"I own a business and had a company come out to fix our air conditioner. They came out 4 times, charged for all those time and the unit still was not working properly. I then decided to try someone else, so I called Thermotech on the referral of a friend. They came out, diagnosed the problem within 10 minutes (it was an old crumbling circuit board), showed me that bad part, ordered it and had it fixed in less than 24 hours. We have not had a single problem since! I was so happy with their service that I ended up using them for my home HVAC system.. I even referred them to a family member and they did a home install of a brand new HVAC system and they were very happy with the price, install, workmanship & fair pricing. Thermotech has found a customer for life with me. I have had so many bad experiences over the years with other companies telling & thermotech has been a game changer."

"Furnace ran without trouble while Eric was here. He inspected it and ran tests, found nothing wrong. Charged us only for the visit, and didn't try to sell us any kind of additional services. But he provided a quote for a new unit in case the noise returned and we wanted to replace the furnace, which is 20 years old. The noise returned, and we will have Eric install the replacement in a couple of days. We are happy to be repeat customers because he was professional, prompt, and helpful during the first visit."

You won't find a better computer technician/computer builder than Jim Ferrell. I have been using his services for years and he has come to my rescue many times. When my computers crash, he helps me recover my data when no one else can. Recently he built me a computer specially designed for my needs and it works great. He got me better quality parts than they give you at places like Dell, and at really great prices. He has made house calls for me before and he has fixed my computer remotely via Internet access many times, which is very convenient. Other companies on the Internet claim to provide computer repair service via Internet access, but many of them are scammers (I have fallen prey to that myself, and my computer crashed as a result) but Jim is honest and trustworthy, so know that you don't have to worry about him taking advantage of you in any way. He will even take the time to teach you how to avoid scammers and other malicious things like viruses, which most computer technicians won't do. I recently purchased his monthly maintenance services. Every month he checks out my computer via the Internet and scans for anything malicious and looks at the overall function, and now I can rest easier knowing that Jim is watching over my computer's health. In today's world, you may feel like there is no one you can trust with your computer, your data, your personal financial info, or even your identity, but Jim is one person that you can indeed trust.

"It’s been a while that I wanted to have a company that can come over and check the house for any problems that increased my monthly bills and to fix them at a normal price. I came across this company and I scheduled a meeting with Ezra and Charlie to come over and see/check. Ezra and Charlie checked the house for more than 2 hours and they found out that some of the windows were old and needed to be replaced with new ones. In addition to that, they recommended me to remove the water heater and to install a tankless system that will provide me with hot water only when I need and by having that, my bills will be reduced.The Quote that I got from him was good enough (to my opinion) and I retained them for the job. The work that they did proved to be good one and I see that in my monthly bills. It was a 2 weeks work and I am completely happy with my decision to hire them."

"Alan was the installer that I dealt with in replacing a dead air-conditioner that was 16 yrs. old. He did a great job . . . very professional and would recommend him to anyone else with heating or air conditioning issues. It's been over 3 months since the installation and so far have not had any issues. I think the reason that Sears gets a thumbs-up in this is because they out-source this service. I've had issues with Sears in the past . . . but it seems when they are not directly involved in the product . . . they do do a great job of finding someone who does a great job."

"They were easy to schedule with and they came when they said they would. They got the job done quickly and we had no problems with the tinting. It has helped to lower our heating and cooling bill. They got the job done in about half a day. Their prices were very competitive."

FAQs for furnace / forced air heating system install or replace projects in Douglas Flat, CA

Converting from an oil furnace to an electric furnace isn't a simple swap—the oil system needs to be completely removed before installing the electric furnace. You'll need a full electric system installation, but you might be able to reuse existing ductwork if it's up to current safety standards. You’ll need to budget for a new electric furnace installation, which costs between $1,800 and $6,200, including professional removal, proper disposal, and safe installation of the new system.

Electric furnaces are 100% efficient at converting electricity into heat. However, some of that heat can be lost as it travels through your home's ductwork or escapes through poorly insulated areas. That's why regular duct maintenance and proper home insulation are important to maximize your furnace's efficiency and reduce heat loss, ensuring consistent warmth and lower energy costs.

With proper maintenance, an electric furnace can last anywhere from 20 to 30 years, outlasting the average gas furnace's lifespan of 15 to 20 years. To keep your electric furnace running efficiently, schedule regular cleanings, tighten connections, and have inspections done before winter arrives. With routine maintenance, you’ll ensure consistent, safe heating for years to come.

The size of the electric furnace you need depends on factors like your home's square footage, climate, and insulation quality. As a general guideline, those who live in warmer climates should multiply their square footage by 30 to 35 BTUs, while those in cooler areas should multiply it by 50 to 60 BTUs.

Consulting with an HVAC professional can help you determine the exact size that's right for your home.

An electric furnace works by converting electricity into heat using high-resistance heating elements. A blower then pushes the warm air through your home's ductwork, distributing heat evenly throughout your space. Since there's no combustion involved, electric furnaces eliminate the risks associated with gas furnaces and provide consistent, reliable heating when properly installed.

An electric furnace uses between 40 and 80 kilowatts per day to heat your home. The exact amount it uses depends on factors like your home's size, insulation, and overall energy requirements. Larger homes or those with poor insulation use more energy than smaller, well-insulated spaces. A professional furnace assessment can help confirm the ideal unit size for your needs.
