"The technician was extremely thorough. Replace the thermostat batteries and furnace filter (I provided the parts), checked for any carbon monoxide leaks, checked the condition of furnace components, and found some bare wires that he taped up."

"We contacted Pure Air for emergency furnace/boiler repair in our home and we ended up having to replace the unit. They recommended a combination hot water heater/boiler unit and we decided that was the way to go. The work was done very well, and all of the folks from the company were professional, courteous, and knowledgeable. The installation took a little longer than expected, so they even came back on a Saturday to finish the job. I had a couple of questions after and sent an email and they responded right away even though it was a Sunday. We're so pleased with the new system and the work that the Pure Air team did, that we will use them for all of our HVAC needs and will happily recommend them to others."

"GLM Mechanical Services, Inc. installed a new heat pump and air handler HVAC system at my residence on June 10, 2015. They arrived on time and completed the installation for the price that was initially quoted, without trying to upsell me on any additional services. On July 07, 2019, I needed to locate a part for my HVAC system and contacted GLM Mechanical Services, Inc. for assistance. They promptly contacted me back and located the part that had to be specially ordered from Texas. When the part arrived, the owner of the company picked the part up from the vendor and hand-delivered it to my residence. I highly doubt that I would have received this type of customer service form the other well-known publicly traded HVAC companies."

"Isak was of great help in servicing our 15 y/o forced air and heat pump furnaces. He described every step of the service, taught us how the units work, and where to look for early failure. Isak also helped install and properly program our Nest thermostats so we have an efficiently running house and HVAC system. Would highly recommend to anyone looking for help!"

"Mr. Bost did an excellent job for me for a reasonable price. I know he obtained the best deal for me on the furnace and the air conditioning unit. He answered all my questions. He was on the job when he said he would be; he was professional and courteous. The installation went smoothly, and I have had no problem with the furnace or air conditioner since they were installed in 2008."

"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."
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.
