"My neighbor and I looked into ductless heating and cooling and noticed that Air Tech had great reviews and I know why. We both hired Air Tech after interviewing other companies. The work was completed on schedule. The technicians were courteous and respectful and spread cloth on the floor in the rooms they were working. Anytime I had questions they were more than willing answer them. Even the secretaries in the office are great. I would highly recommend Air Tech."

"I have NOTHING but GOOD things to say about MSP. Professional, fair, reliable and kind. Angel, David, Brett, Luis and everyone on this team go above and beyond to explain what needs to be done, and they take serious pride in their work. I'm picky about companies I work with and will 100% be referring them to anyone who needs heat/air services. We have now replaced our entire system with MSP and enjoy their whole crew. I'm very particular about our home (Italian and very ocd) and they leave my home in perfect condition every time they've left. Happy Holidays MSP. You folks are stand up people and we are beyond grateful!!! You have clients for life."

"McLay Services did an excellent job on the preventative maintenance for my A/C system. Dylan was professional, courteous, and thorough throughout the visit. He replaced two air filters, cleaned the coils, and checked all electrical components to make sure everything was running safely and efficiently. My unit is now healthy and fully operational. I really appreciate the quality of work and attention to detail — I'd definitely recommend McLay Services to my friends and family!"

"HD MECHANICAL! I don’t even know where to start, Chris and his team were went above and beyond when doing work at my house. They were honest and and caring which you don’t see from a lot of companies now a days. My wife and i weren’t sure which direction to go in as far as picking a unit to the whole installation process and what we would need. They walked us through it all and were very comforting as they explained every step of the way. I will 10/10 use them again and recommend it to anyone who is needing A/C and heating!"

"Ray is very professional, and provided options for my air conditioning unit replacement. Ray went out of his way to replace a small gas line leak that he found. He also drove to Anaheim early on Saturday morning to pick up a part that was needed for the AC unit, and came over to install it so that I would have the air conditioner available for the upcoming heat wave this week. He and his team were on time, and considerate during the installation process. I highly recommend RS Air Conditioning & Heating."

"The Tech went above and beyond to do my inspection and service. I did nor buy the yearly maintenance plan and I did not buy the $190. furnace filter ($20) at Home Depot. I had and still have a problem with the system. It makes a growling noise every 2 minutes or so. Thanks so much, anyways."

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.
