Furnace Repair & Heating Services
A broken furnace isn't a tomorrow problem. Urgent HVAC Service connects homeowners with certified furnace repair technicians nationwide — same-day service available in most areas, 24/7 emergency response when the heat goes out.
Common Furnace Problems
Furnaces often signal trouble before they fail completely. Recognizing these symptoms early prevents overnight emergencies and costly breakdowns during the coldest nights of the year.
When the furnace runs but produces no warm air, technicians check the ignitor, gas valve, flame sensor, and heat exchanger. Each component requires a different diagnostic approach — guessing wastes time and money.
Modern furnaces use hot surface ignitors or electronic spark systems. A cracked ignitor, faulty control board, or gas supply issue can prevent the burner from lighting. Technicians test each component in sequence to pinpoint the failure.
Banging on startup often indicates delayed ignition from a dirty burner. Rattling points to loose components or ductwork. Squealing typically means a worn blower belt or bearing. None of these sounds should be ignored.
A furnace that turns on and off repeatedly without reaching setpoint is usually tripping a limit switch due to overheating — most commonly caused by a dirty filter, blocked return air, or a failing blower motor.
Efficiency losses from a cracked heat exchanger, dirty burners, failing inducer motor, or worn blower assembly force the furnace to run longer and harder. Tune-ups frequently restore efficiency and cut monthly costs.
A cracked heat exchanger is the most dangerous furnace failure — it allows combustion gases into living areas. If your CO detector activates or you smell exhaust indoors, shut the system off and call immediately.
Service Coverage
From emergency no-heat calls to annual tune-ups, here's what certified furnace technicians in our network handle — and what you can safely check before calling.
Call immediately — and consider leaving the home — if you smell gas, hear hissing near the furnace, or if your CO detector activates. These are life-safety situations. Turn the system off at the main shutoff, open windows, and call from outside.
How It Works
Urgent HVAC Service matches homeowners with qualified furnace repair professionals in their area — fast, with no runaround.
Tell us what you're experiencing — no heat, won't ignite, short cycling, strange noises, CO concern, or just need a tune-up before winter.

Questions Answered
What to expect from furnace repair, how to evaluate costs, and when to call vs. replace.
Furnace repair costs range widely. Ignitor replacement typically runs $150–$300. Flame sensor service is usually $80–$200. Blower motor replacement can run $400–$900 depending on the motor type. Control board replacement is often $500–$1,000+. Emergency or after-hours service typically carries an additional fee. Always get a written estimate after diagnosis before authorizing repairs.
If your furnace is under 15 years old and the repair is less than 30–40% of replacement cost, repair is usually the right call. Over 15–20 years old with recurring repairs, or if the heat exchanger is cracked (a safety issue requiring immediate action), replacement typically makes more financial and safety sense. A technician can walk you through the math based on your system's specific condition.
A standard furnace tune-up typically includes: burner cleaning, heat exchanger visual inspection, flame sensor cleaning, flue and venting check, filter replacement or inspection, blower cleaning, safety control testing (limit switch, pressure switches), gas pressure verification, and a combustion analysis on higher-end tune-up packages. Annual tune-ups are the single best way to prevent mid-winter breakdowns.
Short cycling — shutting off before reaching the thermostat setpoint — is most commonly caused by a clogged air filter causing the heat exchanger to overheat and trip the limit switch. Other causes include a failing flame sensor (shuts off gas after ignition), blocked flue, or a faulty control board. Replace the filter first; if that doesn't resolve it, call a technician.
No — do not operate the furnace if you smell gas. Turn off the furnace at the thermostat, turn off the gas shutoff valve (handle perpendicular to the pipe), open windows, avoid using light switches or electrical devices, leave the home, and call your gas utility from outside. A certified technician should inspect the system before you restart it.
