At 1Call, we have the experienced HVAC team to keep your home comfortable in every season, and to respond fast when something goes wrong.

1Call Home Services is Greater Portland and Southern Maine's trusted HVAC contractor, serving Portland, South Portland, Scarborough, Saco, Biddeford, Westbrook, and surrounding communities.

Heat Pump & Mini-Split Installation in Southern Maine

Heat pumps have become one of the most popular heating and cooling solutions for Maine homeowners and for good reason. Modern cold-climate heat pumps handle temperatures well below zero, provide highly efficient heating and cooling from a single system, and can significantly reduce energy costs compared to traditional heating systems.

1Call installs heat pumps and mini-split systems throughout Greater Portland and Southern Maine. We assess your home's layout, recommend the right system for your square footage and usage, and handle the full installation from start to finish. Whether you need a single-zone mini-split for a specific room or a whole-home heat pump system, we have the expertise to get it done right.

Furnace & Boiler Installation and Repair

For many Southern Maine homeowners, a furnace or boiler is the backbone of their home's heating system. When it's working properly, you don't think about it. When it isn't, it's all you can think about.

1Call installs and repairs furnaces and boilers throughout Greater Portland and Southern Maine. Whether your existing system needs a repair to get through the season or has reached the end of its lifespan and needs to be replaced, we assess the situation honestly, give you a clear recommendation, and complete the work correctly. We work with all major furnace and boiler brands and handle both gas and oil systems throughout Southern Maine.

AC Installation & Repair in Southern Maine

Maine summers may be short but they can be brutally humid, and a home without reliable cooling becomes uncomfortable fast. Whether you need central air conditioning installed, an existing system repaired, or a ductless mini-split added to a space that needs cooling, 1Call has the team to handle it.

We install and service central AC systems and ductless cooling solutions throughout Greater Portland and Southern Maine. We assess your home's cooling needs, recommend the right system, and handle everything from installation to seasonal maintenance so your home stays cool when it needs to.

Duct Cleaning, Sealing & HVAC Maintenance

Your HVAC system is only as efficient as the ductwork it relies on. Leaky ducts, dirty filters, and neglected systems waste energy, reduce comfort, and shorten the lifespan of your equipment. Regular maintenance and duct cleaning are the most cost effective ways to keep your HVAC system running at peak performance.

1Call provides duct cleaning, duct sealing, and HVAC maintenance and tune-up services throughout Southern Maine. A properly maintained system heats and cools more efficiently, lasts longer, and is far less likely to fail when you need it most. We recommend seasonal tune-ups before the heating and cooling seasons to catch potential issues before they become expensive repairs.

Emergency & Commercial HVAC Services in Southern Maine

A heating system failure in a Maine winter is a serious situation. Pipes can freeze, temperatures inside a home can drop dangerously fast, and waiting until the next business day is simply not an option. When your HVAC system fails, call 1Call at (207) 220-3232 and we will get a licensed technician to you as quickly as possible.

1Call also provides commercial HVAC services for businesses, offices, retail spaces, and commercial properties throughout Greater Portland and Southern Maine. From new system installations to ongoing maintenance contracts and emergency repairs, we have the licensed team to handle commercial HVAC projects of any size with minimal disruption to your operations.

Your HVAC Questions, Answered

Have questions about heat pumps, furnaces, AC installation, or emergency HVAC repair? We've got you covered. Serving homeowners and businesses across Portland, South Portland, Scarborough, Saco, Biddeford, Westbrook, and Greater Southern Maine.

Are heat pumps effective in Maine winters?

Yes. Modern cold-climate heat pumps are designed to operate efficiently in temperatures well below zero and are an excellent heating and cooling solution for Maine homes. They provide whole-home comfort from a single system, reduce energy costs compared to traditional heating, and qualify for significant state and federal rebates. 1Call installs heat pumps throughout Greater Portland and Southern Maine.

How do I know if my furnace needs to be repaired or replaced?

If your furnace is under 15 years old and experiencing isolated issues, a repair is usually the right call. If it's older, requiring frequent repairs, or struggling to heat your home consistently, replacement is often the smarter long-term investment. 1Call will assess your system honestly and give you a clear recommendation based on what's best for your home and budget.

Do you handle emergency HVAC repair in Southern Maine?

Yes. A heating failure in a Maine winter cannot wait. Call 1Call at (207) 220-3232 and we will get a licensed HVAC technician to you as quickly as possible. We serve Portland, South Portland, Scarborough, Saco, Biddeford, Westbrook, and surrounding communities.

How often should I have my HVAC system serviced in Maine?

We recommend a tune-up twice a year, once before the heating season and once before the cooling season. Regular maintenance catches small issues before they become expensive repairs, keeps your system running efficiently, and extends the lifespan of your equipment. Call 1Call to schedule your seasonal HVAC maintenance.

What is a mini-split and is it right for my home?

A mini-split is a ductless heating and cooling system that conditions a specific zone or room without requiring ductwork. They are an excellent solution for additions, finished basements, home offices, or any space that needs independent temperature control. 1Call installs mini-split systems throughout Greater Portland and Southern Maine.
