Frequently Asked Questions

If you have a warranty you probably remember registering the equipment, because most manufacturers require it, and if a system was never registered after installation, the warranty may be void.

Most manufacturers let you check warranty status on their website by entering the unit's serial number, which pulls up the full coverage on that system. If you cannot find it, we are happy to look it up for you.

Banging, clanging or rattling from your indoor unit usually means something came loose internally, and the louder the rattle, the worse the underlying problem. Different sounds point to different failures, which helps us narrow the diagnosis before we even arrive:

• Hissing: refrigerant leak or duct leak
• Clicking: relay, control board or ignition issue
• Humming or buzzing: electrical, capacitor or contactor
• Screeching: blower or fan motor bearings
• Grinding: motor failure in progress; shut it off
• Rattling: loose panel, debris or a failing component
• Water dripping: clogged condensate drain

It is not strictly required, but it is always advised. Today's high-efficiency systems earn their energy ratings collectively, so you need a matched set to actually get the efficiency you paid for. Because the two halves usually wear at the same rate, replacing both at once is a bit like replacing a washer and dryer together. It also saves you money: one visit instead of two means less labor overall.

A dirty filter restricts airflow, so warm air backs up in the system. The heat causes the sheet metal in your ductwork and furnace to expand and bow outward. When the heating cycle ends, the metal cools and snaps back. That is the bang or pop you hear. Start with a fresh filter; if it continues, the return ductwork may be undersized.

Maintenance keeps your system operating at its best year after year, which saves money on utility bills. A system on annual maintenance also experiences far fewer malfunctions, lowering the frequency and cost of repairs. Our full-service maintenance checks include:

• Checking the parts and air filters
• Cleaning the heating coil and interior components
• Tuning the thermostat
• Verifying all safety features

You receive a comprehensive report of everything we found once the tune-up is complete. See the full checklist.

The compressor in a high-efficiency air conditioner has a built-in high and low speed. That lets your home cool more evenly, dehumidify considerably better, and start up more gently. These compressors also cycle on and off less often, which conserves energy and reduces wear on the system.

With annual maintenance, expect roughly 15–20 years from a gas furnace, 12–18 from an air conditioner or heat pump, and 20–30 from a well-maintained boiler. Systems that never get serviced routinely fail years earlier. If yours is in the back half of that range and facing a major repair, we will show you the repair-versus-replace math honestly before you decide.

Yes. We offer financing on approved credit for new installations, so a replacement does not have to wait for the perfect moment. Ask us about current options when we provide your free in-home estimate.

In-home estimates on new installations and replacements are free. Diagnostic service calls on an existing system carry a service charge, which we will tell you about clearly when you book, never as a surprise on the invoice.

We serve Hunterdon, Somerset and Warren County, New Jersey and the surrounding areas, 34 towns including Clinton, Flemington, Bridgewater, Somerville, Washington, Hackettstown and Basking Ridge. See the full list of towns, and call us if yours is not on it.

Leave the building immediately, do not operate light switches, appliances or phones inside, and call your gas utility's emergency line or 911 from a safe distance. Do not go back in until they clear it. Once the utility has made the situation safe, call us and we will inspect and repair the equipment side.
