"I emailed HomeAdvisor for a AC repair at about 11pm last night. In the morning I had 3 companies sent to me by HA. I read the reviews and emailed 2. They both got back to me right away, one couldnâ t get to me until next Tuesday, the other called me at 7:45am and asked me what type of problem we were experiencing and that they could be at the house between 8:30-9:30am...that same morning! We said come on down and they were there at about 8:45, completed the repair and checked the system and gone in an hour. The cost was very reasonable. We would hire them again! Thanks Tom!"

"Same Day provided a bid on a system that perfectly fit my needs. The removal of the existing older system was not easy as they had to disassemble it to get it out of the attic, but Troy did an excellent job. The install of the new A/C and furnace system was done professionally and competently. Troy walked me through all of the new components, set the Nest WiFi thermostat, and made sure everything was operating efficiently. I'm very pleased."

"Great job. Anthony did a complete review of the house and the current venting and recommended the proper size for the AC. The installers and electricians came 3 days later, did additional wiring and piping and installed the entire system in 5 hours."

"On initial inspection, they discovered that our old heat registers were the kind with asbestos (house built in the 60's), so they had to sub out the abatement part of the job. Once abatement was complete, the workers showed up each day at the time they said they would arrive. They were all friendly and professional. They kept everything clean. The took pictures in the attic to show me before, during, and after the work. They explained what they were doing and showed me the new ducting they were installing (quiet ducts) and explained the more "up-to-date" way of putting in the duct work than what we had. After the work was complete, we noted that the furnace ran much quieter (due to new ducting), and it ran WAY less often. The house stayed much warmer while running the furnace much less often. Best of all, our gas bill dropped! Now that we're moving into summer, the house seems to be staying cooler on these warm days. We don't have A/C so we're hoping the new insulation will keep the house cooler as the days continue to warm up. Very happy with the company and all the work they did. I would recommend them!"

"So very happy with JMS West HVAC. Jim and Anthony were great. They worked around my schedule. They cleaned up after themselves. Stayed late one evening so that we had heat that night. Great value. Have recommended them to my neighbors. Great job guys!!!"

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.
