"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."

"First, my project was to install, from scratch, a new HVAC system, including ducting, with tha furnace in basement (initially, it was upstears in a closed). Last year and early this year, I got 3 contractors on site, by direct call, and none of them answered my spefic questions but taking pictures and promising that will send an estimate. I never got it. I was getting anxious. So I got the idea go to Angi. First visit I got in the same day I put my request on Angie's site, called his boss advice me to just change the furnace. I could not, because the previous system was heating OK only one half of the house. Finally, next day I got AJB visit an made me happy. He understood perfectly what I wanted and my concerns and explained to better and quite ingenious solutions on my suggestions. I understood him perfectly because I have strong knowledge of aero-dinamicsor or fluid mechanics so I signed the contract right then. Now, I have a sweet warm house in every corner of it."

"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."

"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."

Went above and beyond what was expected always stopping what they were doing to answer any questions we had.

W At your Service heating and cooling will be our go to for anything we ever need done!!!"

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.
