"We called Grove Heating and Cooling and appointment was able to be scheduled for an estimate within a few days. Mr. Kelly came to provide estimate and give recommendations for lower level heating/cooling. Estimate was reasonable. The job was scheduled within one week. Workers arrived on time, were considerate of the newly installed carpet by wearing shoe covers. Worked diligently and completed the job ahead of the estimated time (6 hours instead of 8 hours). Cleaned the work area. Foreman for the job explained what had been done, showed me the completed work. Very professional. Would definitely recommend."

"It was a superb experience. From the visit by Bruce the sales representative to the installation day to the follow-up from Petro, every single person we interacted with was helpful and professional. When Bruce arrived to do the assessment, we spent time going over the heating needs in the house. After a thorough inspection and measurement of the house, we sat down. He showed me a few options, all of which were going to provide good service. I ordered a unit at the end of that meeting. The installation day was just terrific- the entire work crew that showed up were everything I would hope to find: Upbeat, informative, hard-working, focused. The job was finished before end of day as promised. The heater room is now immaculate, with new piping and a new heater. It was like watching a pit crew at a NASCAR race. Everyone had their tasks, they moved carefully but quickly. The materials were all laid out in order, etc. Just a totally professional approach to their work. The crew boss answered any questions I had. The follow-up for a normal inspection of the furnace chimney was scheduled the day after the installation. I’ve gotten calls to insure we are satisfied with the work. Satisfied barely covers it- I am pleased to write this kind of review. Without hesitation I will recommend Petro to friends and family throughout the Philly area. Peter A. Elkins Park"

"The technician was great. He explained what he was doing as he went along even though it was freezing outside. Checked my entire heating system to find the problem and replaced only the parts that were broken. Got my system back up and running in a little under two hours and was very pleasant and understanding when we asked him many questions and answered everyone so that we understood him. Thank you so much for your professional manner and courteousness. Got my hearing system to stop running in emergency mode and back to normal heat. Thanks"

"Ken was very professional. I called because my refrigerator was no longer cold. It turns out that Ice had built up on the cooling elements and had also built up on the circulating fan and so the fan was frozen and not working. Ken diagnosed the problem, and got rid of the ice with a heat gun. And the refrigerator was working. No parts had to be replaced. I was pleased with the service and the job that was done. I thought it was a little costly - $234 for one hour job."

FAQs for furnace / forced air heating system install or replace projects in Dunkirk, MD

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.
