Furnace & Heating Repair Services in Maine

When to Call Heritage For Furnace Repairs 

No Heat Blowing: No hot air may mean you need to change the air filter. If replacing the filter doesn’t fix the problem, you should call a professional to inspect your furnace.

Drastic Temperature Changes: If you suddenly feel cold air when the furnace is running, you should turn off the heat, wait five minutes, and then turn it back on at 4-5 degrees higher than the current set temperature. If this doesn’t work, try changing the thermostat batteries. If you still get sudden bursts of cold air from your furnace, call for repairs.

System Won’t Turn On: When your furnace won’t turn on, that is usually an issue with your pilot light. Your pilot light should be lit all the time, so you should reset the furnace if it ever goes out. If the pilot light doesn’t relight when you reset the furnace, call Heritage for help.

Don’t ignore heating issues, however small. Even if your furnace is working, that doesn’t mean it’s working at its best. Here are some common signs that your furnace is overdue for routine maintenance or needs professional heating repairs.

• Furnace is blowing heat, but it’s not very hot air
• Heating system cycles on and off constantly
• Strange noises coming from the unit when it runs
• Odd smells in the air when blowing heat
• Your pilot light is out if you have a gas furnace

Common warning signs include unusual noises like banging or squealing, uneven heating, frequent cycling, a yellow or flickering pilot light, cold air from vents, rising energy bills, and strange odors when the furnace runs. If you notice any of these, contact Heritage for a professional diagnosis.

Yes. A furnace failure during a Maine winter is urgent. Heritage provides emergency heating repair services so you can restore warmth to your home as quickly as possible. Contact us immediately if your furnace stops working or you suspect a safety issue.

Heritage recommends annual furnace maintenance before each heating season. Regular maintenance catch small problems early, improve efficiency, and reduce the risk of unexpected breakdowns when temperatures drop. A well-maintained furnace also lasts longer and operates more safely.

If your furnace is under 15 years old and the repair cost is modest, a repair is usually the better option. If the unit is older, requires frequent repairs, or has a cracked heat exchanger, replacement is typically more cost-effective. Heritage will give you an honest recommendation based on your system’s condition.
