If you’ve ever experienced furnace problems in winter, you’re not alone. Cold temperatures and sudden freezes can adversely affect even the most durable furnace. Here are some of the most common wintertime furnace issues, all of which Comfort Air can remedy.

The Furnace Isn’t Creating Enough Hot Air

One of the most common reasons a homeowner seeks furnace repair in the winter is for a problem involving a lack of hot air. Or, perhaps the furnace is only blowing cold air. Both of these circumstances are connected, and can be traced to one or more of the following causes:

  • Uneven airflow: uneven airflow is the result of either having the wrong size furnace in the home, or the air ducts being improperly designed
  • Dirty air filter: your furnace’s air filter should be changed once a month, and no longer than three months at a time. If it’s been several months since you’ve installed a new filter, this could be the reason for lack of hot air.
  • Leaking air ducts: compromised hot air flow could be the result of a leak somewhere in your home’s ductwork, or the ducts may be intact but leaking air because they’re insufficiently insulated

The Furnace Is Producing Too Much Carbon Monoxide

If you have your furnace regularly inspected by our local HVAC company, you shouldn’t reach a point where the unit is producing excess carbon monoxide. However, if the CO sensors in your home are beeping, contact us right away. It’s likely that your furnace has reached an age where the heat exchanger is cracking and requires immediate replacement.

Noisy Furnace

A properly functioning furnace shouldn’t be clanging, banging, squeaking, or rattling. If your furnace is constantly making unusual noises, contact our nearby furnace repair company. A noisy furnace is indicative of a mechanical problem such as a clogged burner or abnormally low airflow.

Continuously-Running Blower

We all want to stay warm during winter, but when the air temperature reaches the temperature specified on your thermostat, the blower should shut off. If it does the opposite and keeps running, call Comfort Air and we’ll send a technician out to investigate. It could be that the furnace’s limit switch is malfunctioning or needs to be adjusted/reset.

Malfunctioning Pilot Light

There are several reasons why this might happen, including draftiness in the furnace area, cogs in the unit, and thermocoupling issues. All of these should be investigated by one of our trained HVAC professionals.

Cycling

“Cycling” is the technical term used when a furnace cycles through on and off modes as if it’s trying to find the right setting. Cycling is irregular and could be caused by a faulty thermostat, poor airflow, or a clogged filter.

Normal Wear & Tear

It’s always possible that this winter is the time when a home’s furnace begins showing signs of age. Evidence of aging include under-heating, overheating, poor/inconsistent airflow, and problems controlling the temperature from the thermostat. Our technician will confirm whether these problems are caused by age, and if so whether the best option is repair or replacement.

I was planning a heater upgrade and received a 24 month no interest offer from Home Depot. They sent me a list of contractors and Comfort Air was the only contractor that called me before I could call anyone else. The customer support, salesperson and installers were fast, competent and incredibly supportive. From the time that I contacted them until the heater was installed was fast and the new heater is a big improvement over what I had before. Highly recommend Comfort Air for fast, efficient and professional service. I feel comfortable that they will be responsive, should there ever be an issue with my new heater!

Bradford the technician has come to our home a couple times and is always professional. I especially appreciate the exceptional customer service in the office. Every time I call, no matter who answers the phone, they always help me and go out of their way to help me understand how to troubleshoot my thermostat/heat pump. Today, I needed to revise an appt time and Rosa called me twice today to make sure she set up the appt for a time that would work for me. Fabulous service!
