Last updated:
Furnace repair begins with the thermostat call, electrical supply, ignition sequence, airflow, controls, and safety-related components appropriate to the installed equipment. Home+ Air explains the findings and presents the repair scope and price before authorized work begins.
Nassau County homes use furnaces with different fuels, venting arrangements, controls, duct systems, and installation histories. Provide the furnace make, model, fuel, error code, noises, odors, and when the problem began so service capability can be confirmed. Call for a current appointment window or emergency ETA; timing depends on technician availability, location, traffic, weather, and demand.
We do, across Nassau County and Western Suffolk. Calls reach a live dispatcher 24/7, including nights and weekends, and dispatch confirms the next open arrival window for your address before you commit to anything.
The residential diagnostic is $199 and it buys you a written cause plus a fixed repair price before any work starts. Most common repairs land between $200 and $700 in parts and labor; you approve the number first, and larger jobs come with a repair-versus-replace comparison.

Gas, electric, and high-efficiency condensing furnaces across covered Nassau County and Western Suffolk ZIP codes — $199 diagnostic, written repair pricing before any work starts.
Yes. Gas furnace repair is the most common heating call we run in Nassau County and Western Suffolk — igniters, flame sensors, pressure switches, inducer motors, blower motors, gas valves, control boards, and cracked or failed heat exchangers. The $199 diagnostic covers the visit and testing, then the repair is quoted at a fixed price you approve first.
Yes. Electric furnaces and electric air handlers show up in Long Island additions, converted garages, and homes without gas service. Typical repairs are heating elements, sequencers, contactors, limit switches, and blower motors. Diagnostics include an amp draw check on each element and a breaker and wiring inspection, because an undersized circuit is a frequent cause of repeat failures.
The diagnostic is $199 and is waived for Home+ Comfort members. Most completed repairs land between $250 and $900 depending on the part — igniters and flame sensors sit at the low end, blower motors, gas valves, and control boards at the high end. Anything approaching heat-exchanger replacement gets a written repair-versus-replace comparison before you decide.
A furnace service visit covers ignition and flame sensing, gas pressure, temperature rise across the heat exchanger, blower amp draw, filter and airflow, safety switches, venting, and thermostat operation. Findings are written down with photos, and anything outside safe operating range is explained with a price before work is authorized.
Repair usually wins when the furnace is under 15 years old and the fix is a single component. Replacement is the better spend when the heat exchanger is compromised, the unit is 18-plus years old, or repairs approach a third of replacement cost. High-efficiency gas furnace replacement is planned here in a $4,800–$9,500 range, and a heat pump conversion may qualify for the PSEG Long Island Home Comfort rebate of $4,000 market rate or $7,500 income-qualified.
