"Mull Brothers is great and i would recommend them highly. They do not require a contract and charge by the service provided. If you don't need a lot of service on your HVAC system it is the way to go. They are professional and always did quality work

"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"

"My furnace was not working over the Memorial Day weekend and the tempurature was unseasonably cool. Select Mechanical Services found that three items needed to be replaced. Since they didn't have the parts on hand at the time, they were able to get the furnace to work for the rest of the weekend and returned four days later and fixed the furnace."

"I don’t usually write reviews, but I felt like I had to for this one. I’d been dealing with an ongoing furnace problem for weeks and had a couple other companies come out but nobody could give me a straight answer or actually fix the issue. When Enea from Northeast Heating and Cooling showed up, he figured it out almost immediately. He was able to explain to me what was wrong in simple terms, fix the problem on the spot, and even made sure it won’t happen again. The technician was professional, thorough, and you could tell he actually knew what they were doing. After all the frustration I had before, their service was honestly a huge relief. Highly recommend them."

"Hiring Williams & Assoc. has turned out to be one of the best decisions Iâ ve ever made! From the very start, this experience was excellent! Bruce and his team were professional, kind, and helpful when describing the system we purchased and answering the hundred questions we had along the way. Their attention to detail and all of the little extras one wouldnâ t even expect to receive were provided as if it were second nature to them. And the team worked tirelessly, without stopping until the job was finished. We were happy to have them in our home. These are genuinely good people. Our old boiler was past the point of being dangerous. Smoke filled the basement every time it came on. Anyone could see that we were in an emergency position and had no choice but to replace the old system. Some companies Iâ ve dealt with in the past would have taken advantage of our situation. But not Williams! The price for our new high efficiency heating system was very â veryâ reasonable. Due to our situation, the work was started and completed almost immediately and the service was excellent! My wife and I highly recommend Williams & Associates."

"I have the Total Mechanical Systems Total Comfort plan. It is wonderful I purchased the Comfort Plan when we installed our HVAC System. This is a great service plan for a reasonable rate. You get check ups on your HVAC, electrical, and plumbing systems.,You also have access to repair services, electricians, and plumbers at a discounted rate. Great overall plan to maintain your home or condo. Recently I had my annual Furnace/HVAC check up. The technician, Marquez, was professional, knowledgeable, and pleasant. Marquez really knew his stuff and explained to me how my furnace works and what the telltale signs are that I might need repairs. Fortunately I have not needed any repairs thanks to their great maintenance plan!"

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.
