"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."

"Andy installed a new A/C, heat pump and furnace. He came out and checked out what we needed. He sent the quote that night and was back in less than 4 days to install."

"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."

"We decided to replace our 16 year old AC and furnace as we wanted to prevent possible problems with our HVAC system. The heating consultant that they sent, Alex H, was very friendly and knowledgeable. He provided us with estimates for a number of options - similar to those from other HVAC companies that quoted for this work. A day later I received a call from Blue Dot offering a discount on that quote and we accepted that quote. Alex made the one and a half hour drive to visit with us again, to walk us through the contract details, and to explain install process. This was a really nice touch as usually contracts are signed electronically these days. The Blue Dot install team came on time on the scheduled day and did a neat and professional job with the install - performing all the necessary checks and tests, and left the work area clean and tidy - and with the HVAC systems working well. The whole purchase and install process couldn't have gone smoother. We are very happy with BlueDot and will certainly use them again preferentially for our HVAC needs."

"Bryan and his team were punctual, clear about the order of work conducted, and all around professional. The tasks were completed in a timely fashion (over 2 1/2 days), with consideration of the fact I am working from home. They also agreed to wear face masks inside at my request, despite the heat and discomfort. More importantly, Bryan was very clear up front that his quote was just that: an estimate of the work to be done, with room for adjustment at the other end. I not only recommend BCG but I would hire them again should the need arise."

"Very professional and very knowledgeable. They preformed exactly as requested: quieted vibrations, fixed items that were missed at original installation, balanced system and eliminated duct noise when system starts and reaches desired temperatures. Also installed new controller and easy to use thermostats. Highly recommend."



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.
