"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."

"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."

"Had a full HVAC system installed including all new ductwork. Maurice and Tanner and Bob were super professional and very informative. Went above and beyond what was expected always stopping what they were doing to answer any questions we had. Jason Bowen was extremely polite and professional explained the whole system we were going to get and didn't try at all to upsell equipment, and didn't pressure us at all for the sale. W At your Service heating and cooling will be our go to for anything we ever need done!!!"

"We came in to work one day, to find there was no AC in our offices. It was 90+ degrees that day, and as owner of the company, I saw that there was going to be little to no productivity that day. I called several companies, only to be told it would be a day or two before they could service our system. I was on the verge of sending everyone home, because the fans I purchased, just weren't doing the trick. Then, I called Paramount. Alan was at our offices within the hour. He determined it was a fan motor, and after a short trip to his office, had the new fan in hand. He also recommended replacement of a capacitor that he deemed to be on it's last leg. I figured he'd have to run to his shop again to get that, but he showed me a Full Stock of parts he had in his van. I'm in the Service Industry, and I have to admit I was impressed how stocked and organized his truck was. I was expecting a high bill, due to the response time and having to run back to his shop for fan. I was somewhat shocked how reasonable the bill was, and even added a little extra! Alan stayed around for a short time afterwards, and gave me some tips on what to do to keep my AC unit running efficiently. We have recommended Paramount to several companies and friends since this time, and they all have been pleased. We found our permanent Heating and Air company, and highly recommend Paramount to all. Thanks Again Paramount, and especially Alan, for doing a Great and Professional job! Russell with DTS Communications in Nottingham"

"The heating tech was very professional and courteous. I really appreciate how quick he worked to resolved the problem ."
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.
