Furnace repair

Furnace repair in Seal Beach

Most Seal Beach heaters sit unused for months, then get asked to work on the first cold night. Common calls we get:

  • The heater clicks or tries to start but will not stay on
  • It blows cold air, or some rooms stay cold
  • A burning smell that does not fade after the first run of the season
  • New banging, squealing or rattling noises
  • The thermostat is on but nothing happens

Smell gas? Leave the house and contact your gas provider.

Our tech explains the problem in plain English and lays out your options and the cost upfront. Repairs come with our 5-year labor warranty in writing.

Repair or replace

When a new furnace makes more sense

If your furnace is older and needs a major part, we show you both options side by side. Replacement estimates are free. Most furnace replacements we install run $4,500 to $5,700, about $5,100 typical, and Goodleap financing is available for homeowners who qualify.

Thinking about a heat pump instead? Our mild coastal weather suits them well. See heat pump services in Seal Beach or furnace replacement costs.

It was time to service the fan blower unit and had a pleasant experience again working with Glenn and his trainee George. I appreciated the time Glenn took to ensure George's work met the expectations that Glenn would have performed the job to. It's not often companies have seasoned experienced employees that can share their knowledge and experience with new staff. I hope Thomson keeps Glenn around for many more years!

Over the years, we've used Thomson to do major HVAC construction, equipment replacement and service. They are always very thorough, knowledgeable, considerate and the prices are fair. They have a lot of experienced technicians on their team and communicating with the office is easy. We get our system serviced every 6 months (very important) and they actually offer a monthly payment plan for that. I didn't take off a star (because they do offer a fantastic service), but it is difficult if something breaks during the weekend. They won't respond until offices open on Monday. But they will get you in as soon as possible and the service is great.

Very honest company and great customer service. It’s been a long time since we had our AC unit inspected and after all these years it’s still good to go and ready for summer! Ethan did a great job answering all my questions. Quick, efficient and very knowledgeable. Thanks Thomson!

Ethan was great and was very helpful in helping me understand the unit. He came out the same day I called and had parts on his truck to make the repairs right then and there. Ethan was very friendly and I would recommend him and Thomson Air Conditioning to anyone in the future.
