Frequently asked HVAC questions.

It depends on the equipment and how it's been maintained:

Central AC & heat pumps: 12–18 years on average. Coastal Connecticut homes near the sound see corrosion that can shorten that life — coil coatings and proper rinsing make a real difference.

Furnaces: 15–25 years. High-efficiency condensing furnaces tend to land on the lower end of that range; older 80% units often outlast them.

Boilers: 20–30+ years if maintained. Cast-iron boilers in particular can last decades.

Most premature failures we see come down to two things: incorrect sizing at install, and skipped maintenance.

Our rule of thumb: if the repair quote is more than 30–40% of a new system and the equipment is over 10 years old, replacement usually wins on a 5–7 year horizon. Older systems also use phased-out refrigerants that are getting expensive fast.

That said — we don't push replacement when a repair makes sense. If you have a 6-year-old system and a $400 capacitor failure, you fix the capacitor.

Twice a year. Once in spring before cooling season — checking refrigerant charge, condenser coils, electrical components, and condensate drainage. Once in fall before heating season — checking combustion, heat exchanger, ignition, gas pressure, and safety controls.

Most manufacturers also require documented annual service to keep parts and labor warranties valid.

Through a Manual J load calculation. It accounts for square footage, insulation values, window types and orientation, infiltration, and ductwork condition.

What it is not: "your old system was 4 tons so we'll put in a 4 ton." That's how rooms end up with bad humidity, short cycling, and equipment that wears out years early.

Bigger isn't better. A correctly sized system actually runs longer at lower stages, removes more humidity, and lasts longer.

R-410A is being phased out under the AIM Act. New residential and light commercial equipment is shipping with lower-GWP refrigerants — most commonly R-454B (Daikin, Trane, Carrier) and R-32 (Mitsubishi, LG, others).

The practical impact: new equipment is slightly more expensive, but more efficient and serviceable for the long term. Older R-410A systems can still be repaired, but R-410A refrigerant prices are climbing year over year.

Yes — modern cold-climate heat pumps work down to -5°F and below without supplemental heat. Brands like Mitsubishi Hyper-Heat and modern variable-capacity units from Daikin, Carrier, and Trane have closed the gap dramatically over the last decade.

For most Connecticut homes, a properly sized cold-climate heat pump handles 95%+ of the heating load on its own. We typically pair them with the existing furnace or a small electric backup for the few coldest days a year.

Our standard residential diagnostic visit includes the trip, full system check, and written diagnosis with options. Repair pricing is flat-rate and presented to you before any work starts — no hourly meter running.

Commercial service is contracted by account or quoted per scope. PM contract customers get priority response and discounted rates. Call us for current pricing.

Yes — we partner with established home-improvement financing providers that offer 0% promotional terms on qualified purchases, plus longer-term low-APR options for larger projects. We'll walk you through what's available with your proposal.

Yes. Our technicians are factory-trained on most major brands — Carrier, Trane, Lennox, Bryant, Mitsubishi, Daikin, LG, Goodman, American Standard, Rheem, and others. We'll service whatever you have.

Connecticut homeowners can stack several incentives on qualifying high-efficiency equipment: federal Inflation Reduction Act tax credits (up to $2,000 for heat pumps), Energize Connecticut rebates through Eversource and UI, and equipment-specific manufacturer rebates.

We handle the paperwork on every install so you actually get the money. The available programs change yearly — we'll tell you what currently applies to your project.

A straightforward residential AC or heat pump replacement is typically 1 day. A full system swap with new ductwork can run 2–4 days. Mini-split installs are usually 1–2 days per zone.

Commercial RTU replacements depend on crane scheduling and rooftop access — usually 1–2 days per unit, often staged over a weekend or after-hours to avoid tenant disruption.

Yes — fully licensed in Connecticut and insured for both general liability and workers' comp. Certificates of insurance are available on request for property managers, GCs, and homeowner associations.
