Coverage
What Furnace Installation & Repair Covers
A furnace that's oversized short‑cycles and wears out early; one that's undersized runs constantly and still can't keep the house warm. We size every furnace install with a real load calculation and install to current code, including venting and gas line checks.
For repairs, we diagnose ignition faults, gas valve issues, blower motor failures and control board problems — the handful of failure modes that account for most no‑heat calls.

Frequently Asked Questions
Yes — financing is available on work from $500, offered with your estimate. There are no origination fees and no prepayment penalties. Financing provided by Wisetack, subject to eligibility and approval.
Furnace installation and replacement starts from $4,700, depending on unit tier, ductwork condition, and venting requirements. We confirm exact pricing with a written quote after an in‑home assessment.
Furnace repair starts from $185. Exact cost depends on the failed part — an igniter is a modest repair, a heat exchanger or control board replacement costs more. We quote it before starting.
Most gas furnaces last 15–20 years with regular maintenance. Past that range, repair costs and efficiency losses usually tip the math toward replacement.
Common causes are a faulty igniter, a dirty flame sensor, a closed gas valve, or a tripped safety switch from a clogged filter restricting airflow. Most of these are same‑visit fixes.
Yes — a cracked heat exchanger can leak carbon monoxide into your home's air supply. If our technician finds this during a repair or tune‑up, we'll shut the unit down and walk you through replacement options immediately.
Every 1–3 months depending on filter type and household factors like pets or dust. A clogged filter is one of the most common causes of furnace short‑cycling and no‑heat calls we see.
