA as of January 1, 2021 due to ozone depletion. R22 is now 4-8x the price of modern R410A refrigerant. UniColorado does not recharge leaking R22 systems because leaks grow over time, sealants only work temporarily, and brazing repairs are cost-prohibitive. If your system uses R22, it's time to consider a replacement.

Question 19

How much does AC installation cost in Denver?

Accepted Answer

Central AC installation in Denver typically costs $7,450-$9,122 on average for a 3-ton, 16 SEER2 system, with the full range being $5,400-$11,200 depending on efficiency and tonnage. Higher SEER2 ratings (18+) cost more upfront but reduce cooling bills by 20-30%.

Question 20

When should I replace my AC unit?

Accepted Answer

Most AC units last 15-20 years. Consider replacement if your unit is 15+ years old, needs frequent repairs, uses R-22 refrigerant, or your energy bills are rising despite maintenance. A new system with a higher SEER2 rating can significantly reduce your cooling costs.

Question 21

Do I need a new thermostat with a new AC?

Accepted Answer

While not always required, we recommend upgrading to a smart thermostat when installing a new system. It maximizes efficiency and can qualify for additional rebates from Xcel Energy.

Question 22

What is a heat pump?

Accepted Answer

A heat pump is an AC unit that can also absorb heat from the outside using electricity, providing both cooling in summer and heating in winter in one system. Unlike furnaces that generate heat by burning gas, heat pumps move heat, making them significantly more energy efficient.

Question 23

Do heat pumps work in Colorado's cold climate?

Accepted Answer

Yes. Cold-climate models from Bosch, Carrier, and Mitsubishi operate down to -13 to -23°F depending on brand. Denver averages just 2-4 days per year below 0°F. During the December 2022 polar vortex (-15°F), properly installed systems held homes at 68-69°F without backup heat. The critical factors: equipment rated for cold climates, a Manual J load calculation, and an installer who specializes in heat pumps.

Question 24

What type of heat pump is best for me?

Accepted Answer

If you have a gas furnace and AC with existing ductwork, the best option is a dual fuel air source heat pump using your existing ducts. If you don't have a central system or ductwork, mini-splits are often the most cost-effective solution.

Question 25

What's the difference between air source and mini-split heat pumps?

Accepted Answer

Air source heat pumps are typically retrofitted to existing forced-air gas furnaces in houses that have ductwork. They require ductwork. Mini-split heat pumps are installed in homes with no ductwork or central system. Mini-split indoor units can be installed on walls or floors and do not require ductwork.

Question 26

What's the difference between dual fuel and cold climate heat pumps?

Accepted Answer

Dual fuel heat pumps use a gas furnace as backup. The heat pump generates heat down to about 30°F, then the furnace takes over. Cold climate heat pumps use an electric furnace or air handler, are usually 18 SEER+, and generate heat down to 0°F to -13°F. Below that, the electric backup kicks in.

Question 27

Heat pump vs furnace: which is better?

Accepted Answer

Heat pumps provide both heating and cooling in one system, are more energy efficient, and qualify for more rebates. Furnaces heat faster in extreme cold. Many Denver homeowners choose a dual-fuel setup that combines both. The best choice depends on your home, budget, and preferences.

Question 28

What is a mini-split?

Accepted Answer

A mini-split is a ductless HVAC system consisting of one or more indoor units and an outdoor condenser. Indoor units come in wall-mount (most common), floor-mount, ceiling cassette, and ducted air handler varieties. Mini-splits are ideal for homes without existing ductwork.

Question 29

Can you install a mini-split I bought online?

Accepted Answer

No. We do not provide labor-only installations. Many units sold online are 'China-Split' rebrands that fail within 1-2 years, or grey market overstock without US warranty support. Mini-splits are complex systems that require proper installation. We specialize in Mitsubishi Diamond Dealer units with 12-year manufacturer warranty.

Question 30

Do mini-splits do both heating and cooling?

Accepted Answer

There are three varieties: Cooling Only (single-zone cooling), Heating + Cooling (cooling and heating down to about 20°F), and Hyper Heat / Cold Climate (cooling and heating at all temperatures). Hyper Heat models are recommended for Colorado.

Question 31

What is a SEER rating?

Accepted Answer

SEER stands for Seasonal Energy Efficiency Ratio. It measures how efficiently an air conditioner or heat pump cools your home over an entire cooling season. A higher SEER rating means lower electricity costs. The federal minimum is 14 SEER (or 13.4 SEER2 under the new standard). Most modern systems range from 14-26 SEER.

Question 32

What is a good SEER rating?

Accepted Answer

For Denver's climate, 16-18 SEER is a good balance of efficiency and cost. Systems rated 18+ SEER are premium efficiency and can qualify for utility rebates. Above 20 SEER is high-performance, typically found in variable-speed or inverter systems. The 'best' rating depends on your budget and how long you plan to stay in your home.

Question 33

What's the difference between SEER and SEER2?

Accepted Answer

SEER2 is the updated testing standard introduced in 2023. It uses more realistic conditions (higher static pressure) that better reflect real-world performance. SEER2 numbers are typically 4-5% lower than SEER numbers for the same equipment. For example, a 16 SEER system is approximately 15.2 SEER2.

Question 34

What SEER rating do I need for tax credits?

Accepted Answer

The Colorado state heat pump tax credit ($1,000) requires cold-climate rated equipment. The federal 25C tax credit expired December 31, 2025, but utility rebates through Xcel Energy have increased significantly. Cold climate heat pumps (18+ SEER) qualify for the highest Xcel rebates at $2,250 per heating ton.

Question 35

How much electricity does a heat pump use?

Accepted Answer

Heat pump electricity usage varies by model and climate, but a typical cold-climate heat pump in Denver uses 3,000-6,000 kWh per year for heating and cooling combined. That's roughly $300-$600/year at Xcel Energy rates. Heat pumps use 2-3x less energy than electric resistance heating because they move heat rather than generating it.

Question 36

Is a heat pump gas or electric?

Accepted Answer

Heat pumps are electric. They use electricity to move heat between your home and the outdoors. In a dual fuel setup, the heat pump is paired with a gas furnace for operating cost flexibility - you can switch to gas when rates make it cheaper. All-electric setups pair the heat pump with an electric air handler instead.

Question 37

What size heat pump do I need?

Accepted Answer

Heat pump sizing depends on your home's square footage, insulation, window area, and Denver's climate zone. Oversized systems short-cycle and waste energy; undersized systems can't keep up in extreme cold. A Manual J load calculation is the proper way to determine sizing. Our technicians perform this as part of every estimate.

Question 38

What rebates are available for heat pumps in Denver?

Accepted Answer

Denver homeowners can save $7,750 to $19,300+ by stacking rebates: Xcel Energy (up to $11,250 for cold climate heat pumps), Colorado state tax credit ($1,000), and HEAR (up to $8,000 if income-qualified at 80-150% AMI). Total savings depend on system size and household income.

Question 39

What is the Xcel Energy rebate?

Accepted Answer

Xcel Energy offers up to $11,250 in rebates for heat pump installations. Rebate amounts vary by equipment type and efficiency.

Question 40

What is the HEAR program?

Accepted Answer

HEAR (Home Efficiency and Appliance Rebates) is a federal IRA-funded program offering up to $14,000 for energy upgrades. For heat pumps specifically, you can get up to $8,000. It's income-qualified (80-150% Area Median Income) and provides point-of-sale discounts -you get the savings immediately rather than waiting for a rebate check.

Question 41

Can I stack multiple rebates?

Accepted Answer

Yes. Colorado has some of the best stacking opportunities in the country. Three active layers: Xcel Energy rebates ($2,250/ton), Colorado state tax credit ($1,000), and HEAR (up to $8,000, income-qualified). All three are applied as upfront invoice discounts by your contractor. Each has separate eligibility rules. Total savings: $7,750 to $19,300+ depending on system size and household income. We calculate your exact rebate stack during the free estimate.

Accepted Answer

Yes. We assist with the rebate application process for Xcel Energy and other utility programs. We ensure your equipment meets eligibility requirements and help prepare the documentation needed for submission.

Question 43

What federal tax credits are available for HVAC upgrades?

Accepted Answer

The federal 25C Energy Efficient Home Improvement Credit expired December 31, 2025. While it was active, it offered up to $2,000 for heat pumps and $600 for furnaces/AC. Colorado homeowners can still access the Colorado state heat pump tax credit ($1,000) and substantial utility rebates through Xcel Energy and the HEAR program.

Question 44

How much does furnace installation cost in Denver?

Accepted Answer

Denver furnace installation typically costs $5,310-$7,520 for a standard gas furnace, with the full range being $4,200-$9,800 depending on efficiency and features. High-efficiency 95%+ AFUE models cost more upfront but reduce heating bills by 15-20%.

Question 45

How much does AC installation cost in Denver?

Accepted Answer

Central AC installation in Denver costs $7,450-$9,122 on average for a 3-ton, 16 SEER2 system. The full range is $5,400-$11,200 depending on system size and efficiency. Note: standard AC units don't qualify for utility rebates. Consider a heat pump for rebate eligibility.

Question 46

How much does a heat pump cost in Denver?

Accepted Answer

Heat pump installation in Denver costs $9,100-$28,200 before rebates, with most customers paying $9,400-$14,200 out of pocket after Xcel and HEAR rebates. The median out-of-pocket cost for a cold climate heat pump is $12,200. Income-qualified homeowners may pay significantly less.

Question 47

How much does a mini-split cost in Denver?

Accepted Answer

Mini-split installation in Denver costs $3,200-$5,800 for a single zone and $8,400-$14,500 for multi-zone (2-4 indoor units). Cold climate models qualify for Xcel rebates up to $6,750+. Total system cost ranges from $5,600-$28,500 depending on the number of zones.

Question 48

What affects the price of an HVAC installation?

Accepted Answer

Key factors include: system type and brand, efficiency rating (SEER/AFUE), system size (tonnage/BTU), ductwork condition or modifications needed, electrical upgrades if switching to a heat pump, and accessibility of the installation location. We provide detailed quotes during free in-home estimates.

Question 49

What financing options are available?

Accepted Answer

We offer financing through RENU (Colorado Clean Energy Fund), Wells Fargo Home Projects, and Synchrony. Options range from low-interest loans to same-as-cash promotional periods. Subject to approved credit. Financing can be combined with rebates to minimize out-of-pocket costs.

What's included in the installation price?

Accepted Answer

Our installation prices include the equipment, all materials, labor, old equipment removal and disposal, permits, system testing, and a walkthrough of your new system. We also include assistance with rebate paperwork for qualifying systems. There are no hidden fees.

Question 51

How often should I schedule HVAC maintenance?

Accepted Answer

We recommend annual maintenance for each system: furnace tune-up in early fall (September-October) before heating season, and AC tune-up in spring (April-May) before cooling season. Regular maintenance extends equipment life, maintains efficiency, and helps prevent costly breakdowns.

Question 52

What does a furnace or AC tune-up include?

Accepted Answer

A standard tune-up includes: inspection of all major components, cleaning of coils, burners, and condensate drains, testing safety controls and gas connections, checking refrigerant levels (AC), measuring airflow and temperature differential, and verifying thermostat calibration.

Question 53

How often should I change my air filter?

Accepted Answer

Standard 1-inch filters should be changed every 1-3 months. Thicker 4-5 inch media filters can last 6-12 months. Homes with pets, allergies, or dusty conditions should change filters more frequently. A dirty filter is the number one cause of furnace short cycling and AC freezing.

Question 54

What are signs my ductwork needs attention?

Accepted Answer

Signs of ductwork issues include uneven temperatures between rooms, excessive dust despite regular filter changes, whistling or rattling sounds from ducts, and higher-than-expected energy bills. Ductwork that is 20+ years old may have developed leaks, disconnections, or insulation degradation.

Question 55

How can I improve my home's indoor air quality?

Accepted Answer

Key steps include: regular filter changes, annual HVAC maintenance, adding an electronic air cleaner or whole-home humidifier, maintaining proper humidity levels (30-50% in Colorado's dry climate), and ensuring adequate ventilation. We offer indoor air quality assessments and solutions.
