Professional New AC Installation in Boulder, CO

Putting central air into a Boulder home is not a box swap — it's a sizing and ductwork decision you live with for 15 years. Get the size wrong and the system runs flat-out on the hottest afternoons and still can't cool the house, because the old sea-level "500 square feet per ton" rule quietly undersizes homes at 5,430 feet. Boulder HVAC Pros runs a Manual J load calculation for your actual home, evaluates your ductwork honestly, and shows you the real numbers on central AC versus a heat pump.

Why We Are The Top AC Installation Company In Boulder

We Size for 5,430 Feet

Correct sizing is the whole job. We run a Manual J load calculation for your home instead of the sea-level rules of thumb that leave Boulder homes undersized for today’s hotter summers.

Neutral Recommendation

Certified across Trane, Carrier, Lennox, Daikin, Mitsubishi Electric, and more, we match the system to your home and show you the honest numbers on central AC versus a heat pump — no one-size pitch.

We Handle the Rebates

Where a heat pump fits, we build the proposal around stacking Xcel Energy and Colorado incentives and file the paperwork most installers won’t touch.

Local Since 2005

A City of Boulder licensed, insured contractor serving the area since 2005, with a written estimate before any work and a workmanship guarantee behind it.

Professional AC Installation You Can Trust

Swamp coolers are hitting their limit. As Boulder’s 90-degree days climb, evaporative coolers increasingly can’t keep up, and more homeowners are moving to refrigerated cooling. Planning the upgrade before the first heat wave lets you compare options calmly.

Rebates reward planning. If a heat pump fits your home, Xcel Energy and Colorado incentives can offset thousands — but capturing them takes equipment selection and a permitted install, not a scramble during a breakdown.

Beat smoke season. Getting cooling in before July means you can keep the house sealed and filtered when Boulder’s air turns, instead of waiting on an install with the windows shut.

Why It Matters

A Bad AC Install Costs You Every Summer

Boulder homeowners often focus entirely on the price tag of a new air conditioning system and overlook the installation itself. That is the most expensive mistake in HVAC. A properly installed mid-range unit will outperform and outlast a premium system installed poorly, and improper installation voids most manufacturer warranties from day one.

What a Poor Install Costs

An undersized or poorly charged AC runs flat-out, wastes energy, and wears out early — the opposite of what you paid for.

Proper Sizing Prevents Short-Cycling

A Manual J sizing for altitude keeps the system from short-cycling on hot afternoons and cooling unevenly.

Proper Refrigerant Charging

Correct charge for 5,430 feet is what lets the system actually cool; a sea-level charge underperforms.

Ductwork Affects Cooling

Even a perfect AC underperforms on undersized or leaky ducts, so we evaluate airflow as part of the job.

Code Compliance Matters

A permitted, code-compliant install protects your warranty and clears a future home-sale inspection.

Installation Protects Warranty

Manufacturer warranties require correct, documented installation; a cut-corner job can void coverage.

The Swamp-Cooler Conversion Other Installers Rush

A large share of Boulder homes ran an evaporative “swamp” cooler for years, then had refrigerated AC added later — sometimes tied into ductwork that was never designed for the airflow central AC needs. The result is a system that looks right on paper but never cooled well, because the duct capacity or return air couldn’t support it. When we convert or replace one of these, we actually evaluate the ductwork — sizing, returns, and leakage — instead of just dropping in a condenser. For a home that never cooled evenly, that’s usually the difference between fixing the problem and repeating it.

AC Installation Across Boulder and the Surrounding Front Range

Installing AC in Boulder is really a choice between two good options. A straight central AC is the honest right call for many homes — if you’ve recently replaced your furnace, you’re comfortable on gas heat, and you want the lower upfront cost. A cold-climate heat pump fits others: it cools and heats from one system and qualifies for rebates a cooling-only AC can’t. We model both and let you decide from the numbers.

Boulder HVAC Pros installs cooling systems across Boulder, Lafayette, Louisville, Superior, Erie, Broomfield, Longmont, Niwot, Gunbarrel, Nederland, and Lyons. Serving the Front Range since 2005, we size for altitude and pull the permits.

Frequently Asked Questions About AC Installation in Boulder

Have questions about AC repair? Below are some of the most common questions we receive from Boulder Area homeowners regarding their AC systems.

How much does AC installation cost in Boulder, CO?

A properly sized central AC runs several thousand dollars; a cold-climate heat pump runs higher before incentives, and duct upgrades add cost. Xcel Energy and Colorado rebates can offset much of a qualifying heat pump. We give a written, itemized estimate showing net cost.

What size AC do I need at Boulder’s altitude?

The right answer comes from a Manual J load calculation that accounts for your home and the 5,430-foot elevation. The old "500 square feet per ton" rule frequently undersizes homes here, which is why so many struggle on hot days.

Should I install central AC or a heat pump?

It depends on your home. A straight central AC is often right if you’ve recently replaced your furnace, are comfortable on gas, and want lower upfront cost; a cold-climate heat pump fits if you also want heating or the largest rebates. Xcel Energy’s top rebate applies to cold-climate units that maintain at least 70% of rated capacity at 5°F with a COP of at least 1.75, so not every unit qualifies — we model both and identify which equipment qualifies.

Can you convert my swamp cooler to central AC?

Yes, and it’s one of the most common installs we do in Boulder. The key is evaluating your ductwork first — many evaporative-to-AC conversions were tied into ducts that couldn’t support the airflow, which is why some never cooled well. We assess duct sizing, returns, and leakage as part of the job.

Do I need a permit to install AC in Boulder?

Yes — a permit and a passed inspection. Skipping it can void your manufacturer warranty and create problems at resale. As a City of Boulder licensed contractor, we pull the permit and handle the inspection.

How long does an AC installation take?

A straightforward central AC changeout is often a day; a ductless system or a heat-pump conversion can take longer, and duct upgrades add time. We give you a clear timeline in the written quote.
