"Smart Heating and Air Conditioning was the most professional, friendly, and knowledgeable company I’ve worked with. From our first contact, we felt like we were working with family. Our furnace went out and the techs and installers were all so amazing with keeping us all informed, especially Susie who works in the office. But what really showed me how great this company was, is that they saw our handle to our screen door wasn’t functioning and they were so kind to offer to fix the issue. They fixed it in 5 mins. You don’t see this type of generosity anymore, so we appreciate that! Our furnace and air were replaced for a great price and we couldn’t be happier. I would highly recommend this company for your heating and conditioning needs!"

"Albert Nahman PHC installed new AC and Furnace for my house. I like them for several reasons -- 1. At first Tom explained in detail what equipment I need and how they work, and gave me a reasonable and detailed quote at end of the visit. 2. They offer interest free finance. 3. I got free upgrade for furnace when the original quoted is not available. 4. Their installer did good job, and cleaned up afterward. I highly recommend this company."

"I had been using another company and bought an A/C system from them and there were problems. Josh explained the previous company did not install it correctly. He identified and corrected the problems with the previous A/C installation and installed a new A/C system and gas furnace as well. He was very professional, easy to trust, and he did everything he said he was going to do and was on time. The price was reasonable and he is honest and has integrity!"

"Peter, and his crew, were very reliable and professional. I purchased a new RUUD furnace and A/c. Their price was better than the other 3 bids I got. Everything was inspected by Archon. The final permit/inspection was issued. The system has been up and running for 6+ months now. No problems."

"Juan and his team were top tier professional. From the initial consultation to the hvac installation, they handled everything with care. Juan was so thorough answering my questions, the install was done in time, and everything was to spec. When I contacted him with an issue after install, him and his business partner came to take care of things immediately. I wouldn’t hesitate to recommend them in a heartbeat. So grateful for the work they did with removing our furnace and installing a split unit heat pump. Thank you Juan!"

"I called ThermoTech Solutions and they sent out a technician within 24 hours. I was pleasantly surprised that the technician was the same gentleman I talked to over the phone so I did not have to retell what was wrong with my system. Jason my technician who is also the owner was great. He tested my system, knew exactly what was needed, and had it repaired the very same day. He did not try to sell me on upgrading my unit or a bunch of repairs I did not need. The service was fast, very reasonably priced, and I have had no issues since. Will definitely be having ThermoTech Solutions come out for all my HVAC needs in the future!"

FAQs for furnace / forced air heating system install or replace projects in Knightsen, 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.
