"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."

"We recently had Mega Power Electric Inc install a solar system and panels. The President and provided excellent communication all the way through the process. He even met with us after installation to explain the almost incomprehensible PG&E bill. Although not the least expensive bid, his was competitive and I felt he was as interested in educating me about solar and the various types of panels and inverter systems as he was in selling a system. He demonstrated how the array of panels would meet our energy needs and as opposed to some of the other companies, wasn't selling us more than we needed. We are very satisfied with our solar system and I highly recommended Mega Power Electric Inc."

"Computer did the "gotta send info to Microsoft" but when tried to reboot it ran through automatic repair without success. I did all the alternative without any success. He came and picked up the hard drive on Tuesday and returned it on Saturday. Fortunately he was able to "restore" without any data loss. Very happy with outcome."

"I interviewed six solar companies and got bids from three. Charlie of Landmark construction & energy crew stood out much more above the other companies that I spoke and met with. He is responsive, always returned my calls quickly and he does what he says he is going to do. Charlie came over to my house and met with me before installation, during the installation and after. In addition he worked with his crew at the beginning of installation to make sure everything was perfect with a tricky area of my roofline. Above all of what I wrote above, Charlie and the office staff are very organized people. Charlie was able to provide me with a lot of information about rebates, taxes etc… and Every bit of information I could want related to monitoring my system, working with Landmark construction & energy crew, maximizing the cost benefits, and getting my tax rebate, are all gathered and clearly labelled in a binder. Charlie knew how to explain everything about solar and I could see during our meetings how much patient he have. Charlie didn't have to push anything in order to sell his work to me because his product was the one I wanted, it made sense, and the price was better than others. I can't think of a contractor and I've worked with quite a few once in the past and for this project, I met with several ones as well and Landmark construction & energy crew is more reliable, efficient, and customer-oriented. Thank you, Charlie!"

"I had to remind them to clean the dryer vent
a lot of tiime was spent trying to convince me to buy a fancy UV system for cleaning my HVAC, which I didn't want
I just wanted them to perform and service and leave -- I didn't sign up for a sales pitch

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.
