"The replacement of my a/c ( with indoor coil) and furnace was handled in an extremely professional way. Holtzople Heating and AC helped me to find the best replacement units for my 20 year old Trane system. I am impressed with the knowledge of the sales person sent to provide quotes. I am also impressed by the skill and meticulous care that the installers took while replacing my entire heating and cooling system. Within a day, they took out my old system, installed the new system up to factory specs, tested and made sure all phases of heating and cooling were functioning as they should, and cleaned up, taking away all of the old unit, leaving nothing behind. The last thing the head installer told me was that a quality control team would be in touch and be coming in within the next two weeks to make sure everything was continuing to operate as it should. This attention to detail, and customer satisfaction is what has impressed me the most about Holtzople Hearing and A/C."

"Everyone from Presidential has been friendly and helpful -- great customer service! Glenn came to our home to discuss options to replace our furnace (fuel oil) and AC systems with a heat pump. He immediately understood that we were looking for a heat pump eligible for the new tax credits (unlike another company, who only provided estimates on what they had in stock). He prepared the estimates for 3 different models on site, and he noted that the heat pump eligible for the tax credit would cost about the same as an older model (unlike what the first company told us). We were able to schedule installation quickly, and then the adventures began. Harvey and Andre were here for 12+ hours...because a wire was either never connected at the factory or came loose during shipping. We also had to replace a defective line from our house to the unit. While it was a complicated install (not the fault of Presidential), we rec'd great service from hardworking staff members. Highly recommend!"

"Furnace was not operating because the company's automatic delivery system ran me out of oil.
Technician showed up promptly and got the furnace operating but could not get heat into the house. Had to reschedule to have zone valves replaced. Technician show up late and didn't have the required parts. Had to reschedule again.
The third technician showed up on time with all the correct parts and worked most of the day to get the system operating properly.
He was completely knowledgeable and very conciencious that everything was working correctly.

"I was having problems with my air conditioning system and arranged for McCrea Heating & Air Conditioning Services to send a technician to my house during the afternoon of May 1, 2018. On that date a company representative called me to tell me when their air conditioning technician would be arriving and Dwayne, the technician, arrived on time. Dwayne did a comprehensive inspection and assessment of the inside and outside units that comprise my air conditioning system. He patiently and carefully explained to me what he was doing, and what his instruments showed was the status of my air conditioning system. He made some adjustments to my air conditioning system. In addition, at my request he injected a product named A/C Leak Freeze into my air conditioning system. He used this product at my request and not because he was trying to sell me this product. I am very pleased with the level of knowledge and professionalism that Dwayne demonstrated while servicing my air conditioning system. I highly recommend Dwayne and McCrea Heating & Air Conditioning Services to others."

"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"

FAQs for furnace / forced air heating system install or replace projects in Knoxville, 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.
