Do you offer free estimates?

Yes — we provide free estimates for all new installations, heat pump projects, and major system replacements. Diagnostic service calls for existing systems are quoted upfront before any work begins.

Do heat pumps actually work in Maine winters?

Absolutely. Modern cold-climate heat pumps like the ones we install operate efficiently down to -13°F. Many of our customers use them as their primary heat source year-round, even in Gorham and Freeport.

How do I qualify for Efficiency Maine rebates?

As an authorized Efficiency Maine contractor, we handle the rebate paperwork for you. Most qualifying heat pump installations receive between $1,500 and $10,000 back. Book a free consultation and we'll walk you through exactly what you're eligible for.

What is your emergency response time?

When you call our emergency line, you reach a technician directly — not a dispatcher or answering service. We aim to be on-site within two hours for heating emergencies during the heating season.

What HVAC brands do you service and install?

We service all major brands including Mitsubishi Electric, Bosch, Samsung, Carrier, Lennox, Trane, Daikin, Fujitsu, Weil-McLain, Burnham, Bradford White, Viessmann, Lochinvar, HTP, Navien, and more.

How often should I have my HVAC system serviced?

We recommend annual maintenance for all heating and cooling systems — ideally in the fall for heating and spring for cooling. Regular tune-ups prevent breakdowns, maintain efficiency, and extend the life of your equipment by years.

Is it ever worth repairing a 20-year-old furnace?

Rarely. A 20-year-old furnace is at the end of its serviceable life. Even if the immediate repair is affordable, you're likely 12–18 months from another failure. At that age, replacement — especially with a heat pump and available rebates — almost always makes more financial sense.

How do I find out if my system qualifies for Efficiency Maine rebates?

The best way is to call us for a free estimate. We're an authorized Efficiency Maine contractor and check rebate eligibility for every customer. Rebates apply to qualifying heat pump systems including mini-splits, central heat pumps, and cold-climate heat pumps.

My AC needs a new compressor — is it worth fixing?

Compressor replacements are expensive ($1,200–$2,500+) and usually only make sense on systems under 8–10 years old that are otherwise in good condition. On an older system, replacement is typically a better investment.

How long should a new HVAC system last in Maine?

A properly sized and installed gas furnace should last 15–20 years. A central AC or heat pump, 12–15 years. A boiler, 20–30 years with annual maintenance. These lifespans assume annual tune-ups and regular filter changes.

Southern Maine Mechanical | HVAC, Heating & Cooling

A failing HVAC system puts you in an uncomfortable position: you're facing a repair bill, you're not sure how much life the unit has left, and you don't want to overpay for a stopgap fix on a system that's going to need replacement anyway. Here's how technicians actually think through this decision — and how Maine homeowners can apply the same logic.

The 50% Rule (A Starting Point)

The most common guideline in the HVAC industry: if a repair costs more than 50% of the installed cost of a new equivalent system, replacement is usually the better choice. This is a rough heuristic, not a hard rule, but it's a useful anchor.

For context in Maine: a mid-range gas furnace replacement runs $4,000–$7,000 installed. A mid-range central AC replacement runs $4,500–$8,000. So a $2,000+ repair on a furnace, or a compressor replacement on an older AC unit, starts to push toward replacement territory.

Age Matters More Than Anything

Equipment age is the most important factor in the repair-vs-replace decision. Here are typical lifespans for Maine homeowners:

Gas furnace: 15–20 years
Central air conditioner: 12–15 years
Heat pump: 12–15 years
Boiler (gas/oil): 20–30 years with maintenance
Mini-split: 15–20 years

A 10-year-old furnace that needs a $400 igniter replacement is an easy call — repair it. A 17-year-old furnace that needs a $900 heat exchanger is a much harder call, because even if the repair is done, the blower motor, control board, and gas valve are all at end-of-life too.

How Efficiency Maine Rebates Change the Math

This is where the calculation shifts dramatically for Maine homeowners compared to other states. If you're replacing a gas furnace or oil boiler with a qualifying heat pump system, you may be eligible for:

Efficiency Maine heat pump rebate: $1,500–$10,000
Federal Inflation Reduction Act tax credit: 30% of installed cost, up to $2,000/year
If income-qualified: additional incentives through MEA and other programs

A $12,000 heat pump installation with $5,000 in combined rebates and credits nets out to $7,000 — while also eliminating your heating fuel cost and providing whole-home cooling. That changes the repair-vs-replace math significantly. A $1,200 repair on a 14-year-old oil furnace looks different when the alternative is a $7,000 net heat pump with no more oil bills.

Repairs Worth Making (Even on Older Equipment)

Not every repair on an older system is a bad investment. These repairs are generally worth making even if the unit is 10–15 years old:

Igniter replacement ($150–$350) — simple part, simple repair
Flame sensor cleaning or replacement ($75–$200) — easy fix, often resolves intermittent shutdowns
Capacitor replacement on AC ($150–$300) — very common, cheap fix
Thermocouple replacement on boiler ($100–$250) — straightforward
Pressure relief valve on boiler ($150–$300) — safety component, worth maintaining

Repairs That Signal It's Time to Replace

Heat exchanger replacement ($800–$2,000+) — if the furnace is over 12 years old, this is often a replacement trigger
Compressor replacement on AC ($1,200–$2,500) — on any unit over 10 years old, replacement is often a better value
Control board replacement ($400–$900) on an older unit
Second major repair within two years on the same system
R-22 refrigerant recharge on an old AC (R-22 is discontinued and extremely expensive)

If you're on the fence, ask your technician to give you a rough age-and-condition assessment of the whole system, not just the failed component. A good tech will tell you honestly if additional failures are likely within 1–2 years.

What We Tell Our Own Customers

There's no universal right answer — it depends on your system's age, overall condition, your fuel costs, and what replacement would actually cost you after rebates. What we try to avoid is recommending an expensive repair on a system we genuinely believe will fail again in 12 months. That's not fair to the customer.

We're happy to walk through the numbers with you — repair cost, system age, replacement cost after rebates, and expected fuel savings. That conversation is free, and we have no interest in pushing you toward replacement if a repair makes more sense.
