Hot and cold rooms
Is it possible to fix cold areas in my Seal Beach, California home?
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! Whether it is a simple air conditioning repair, or you need a new AC installation, you can count on us to solve the issue.
Our experienced technicians are trained to figure 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.”
Heating questions we hear
Seal Beach heating help, explained
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.
