From historic properties near Higgins Beach to modern builds off Route 114, Gelinas HVAC Services has serviced every heating and cooling configuration across Scarborough since 1994, including steam boilers, oil furnaces, cold-climate heat pumps, and complex ductwork.

Do you repair both heating and cooling systems in Scarborough? Yes, our licensed HVAC technicians repair furnaces, boilers, steam boilers, heat pumps, central AC, ductless mini-splits, ductwork, zone controls, and thermostats.

How do 24/7 emergency HVAC repairs work in winter? Heating failures during a Maine winter are prioritized immediately rather than booked as standard appointments to protect your home and plumbing.

Will I receive an upfront estimate before repair work begins? Always. You receive a firm, transparent quote and approve the price before any repair work starts.

Do you repair oil heating systems in Scarborough homes? Yes, Gelinas holds official Maine oil and fuel licenses. Oil furnaces and boilers are common in Scarborough, and our technicians service them daily.

Which HVAC equipment brands do you service? We work on all major equipment brands and serve as a certified dealer for Fujitsu, Bosch, Weil-McLain, Bradford White, and Viessmann.

Addressing heating and cooling issues promptly prevents minor component faults from turning into costly emergency repairs. If your system requires frequent service calls, enrolling in twice-yearly HVAC maintenance is usually far more economical than paying for repeated breakdowns. Our dedicated service pages cover specific equipment repairs, including furnace repair, boiler and heating repair, heat pump repair, AC repair, mini split repair, and thermostat repair. When aging equipment can no longer deliver reliable comfort, planning a full HVAC installation is the safest path forward.

If your heating and cooling system is showing any of these warning signs, booking a repair call before the next big temperature shift is the right call:

  • Rooms hold noticeably different temperatures even when your thermostat is set correctly.
  • Airflow at the registers has dropped off compared to last season.
  • The system cycles more often than it used to, or runs endlessly without reaching setpoint.
  • You hear loud metallic banging in the ductwork whenever the blower engages.
  • Energy bills have climbed steadily without any change in your daily routine.
Safety issues require a different level of urgency. If you notice a yellow or flickering burner flame, visible soot, or a carbon monoxide alarm on any gas or oil appliance, leave the house and call 911 immediately. Once the property is clear and safe, call (207) 672-2801 to book your free estimate.

Since 1994, homeowners across Scarborough and Greater Portland have trusted Gelinas HVAC Services for honest diagnostics and reliable HVAC repair. As a local, family-owned business, we take pride in fixing issues correctly the first time with fully licensed and insured technicians. Reach out to our team at (207) 672-2801 or book online to speak with a live representative.

HVAC Problems We Solve Most Often

Keeping a home comfortable in Southern Maine requires equipment that can handle damp summers and freezing winters alike. When our trucks arrive at Scarborough homes for an emergency repair, we consistently run into a handful of recurring system faults. Here are the issues we encounter most frequently in the field and how we restore balanced comfort.

Weak airflow from supply vents usually points to a clogged air filter, dirty ductwork, or a failing blower motor assembly. When air cannot move freely across the heat exchanger or cooling coil, the system overheats or freezes and triggers safety cut-off switches. We thoroughly clean the blower assembly, check static pressure levels, inspect duct runs, and adjust motor speed taps to re-establish optimal airflow throughout the house.

A heating system that fires up briefly and immediately shuts down is usually suffering from a dirty or oxidized flame sensor rod. Carbon buildup prevents the control board from sensing the flame, forcing the system into a protective lockout mode. We pull the sensor rod, clean off microscopic oxidation with specialized abrasives, check microamp readings, and test the full ignition sequence for dependable startup.

When your living room feels freezing while upstairs remains sweltering, the issue often stems from faulty wiring or poor thermostat placement. Broken control wires or internal sensor drift cause the system to short-cycle or run endlessly. We test signal voltages, repair corroded wiring, recalibrate sensor offsets, and reposition control units away from drafty doorways or direct sunlight.
