Does Your Furnace Need Repairs? Here’s How To Tell

We sometimes get calls from customers wondering if their heating system needs repairs. Here’s a handy checklist to help you know when it’s time to call us for heating repair.

  • Your heating system won’t turn on at all, even after resetting the unit and checking the circuit breaker. A part failure could be to blame, but we may be able to fix the issue with something quick and easy like thermostat troubleshooting.
  • Your furnace will only blow cool air. There might be something wrong with the blower motor or the heat exchanger. Repairing the heat exchanger can be expensive, so we’ll help you weigh the pros and cons of fixing it vs. replacing the unit.
  • Your furnace turns on but doesn’t run. This may happen if your furnace’s pilot light or electric ignition has stopped working.
  • Your air quality is poor, and you regularly see dust drifting through your home. This could indicate a problem with your air filter or ductwork rather than the furnace itself. Ducts need regular cleaning, and your system needs a new air filter every 30 to 90 days (depending on the filter’s thickness).
  • Your furnace runs constantly even after reaching the temperature you set on the thermostat. This points to a problem with the limit switch, which is responsible for telling the unit when to switch on and off. A constantly running furnace could spark a blaze at any moment, so call us for emergency heater repair right away.
  • Your furnace is making loud, scary noises, such as grinding, thumping, or squealing. If your furnace makes a constant racket, there could be something wrong with the blower belt or bearings. Learn more about furnace noises and what they mean
  • Your furnace smells nasty when you turn it on. If this is the first time you’re turning the furnace on for the season, a slight burning smell is normal, but it should fade after a few minutes. If the burning smell persists, you may need repairs. You should also call us for heating repair right away if you smell gas, which points to a possible carbon monoxide leak.

Should You Repair or Replace Your Heating System?

Your heating system needs repairs, and you’re trying to weigh the cost of those repairs against buying a new unit. Which option is best for your home? Here’s how to make the call:

  • Your furnace has broken down more than once in the past couple of years. This indicates that the system is on its last legs, and you’ll probably face the need for more repairs sooner rather than later. It makes more financial sense to replace the failing unit with a new one.
  • Your heating bills skyrocket when temperatures dip, and they’re way more expensive than normal. Failing furnaces have to work extra hard to heat your home, and that means higher energy bills. Switching to a new unit could save you hundreds in just a few years.
  • Your furnace is 15+ years old. Around this time, problems tend to start cropping up, so it’s better to replace the unit before it fails completely.

Heating Repair FAQs

How much does it cost to repair or replace a heating system?

Customer: “How much is this going to cost me?”

Mullen Tech: “That’s a great question! Repairs usually can range depending on the issues you are facing with your system. If it’s something more serious, like needing a full system replacement, it could lead to larger pricing.”

Customer: “How will I know what is needed, or if I need to even spend money on a new system?”

Mullen Tech: “I get it—it can be a lot to have to deal with. But don’t worry! If you schedule online with us, I’ll take a look, figure out exactly what’s needed, and go over all the costs with you before we do anything. That way, there won’t be any surprises.”

How often should I schedule heating system maintenance?

Customer: “Do I really need to have my system maintained every year?”

Mullen Tech: “Honestly, yes, it’s a good idea. Think of it like a tune-up for your car. Annual maintenance keeps the system running efficiently and helps catch small issues before they turn into expensive problems.”

Customer: “That makes sense. I just didn’t know if it was necessary every year, or if I can remember to schedule this every time.”

Mullen Tech: “Totally understandable! A lot of folks feel the same way until they realize how much it can save in the long run—both in energy bills and avoiding major repairs. We offer a great maintenance program known as our Advantage Club, which gives you an advantage on any issues or worries you might have with your system by automatically scheduling maintenance visits throughout the year!”

What type of heating system is best for my home?

Customer: “How do I figure out what type of heating system is best for my house?”

Mullen Tech: “Great question! It really depends on a few things—like the size of your home, your energy efficiency goals, and your budget.”

Customer: “I’ve heard about heat pumps. Would that work for me?”

Mullen Tech: “It might! Heat pumps are super energy-efficient, but they work best in milder climates. For our winters, you might want to consider a furnace or even a dual-fuel system. When you are ready to schedule a tech visit, just give us a call!
