Signs You Need Heating Repair

Sudden heating system failure is rare. It’s more common for your system to show signs of trouble before it completely fails. If you detect any of these signs, we recommend scheduling a service as soon as possible:

  • Inconsistent heating capacity
  • Cold air blowing through registers
  • Odd noises/odors (screeching, grinding, banging, or moldy, mildewy, or burning odors)
  • Short-cycling
  • Yellow pilot lights
  • Unresponsive to thermostat controls
  • Poor indoor air quality

Common Causes of Heating Issues

Every heating system will eventually fail and require repairs or replacement. Most HVAC systems should be replaced every 10 to 12 years. Some of the most common causes of heating system failure we encounter include:

  • Clogged air filters and blocked ducts
  • Faulty wiring
  • Thermostat failure
  • Defective blower motor
  • Clogged ignition
  • Cracked heat exchanger
  • Blocked fuel supply
  • Bad fuses or breakers

Frequently Asked Questions

Can a cracked heat exchanger be repaired?

For safety reasons, repairing a cracked heat exchanger is impossible. Any repairs would likely leave minuscule gaps, allowing carbon monoxide to seep into your home. Replacement is the only option for a cracked heat exchanger.

How important is sizing a new heating system?

Proper sizing is essential for ensuring energy-efficient operation and system performance. If the system is too small, it will struggle to deliver the comfort you desire. This will increase wear and tear and result in premature system failure.

Conversely, if the unit is too large, it will short-cycle, you’ll lose out on any energy savings, and the unit will cost you more to operate than an appropriately sized system.

Will regular maintenance help reduce repair frequency?

Absolutely. Staying on top of maintenance will improve performance, enhance energy efficiency, and help extend the serviceable lifespan of your heating system. It’s a cost-effective investment in comfort, safety, and long-term savings.

What Our Customers Are Saying

"Adam Bunch and Salwan were our technicians. They were very professional, courteous, thorough, and we feel they did a very good job. They were both very personable, friendly, and genuinely take pride in their profession. We feel very confident in the work that they did. We have an older home built in the mid 1980s with old, failing hex water lines along with some copper fittings. We needed new lines installed and they did a good job with it. I would recommend them to other people. In comparison, the price is more expensive than some other businesses in this area for the same work, but we feel that the guarantee that comes with Pipe Wrench work brings accountability. We will use this service again in the future."

Amy C.

"Very timely. The first time I used this service I had a thermostat replaced in my hot water heater. They were quick and professional and was fairly priced. I'm in the middle of my second experience at a relatives home for hot water heater replacement. They were able to get a tech out for evaluation the same day we called (today) about a problem and have scheduled the replacement for the next day. The tech was polite, professional and advised us of all our options in a way that was easily understood. I highly recommend Pipe Wrench services."

Sasha N.

"Ryan and Tyler were fantastic! As soon as they got to our home they set expectations for all the work they were going to perform. They kept us posted on the status of the job throughout the time they were working and reviewed everything with us when the job was complete. They were professional, knowledgeable, and nice. I would highly recommend them and the team at Pipe Wrench for any plumbing needs! Although I hope we won't have to use their services again, if we ever have the need for a plumber in the future, they will be the first people we call!"

Katey M.

"They came on time with texts and calls ahead of time to ensure I knew who was coming (with a picture) and when they'd be there. Kyle was professional, personable and didn't try to sell me more than I needed. He worked with the scheduling to get me scheduled that evening, even though I couldn't be there for the install. The installation was prompt and they were clean (again with forewarning and pictures of who was coming). They are my new go to company. Thank you."

Mary W.

"Our technician showed up on time and very professional. This company never tried to take advantage of my older mom. Which some in the past have. Very thorough in explaining everything he did and the cost. They came the very next morning. My mom’s A/C had gone out the day before on a scorching hot day and week. I would highly recommend this company. Very good people."
