"I have had a service contract with McCrea Heating and Cooling since I purchased my condo unit new 7 1/2 years ago which included 2 maintenance visits a year. My current contract expired yesterday so I called to renew my service contract and upgrade from "Bronze" to "Silver." The representative took my charge card information over the phone. I asked if the contract was in effect as of today. They said "yes." Then I tried to schedule a service call (my unit was serviced a little over a month ago and now the condo wasn't cooling.) I was told then that the Silver Contract would NOT be in effect after all. The difference in price between Bronze and Silver is the cost of a diagnostic visit so they were getting the money one way or another. My long time history with the company did not persuade them to honor the contract I had just paid for. They wanted to charge me $98 to have my problem diagnosed under the Bronze contract that I pointed out was already expired. I was told the representative "misspoke" and should have told me they would have to send out someone to determine whether the furnace they have been maintaining for the past 7 years (with the most recent service call just a month ago) would "qualify" for the Silver plan. So, I cancelled the order for the Silver Plan. I called another company who came out for $30 and determined the problem was a clogged condensation drain. This drain was supposed to have been "blown out" when the regular maintenance was done by McCrea just a month ago, but obviously was not. The water was backed up in the drain pipe and filled the pan under the furnace/AC unit which turned off the AC. Now that everything is working again, I am seeking a different maintenance service plan provider. McCrea has competitive service contract prices, but if they have no customer loyalty, and the maintenance work is not done properly, maybe it's a question of "you get what you pay for.""

"Josh came to provide an appraisal and he quickly understood what needed to be done and provided a solution. Jose came out quickly and widened the opening so we could get our furnace serviced and our heat turned on. Jose returned and within 4 hours had the electrical outlet moved, new framing complete and painted, floor tile replaced, and new doors installed. I am very impressed with the service provided by JW and will contact them again for any needed repairs."

"Especially for the price (I'm doing another installation now and can't find equivalent), no issues whatsoever. The bathroom I had the toilet installed in is not very big, and with a small radiant heat unit on the wall, it's a cramped space for doing the installation. But it was done well, and the new toilet has been working fine with no issues. I dealt with disposal of the old toilet, but that was fine."

"The team came out on short notice and was able to get our HVAC system up and running. They were able to trace a problem of a short on a wire at heat pump, then found that this had also shorted out the defrost board, which in turn fried the transformer and thermostat. Instead of giving up and telling us to get a new unit they traced all the issues. They did an amazing Job."

FAQs for furnace / forced air heating system install or replace projects in Saint Marys City, 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.
