Heating Services FAQs

East Coast HVAC provides complete heating services for homeowners and light commercial properties in New Hampshire and Southern Maine.

If your furnace is over 15 years old, requires frequent repairs, struggles to heat your home evenly, or causes rising energy bills, it may be time to consider replacement.

Yes. East Coast HVAC provides professional boiler repair services for homeowners in Dover, Portsmouth, Rochester, Exeter, and surrounding Seacoast communities. Our technicians diagnose issues quickly and work on many types of gas and oil boiler systems to restore reliable heat as fast as possible.

Routine heating maintenance helps prevent unexpected breakdowns during cold weather while improving energy efficiency and system lifespan. In New Hampshire and Maine, winter heating systems work hard for several months each year, making annual tune-ups especially important. Regular maintenance can also help identify small issues before they become expensive repairs.

Some of the most common warning signs include uneven heating, strange noises, rising utility bills, weak airflow, frequent cycling, unusual smells, or a furnace or boiler that will not stay running consistently. If you notice any of these issues, scheduling heating service early can help avoid a complete system failure.

Absolutely. East Coast HVAC helps homeowners improve comfort and reduce heating costs with high-efficiency furnaces, boilers, heat pumps, smart thermostats, and preventative maintenance services.

They did difficult work with a great attitude.  They were creative problem solvers as our equipment was in a tight attic space. They always worked in an orderly way and cleaned up completely. Thank you Bryan and Heath.

 Trustindex verifies that the original source of the review is Google. We are very pleased with the installation of a minisplit ac system by east coast heating & air. The entire process from start to finish was very easy. The consultant & install team were polite, promp, knowledgeable, neat, organized, patient answering any questions & hard-working. It is obvious that they were well trained & worked as a team.  The pricing was very fair.
Earlier we had installed a furnace after the flood at the  beach also by East coast heating and cooling . They came to our rescue immediately 2days before new years so that we were warm & comfortable for the winter. Again that team was was equally all of the above-mentioned. Thankyou so much for the caring attitude toward your customer.  Highly recommend this company.  Maryann & Jack.
