FAQs

How do I know if my aging gas furnace in Townsend needs professional repair?

Warning signs include uneven heating, frequent cycling on and off, unusual noises (rumbling, squealing, or banging), a sudden rise in gas or electric bills, a yellow or flickering burner flame, and a persistent smell of gas or exhaust. If your thermostat settings no longer match the actual room temperature or you notice cold spots around the house, schedule a service visit right away to prevent potential safety hazards and larger repair costs.

Is it better to repair or replace an older gas furnace that is over 15 years old?

A repair often makes sense if the needed part is minor and your unit has been well-maintained. However, if the heat exchanger is cracked, repair costs exceed 30–40 % of a new-unit price, or your furnace is more than 15–20 years old and suffers repeated breakdowns, replacement is usually more economical. A new ENERGY STAR® furnace can cut heating costs by up to 20 % and comes with a manufacturer warranty, providing long-term savings and peace of mind.

How long does a typical gas furnace repair take in Townsend, and can it be done in one visit?

Most common repairs—such as replacing igniters, flame sensors, blower motors, or gas valves—can be completed in 60–120 minutes during a single visit because our technicians stock the most frequently needed parts on their trucks. Complex issues like heat-exchanger replacement or extensive wiring repairs may require 4–6 hours or a follow-up visit if special-order parts are needed. We’ll always give you a written time estimate before work begins.

What are the most common heat repair issues you see in older gas furnaces?

In Townsend’s damp coastal climate, corrosion and rust are prevalent, especially on burners and heat exchangers. We also routinely deal with worn blower belts or bearings, dirty flame sensors that prevent ignition, cracked igniters, and failing limit or rollout switches. Clogged air filters and blocked condensate drains (for high-efficiency models) can cause short-cycling or shutdowns. Regular maintenance helps catch these problems early and keep your furnace running safely.

Will repairing my old gas furnace improve its energy efficiency and lower my utility bills?

Yes—fixing faulty components can restore lost efficiency. Replacing a malfunctioning igniter ensures proper combustion, cleaning burners eliminates soot buildup, and tuning the gas valve delivers the correct fuel-to-air ratio. Combining repairs with a full maintenance check (filter change, blower cleaning, and duct inspection) can recover up to 5-10 % of lost efficiency. While a new furnace delivers the greatest savings, properly executed repairs prevent excessive energy waste in the meantime.

Do you offer emergency heat repair services in Townsend, and what should I do if my furnace stops working after hours?

We provide 24/7 emergency furnace repair throughout Townsend and the surrounding area. If your unit shuts down at night or on a holiday, turn off the system at the thermostat, check that the gas supply is on, and inspect the breaker panel for a tripped circuit. If you smell gas, evacuate the house and call 911, then contact us once you’re safe. Otherwise, call our emergency line and a certified technician will arrive as quickly as possible—usually within two hours—to diagnose and restore your heat.
