"Mr. Dean was very professional and knowledgeable. He worked efficiently and didn't leave a speck of dirt behind. He went over the new furnace and central air system with me before leaving, making sure I was familiar with the new system operations. I recommend this owner operator company with high regards. Thank you!"

"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"

Customers say: Quality work

"Mr. Raffensberger was extremely knowledgaable and was careful to do everything right and to a very high quality. Fees were very reasonable. I'm exceptionally pleased with the new high efficiency boiler installed at a different location than the old one was in our basement. It was necessary to run a lot of new hot water heating lines, add a natural gas supply to the boiler location, and add air intakes and exhaust through the walls of the old brick farmhouse. The new boiler is heating at a far lower cost than the old oil boiler from the 1950's. Mr Raffensberger didn't cut corners. The installation and operation are great!"

"I have had problems with my furnace locking up ever since UGI-Miller worked on the gas line near our house. Rohrerâ s has been incredibly great, thorough and patient at coming out, trouble-shooting, and getting the furnace working, despite the problem probably not being caused by their system. UGI-Miller on the other hand, never responded to repeated calls."

"Had a new compete geothermal system and duct work installed to replace old oil furnace and coal stove. Installation team was top notch always professional and on time. Endured my on going questions through out the entire project which was completed very quickly with little interruption to normal house hold functions. A minor over sight required a service tech to come back out later but was also very professional and explained what happened and answered all questions. First time hiring a contractor for home work and was very nervous in selecting the correct company. No doubt I'd hire again and recommend to anyone looking for heating cooling solutions."

"Tash has done a great job! When I bought my house A/C unit stopped working. I searched for a local heating and air conditioner team. He was available same day, came out to check my unit and gave me reasonable quote for entire high efficiency furnace and A/C unit. I can say that he is well educated and knew what he was doing. Unit was ordered and installed with no issue. I highly recommend ATD Tech for Heating and air conditioning needs."

"I have been with another HVAC company for many years but last year had a problem with my oil furnace and it appeared they have lost all their experienced oil furnace technicians and could not sort out the problem with mine. I wanted to find an experienced oil furnace tech and I found Larry Price that owns Purified Air LLC. Larry came out and serviced and repaired my oil furnace a reasonable price for the upcoming heating season. If you need an experienced oil burner technician, Larry Price and Purified Air LLC is the place to go."

FAQs for furnace / forced air heating system install or replace projects in Stewartstown, PA

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.
