"I couldn't be happier with the service I received from McCrea Heating and Air Conditioning Services of Maryland. Upon returning from vacation on a 100 degree July day, I found my old HVAC system basically dead (90 degrees in my kitchen!) ... Shane immediately came out to provide an estimate, we signed a contract on the spot, and he kindly provided some freon to hold me over until the new system could be installed. Brian and Nick showed up exactly on time to install the unit, used drop cloths to protect my flooring, and were exceedingly polite and professional throughout. I'd highly recommend this organization."

"Our heat pump was making some strange sounds and we called and had an appointment right away! Isaiah was prompt, courteous and professional! He gave us a couple of options to help us with our heat pump issue. We opted to replace the heat pump and furnace and have peace of mind for the next 10 years. During install, Isaiah, Joseph and Michael all did a great job, they all were very professional and would definitely recommend them!!"

"One zone of our two-zone HVAC system was not cooling properly.  First, we got an estimate from a different vendor who recommended replacing the entire system (interior and exterior) without even attempting to diagnose the problem.  We decided to get a second opinion and a neighbor suggested we contact Charles at Ocean Breeze.  "HONESTY & INTEGRITY" is the name of the game for this company.  Charles came to the house to investigate and first checked the interior unit to make sure there were no leaks.  Then (according to my husband - not sure I have this exactly right), Charles disconnected the lines from the interior and exterior units and pressurized them to check for punctures or other signs of leakage. 
After doing a thorough examination of the possible causes for faulty cooling, Charles recommended replacing only the outdoor unit.  He took his time, examined the system thoroughly, consulted with my husband each step of the way, and replaced only what we needed.  He was in our home 2 or 3 times without us being there and could've taken advantage ... but he did not.  We were very impressed with his honesty and thoroughness, and would seek his help again in a heartbeat!  Happy to write this review!  (And thank you, Erik, for the referral!)

"From the initial contact with Rob at Shore2shore, the experience was nothing short of wonderful. He spent considerable time evaluating my home and listening to my needs, then guided me through every step of the way with care and professionalism. I would 100% recommend this company to my friends and family. I'm very happy with the short time it took from the initial contact to the job completion for the heat pump system. Great job!"

"I had a great experience with Nate. He was extremely knowledgeable about A/C systems and was far more well-versed than many other companies in the area. He took the time to explain everything clearly, answer my questions, and make sure I understood the issue and solution. Nate was also very friendly, professional, and informative throughout the entire visit. I truly appreciated his expertise and excellent customer service. I would highly recommend Nate to anyone needing HVAC service."

FAQs for furnace / forced air heating system install or replace projects in Fenwick Island, DE

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.
