Can I get central air conditioning in my house?

The short answer for most residential properties is yes. If you're uncertain, just give us a call or get in touch to confirm. Central air conditioning cools the whole house through your existing ductwork.

Can you replace my swamp cooler with central air?

Yes. If your home has a furnace, we add a coil on top of it and an outdoor unit, and the new AC uses the furnace's ducts. The swamp cooler's duct is not reused. A heat pump goes in the same way and heats too, if your furnace is compatible; older furnaces may not work correctly with a heat pump, or at all. Homes without a furnace usually get a ductless mini-split.

When should I replace my AC?

Typically, we recommend AC replacement when the air conditioning unit has become older than 10 to 15 years and is not worth putting money into repairs. Like any appliance, most AC units have an expected lifetime of 10 to 20 years, lasting around 10 years on average.

How much does an AC replacement cost?

A central AC replacement costs $7,700 to $11,200. Costs vary by project.

How much do you charge for a replacement quote?

It's a free estimate to provide replacement or installation pricing for air conditioning with UniColorado.

I want to get a high efficiency AC

We install high-efficiency AC systems up to 20+ SEER from Carrier, Mitsubishi, and Bosch. Higher SEER means lower operating costs, though the upfront price is higher. We'll walk you through the efficiency vs. cost trade-off during your free estimate so you can decide what fits your budget.

I want to get a heat pump instead of an AC

Heat pumps provide both heating and cooling in one system. UniColorado is the largest heat pump installer in Colorado. We install air-source, cold-climate, and fully electric systems from Mitsubishi, Bosch, and Carrier. A heat pump costs more upfront than a standalone AC. See our heat pump installation page for pricing and details.

How much does AC installation cost in Denver?

AC installation in Denver costs $7,700 to $11,200. Prices include indoor coil, outdoor condenser, installation, materials, and labor.

How long does AC installation take?

Most installs are finished in one day. Fresh installations (homes that have never had central AC) can take longer because of electrical circuit installation (220V/30-60A) and refrigerant line routing. Multi-story homes or complex ductwork modifications can add time.

What size AC do I need for my Denver home?

For a typical 1,500 sq ft home, you'll need a 2-2.5 ton (24,000-30,000 BTU) AC unit. A 2,000 sq ft home typically needs 2.5-3 tons (30,000-36,000 BTUs). A 2,500 sq ft home needs 3-3.5 tons. Proper sizing depends on insulation, window area, sun exposure, ceiling height, and Denver's altitude (5,280 ft). Oversized units cycle too frequently; undersized units struggle to cool. We perform Manual J load calculations during your free estimate.

When is the best time to install a new AC in Denver?

Late winter or early spring (March-April) is the best time to install a new AC in Denver. You'll avoid the summer rush, often get better scheduling availability, and can complete the install before the hot weather hits.

AC ReplacementWhat It Costs

AC Replacement Costs

AC replacement cost varies based on system type, efficiency, and the square footage of your home. Most central AC systems last 15 to 20 years. Replacement is typical when a unit is beyond repair due to age, parts availability, or R22 refrigerant. Newer systems are quieter, more efficient (higher SEER), and variable-speed options significantly reduce outdoor noise.

I was so pleasantly surprised by how amazing my experience was with UniColorado. Thorough, honest, and personable, this company gets it. They’ve earned my business for as long as I live in Denver, and I’d like to thank them again for their great work servicing our outdoor A/C units.

Mikayla N.

The second time this company has been out to fix something going on with our HVAC. They've really done a great job correcting issues caused by the original home builder and explaining things in detail. I won't call anyone else for our HVAC needs. 10/10 would recommend!

How We Install Central AC

Colorado's dry heat and intense UV put unique stress on AC equipment that coastal installers don't deal with. We size every system with a Manual J load calculation, not a tonnage-per-square-foot shortcut. Carrier, Mitsubishi, and Bosch units matched to your home's actual cooling load, and eligible rebates applied at the time of sale.

How It Works

AC Installation Process

Our installation starts with a property assessment where we evaluate your ductwork condition, electrical panel capacity, and condenser placement options. We then recommend an AC system sized to your home using Manual J load calculations. On installation day, our technicians handle the full scope: mounting the condenser, connecting refrigerant lines, installing or replacing the indoor coil, wiring the 220V circuit, and verifying charge levels. After installation, we walk you through thermostat programming, filter replacement schedules, and warranty documentation. The job site is cleaned before we leave.

What's Included

What does AC installation include?

Every UniColorado AC installation quote includes equipment, materials, labor, taxes and rebate processing. There are no hidden fees. Your quote is your final price. Specifically: the outdoor condenser unit, indoor evaporator coil, refrigerant line set, electrical circuit (if needed) and thermostat wiring. We also handle Xcel Energy rebate paperwork and apply all qualifying rebates as upfront discounts on your invoice. Most installs are finished in one day.

Never Had AC Before?

Adding AC to a Home That's Never Had It

Have a house that has ductwork but has never had central air conditioning before? You're looking for a "fresh" AC installation. Total cost varies based on square footage, electrical panel placement and capacity, copper line routing distance, and furnace location. The total cost to install an AC can vary widely depending on the size of your home and the complexity of the installation. Many homes in Colorado have a gas furnace but no air conditioning; this is very common and central AC can typically be added to your existing system. If your home has no ductwork or forced-air heating system (using a boiler for heating, for example), a ductless mini-split system may be a better fit.

AC Type: Central Air Conditioning System (Coil, Condenser, Lineset, 220v Circuit)
Cost Range: $7,700 to $11,200

We're not locked into one brand. Every recommendation is based on your home's cooling load, ductwork condition, and budget. All installations are backed by our Quality Install Guarantee.
