Specialty 01, Natural Gas Heating

Heating

We specialize in natural gas heating. Furnace repairs, annual inspections and full installs, quoted by Chris and backed by a one-year labor warranty and ten years on parts.

Chapter 01

What a Rhode Island gas furnace actually fails on.

A cracked heat exchanger is the one that matters most, because it is a safety issue, not just a comfort one. Combustion gases can leak into the airstream instead of going up the flue, and it is not something you can see from the basement stairs.

Short of that, most calls are a dirty flame sensor that stops the burner from staying lit, a flue or vent that has gotten partly blocked, or short cycling because static pressure in the ductwork has climbed higher than the blower motor can push against. All three show up as a furnace that runs rough, not one that is dead, which is why they get ignored until a cold snap forces the issue.

The annual inspection, step by step.

One visit covers combustion and air-fuel mixture, the flue and vent, the safety devices, the heat exchanger, the air filter, the motor and fan, the duct and piping, and the thermostat.

The combustion check and the heat exchanger check are really one conversation: burning natural gas cleanly depends on the exchanger being intact, so checking the flame and checking the metal are two ways of catching the same failure before it becomes a carbon monoxide problem instead of a repair bill. The flue and vent inspection is the other one worth understanding, since a partly blocked vent is invisible from inside the house and shows up as a furnace that keeps shutting itself off on its own safety switch.

Motor and fan cleaning and the duct and piping inspection round it out, along with a straightforward thermostat function test to confirm the system actually responds to what it is being told to do.

Chapter 03

When a repair stops being the cheaper answer.

Age is part of it, and so is a heat exchanger that is already showing wear rather than failed outright. A furnace that has needed the same fix two winters running is usually telling you something a single repair receipt does not show.

The estimate is free either way, and Chris writes it himself after actually looking at the equipment, so the repair-versus-replace call comes with a real number attached instead of a guess.

After the install, the first winter.

Labor is covered for a year and parts for ten, and if something does go sideways, service is normally out within 24 to 48 hours.

Past that first winter, the same annual inspection that catches problems on an older furnace is worth keeping up on a new one too. It costs less to catch a dirty flame sensor in October than to lose heat on the coldest night of the year.

“My furnace was backfiring and needed a good cleaning. My furnace was inspected and taken apart for cleaning. Once it was all tuned up it was running like new again. Pretty good for a 38-year-old gas furnace! Fair pricing, great service, honest people. Can’t ask for much more.”
