8 Signs You Need Furnace Repair

1. Some zones of your home won’t get warm.

Your furnace should warm your entire home. If it doesn’t and some areas in your home remain too cold, reach out to one of our HVAC technicians for furnace maintenance or repair.

2. Your home’s energy bills increase suddenly.

If you don’t seem to be using your furnace more, but your home heating bills are rising much more than they should, it could be that your furnace is losing efficiency and requires repair.

3. Loud sounds come from the furnace.

All home comfort systems make some noise, but if your furnace starts to make weird noises—especially banging—it’s a sign you need it examined by an expert.

4. Your heating system constantly turns off and on.

Called short cycling, a furnace that keeps starting and stopping instead of turning on and completing its cycle most likely demands repair from an experienced HVAC technician like the team members at Giordanos Heating and Air Conditioning.

5. The heating system won’t turn on.

If your furnace won’t start, that’s without a doubt a sign you need HVAC repair. If it turns out you need furnace replacement, our heating specialists in Derby can help you choose a new high-efficiency furnace that’s a good match for your home.

6. Water leaking around your heating and cooling system.

Any type of water leaking from your furnace is a sign there’s something wrong that needs timely HVAC repair. We’ll offer a diagnosis and present your repair options, so you can select which works best for your home and budget.

7. Your heating system smells weird.

Furnaces shouldn’t stink. If there’s a persistent nasty smell coming from your furnace, it’s a sign you require repair. If you think you smell gas or a rotten egg smell, it could be a gas leak and calls for immediate action: evacuate your home right away and call for help once you have gotten to safety.

8. Not enough air is coming from vents in your home.

From problems with your ductwork to something wrong with your furnace’s blower motor or a clogged furnace filter, insufficient or weak airflow from vents can be caused by a number of problems that may need HVAC repair, system maintenance or furnace installation.

Furnace Repair: Frequently Asked Questions

Common signs include rooms that won’t warm up, unusual noises like banging, squealing, or rattling, frequent cycling, odd smells when the heat runs, or higher-than-expected heating costs. If your system struggles to maintain temperature, it’s smart to have a technician inspect it.

If you smell gas or a CO detector alerts, shut the system down, leave the home, and contact emergency services and your HVAC company. For minor symptoms, it’s often okay to use the system cautiously, but continued operation can worsen the damage.
This can happen due to thermostat settings, a dirty air filter, pilot or ignition problems, a dirty flame sensor, or a tripped high-limit switch. A technician can pinpoint the cause and recommend the proper repair.
Many repairs can be completed in a single appointment, but the timeline depends on the issue, system accessibility, and whether components are in stock. After diagnosing the problem, your technician can give you a realistic timeframe.
A furnace may be a better candidate for replacement if it needs frequent repairs, is older and inefficient, or has major component issues. If the problem is isolated and the system has been reliable, repair is often the most practical route. A pro can help you weigh efficiency, reliability, and long-term costs.
