Northern Colorado summers swing from mild mornings to triple-digit afternoons, and the day your air conditioner quits is never a convenient one. A Plus Heating & A/C keeps homes cool across Berthoud and the surrounding communities with fast, dependable AC service seven days a week.Â
We install, repair, and maintain every kind of system, including central, ductless mini-splits, heat pumps, and window units. If you’re looking to upgrade, we are a certified partner for both Lennox and Carrier, and we’ll match your home with the right system that’s built to last.

We install central air conditioners, ductless mini-splits, and window units sized correctly for your space. As a certified Lennox and Carrier partner, we set up high-efficiency systems to manufacturer spec so they run quietly, reliably, and affordably for years.

Weak airflow, warm air, strange noises, or a unit that won't start? We find the real cause instead of guessing. From refrigerant and capacitor problems to failed compressors, we repair central, ductless, and window systems and explain the fix before we begin.

A spring tune-up keeps your AC efficient through the hottest months and catches small problems before they sideline you. We clean coils, check refrigerant, test controls, and replace filters, and members get two visits a year plus priority scheduling.

Ask us about current Lennox and Carrier manufacturer rebates and Xcel Energy utility incentives on qualifying high-efficiency systems. A Plus adds free estimates, special discounts for seniors and military members, and membership credits you can put toward your next upgrade.

Hundreds of Northern Colorado homeowners have trusted our local, family-owned company to keep them cool, with a 5-star service reputation since 2014.
If your home already has ductwork, central air cools the whole house evenly and efficiently. Ductless mini-splits are ideal for additions, older homes without ducts, or zoning specific rooms. Window units are a low-cost fix for a single room. We'll help you weigh comfort, efficiency, and budget.
Bigger isn't better — an oversized unit short-cycles, wastes energy, and leaves humidity behind. We calculate the right capacity based on your home's square footage, insulation, windows, and layout, so your system runs efficiently and lasts.
A standard central AC or mini-split swap usually takes most of a day. Adding ductwork or converting to ductless takes longer. We'll give you a clear timeline with your estimate so you can plan around it.
Common culprits are low refrigerant, a dirty coil, a failing capacitor or compressor, or a clogged filter choking airflow. We diagnose the actual cause rather than just topping off refrigerant, then explain the repair and cost before we start.
If your unit is under about 10 years old and the repair is minor, fixing it usually makes sense. Past 12–15 years, or when a major part like the compressor fails, a new high-efficiency system often costs less over time. We'll give you an honest recommendation either way.
We're open seven days a week and move quickly on no-cooling calls, especially during heat waves. Members get priority scheduling. Call us today, let us know your needs, and we'll get you on the books.
Once a year, ideally in spring, before the cooling season. An annual tune-up keeps efficiency high, helps protect your manufacturer warranty, and catches worn parts before they fail on the hottest day of the year.
Don't sweat through another Colorado summer with an AC you can't count on. From quick repairs and spring tune-ups to brand-new Lennox and Carrier installations, A Plus is ready seven days a week with honest estimates and five-star service.
