Is it Possible to Fix Cold Areas in My Seal Beach, California Home?

We serve Seal Beach the best, because it’s our home! - Thomson Air Conditioning

When one specific area of your home is not the same temperature as the rest of the house, it can be frustrating to figure out why. Even if you know the problem, finding good solutions that won’t break the bank are tough!

That’s where we come in. We are experts at figuring out the best way to solve your problem. We can zone your current duct system, relocate vents / ducts, add registers, install additional sensors and thermostats, adjust airflow to circulate air throughout the home better, and even install a ductless system to serve just the trouble spot.

A note from the owner, Josh Thomson
“In my home in Old Town Seal Beach, we opted to use ductless mini splits to heat and cool only the rooms that we were in at the time. We found that heating the entire house when we were only in one area at a time, was not the most efficient way to do it. Some of our neighbors have done the same thing and loved it! But I’d imagine each home here has a very unique situation. We also hooked our thermostats up to WiFi so we could adjust the temperature throughout the house from our phones. This is also helpful if we leave home and forget to turn them off.”

Why Does My SB Home Have Smelly Air Vents?

There are many reasons the ductwork for your heating system can become smelly.

Sometimes it’s just because we don’t use our heat very often at the beach. The Pacific Ocean keeps our climate pretty mild most of the year. So when you decide to turn on your furnace or heat pump, sometimes there’s a smell. Since every home is different, often we need to inspect the system to find the reason for the smell.

High humidity along Orange County’s 405 freeway (usually from the ocean air) can lead to mildew and mold. Usually this can be cleaned easily. Pictures of your system and any trouble areas that we find are presented to you in a low-pressure and no-hassle way. We do this only to inform you of what is causing your issue. From there, we present you with options to repair, clean or even replace the affected components.

And whatever option you choose is available with our flexible payment plans, so you can decide to handle your heating systems needs in the way that suits you and your family the best.

Is There A HVAC Service Company in Seal Beach to Diagnose Why the Heater Won’t Turn On?

A member of our team can come to diagnose the issue for you.

We’ll quickly identify the problem and provide you with many options to remedy it. When we are in your home, we will discuss what you have been experiencing and ask you a few questions.

From there, our techs will then get to work on your system to diagnose the issue that is creating the symptoms you have described. Once we’ve found the problem, we will take pictures (if helpful) and show you.

We explain everything to you until you are comfortable and understand what took place and what went wrong. We will lay out every possible option to fix the system as well as any other options you would like to see.

Because every system and every person’s needs want and desires are different, we will let you choose how you would like to proceed. After you have been shown pricing and have approved a solution, we will get to work.

We will never just do work without your approval and stick you with a bill that you haven’t already approved.
Again, with Thomson Air Conditioning working for you on your home’s heating system you are always in full control.

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!

15/05/2025

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.
