"The job went reasonably well. They completed it in a day and a half. The guys on site had a little trouble installing the high tech thermostat for the system, but their supervisor demonstrated real accountability when he showed up on a Saturday to make it right."

"I couldn't be happier with the service I received from McCrea Heating and Air Conditioning Services of Maryland. Upon returning from vacation on a 100 degree July day, I found my old HVAC system basically dead (90 degrees in my kitchen!) ... Shane immediately came out to provide an estimate, we signed a contract on the spot, and he kindly provided some freon to hold me over until the new system could be installed. Brian and Nick showed up exactly on time to install the unit, used drop cloths to protect my flooring, and were exceedingly polite and professional throughout. I'd highly recommend this organization."

"Just started working with Markool this summer and they have been fantastic! When I need service, they are so fast and every person we have interacted with has been polite, knowledgeable and personable. We unexpectedly needed to replace our system during a heat wave and they were super. So responsive and quick. I would highly recommend Markool for all of your HVAC needs!"

"Bought the Big Deal HVAC & Heating inspection to have the system checked. Supreme Air reached out the next day to schedule and was able to fit us in the same week. Chris called 30 minutes prior to arrival and within the scheduled window. Without having to ask, used shoe booties. Chris inspected and checked both systems along with inside & outside equipment. Spotted several small issues along with identifying the AC having low R-22. Was provided a quote for the repairs and notified they could complete the same day. There was an immediate difference in the cooling. Cannot say thank you enough. Chris is awesome."

"Sean was great during his visit to fix our furnace. He met us right away on a weekend, knew exactly what was wrong and repaired it for a very reasonable price. He was so good we asked him on the spot to do our twice a year furnace/AC checkups. Can’t recommend him highly enough."

"GAC has always done a good job maintaining my system. When it was time to get a new system, I was given four options by Eric, ranked standard to best. After each option was explained, I decided to go with the better option. The team of Matt, David and Sam arrived on time and did a fantastic job with the installation. When the job was completed, they cleaned up, explained the new system and answered all my question. I highly recommend GAC."

"I had a high efficacy heat pump system installed by ARS 11/2 ago. I am used to gas furnace so understanding how heat pump works is an education. The mechanic was very patient in explaining how it works and what to look for if there is an issue. Of course this cold season a got an high unexpected bill from the electric company and was baffled because of the amount I spent on this high efficiency unit. They came out looked at and found no issue. They explained this was a very unusual cold season and the unit performed accordingly for sub freezing condition. They did leave a card and said if I see anytjing that look unusual please give them a call asap. The mechanic was very knowledgeable."

"During the initial service visit, the representative (Xavier) gave a detailed explanation of the condition of the HVAC system and the repair options. I hired JDL and two days later they arrived first thing in the morning to install a new system (furnace and A/C). The quality of their work and products recommended are excellent. I highly recommend their services."

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.
