Why Heating Repair Costs Vary So Much
Heating repair costs vary because they can range from simple issues to complex repairs and major component replacements.
No trustworthy heating contractor can give you an upfront quote without looking at your system. Estimates are usually in a ballpark range, but it always takes an on-site diagnostic service to identify the real problem and quote the repair.
Here’s what typical heating repair costs look like for homes in Suffolk County:
- Diagnostic Service Fee ($90 – $150) – Depends on the complexity of your system and may be waived when booking a repair.
- Minor Repair ($150 – $450) – Simple issues like replacing an ignitor or sensor.
- Major Repair ($1,000 +) – The most complex repairs may take several hours. Cost is based on labor, materials, and components. Examples include heat exchanger replacements and inducer motor repairs.
Is it Better to Repair or Replace My Furnace? The 50% Rule
It’s better to repair your furnace in most cases. However, it’s not always economical to repair a furnace, so we follow the 50% rule as a guideline.
- We recommend repairs when the unit is less than 10 years old, and the repair cost is less than 30% of a new furnace.
- We recommend a replacement if the repair exceeds 50% of the cost of a new unit, or if the system is over 10 years old and has a history of costly repairs.
Professional HVAC Repair Tip: There are some “fly-by-night” contractors that pop up in Suffolk County during the winter months when furnace repairs are in high demand. These contractors might offer deals that seem too good to be true, like flat-rate repairs. They may provide temporary solutions, but leave you with no options when the repair or workaround fails.
Always insist on a local HVAC contractor with an established presence. Soundview HVAC has served Suffolk County, from the South Shore to the North Fork, since 2000.
What to Do If Your Furnace Isn’t Working
Before you call a contractor, follow these simple tips when your furnace isn’t working:
- Check your thermostat. Make sure it’s set to heat, and the temperature is at least 5°F higher than the room temperature. If the screen is blank, check the thermostat batteries.
- Check the air filter. A clogged filter can cause overheating and frequent shutdowns.
- Ensure your furnace is turned on. There should be a power switch near the unit on a wall or pillar.
- Check your circuit breaker. HVAC equipment is usually labeled as “Furnace” or “HVAC”. If it has tripped to the middle, flip it off for 30 seconds and then turn it back on.
- Check the gas valve. It should be open (running parallel to the pipe).
- Reset the system. Sometimes, a system reboot can restart the ignition cycle. Turn the furnace off at the thermostat or power switch. Wait 30 seconds, and turn it back on.
If these troubleshooting steps don’t work, you will need an expert diagnosis to identify the problem. You will receive a detailed quote including all parts and labor.
