"Just had my first service check up on my heating and air conditioning unit. As was the install the scheduling was easy. The technician called prior to arrival. I met him at the door and he explained everything that the service included. Then he went about his business. The report was concise and I am extremely pleased with his professionalism and manner. I highly recommend Maynor for your installation and service needs."

"Carolina Comfort installed a new HVAC system at our home. They did a great job from the original recommendation on the type of unit- a ducted split system- to a quick scheduling of the work- and lastly installing the system. Ryan, Dylan and John were great- very polite and professional and got the system and fully installed and running within the time frame promised. Would definitely use them again."

"We can't say enough good things about Gand M. The amazing thing is that a tenant found them for us on a super hot summer day when a solenoid went out and the people we called couldn't see us for a day or two; Gand M was able to show up that day. They also fixed the problem for a reasonable price.
Since then, they've consistently shown top-quality service and support. Some examples of unusual situations:
- A system in a condo where the electric bill was nearly $200 in a mild spring month. After several hours of diagnosis, the technician discovered a wire short that was causing both the heating and cooling to turn on simultaneously. The charge for this was minimal as it turned out there was no actual part to replace. Although I don't recall the actual charge, I do recall feeling they were more than fair.
- A zone board in a multi-zone, single unit system failed. They diagnosed the problem and jerry-rigged a solution that kept the unit heating the house, only on one thermostat instead of two. A reasonable solution until the zone board (which has been discontinued) can be replaced. Not a cheap repair at $279 but not outrageous either; it did take several hours. The unit is still working 3 months later.
- An emergency call in a townhouse on a 98-degree day with a toddler in the family on a Friday past 6 pm. As it turned out (partially luck, I'm sure), a technician was in the area and it was fixed - not just diagnosed but FIXED - within 2 hours. I had cautioned that a repair probably wouldn't be possible until Monday...but Gand M really came through.
i've recommended them to several people and I know at least one continues to use them for semi-annual maintenance.

"The company was very responsive and quick to get someone out to check the problem with our furnace. Once we decided on replacement, they got us on the schedule immediately and completed the job within a day.  All crew members were pleasant and professional and made this a terrific experience.  We have used Advanced in the past for refrigerator repairs and have always been extremely happy with their service and prices.  Will definitely use them again!"

"Craig and his team were fantastic. I initially contacted them for a service call, but we ended up replacing both of our AC units and furnaces. They arrived when they said they would, were friendly and respectful and cleaned up when they were done. Highly recommend them!"

"This company was excellent from start to finish. We needed our hvac unit serviced and they were efficient, knowledgeable and kind. I called needing someone out same day and they arrived very promptly. I received a text letting me know when to expect them and I didn't have to wait around all day. The technician was able to fix the issue and also took extra time to thoroughly inspect each unit. I knew before any work was done what the cost was going to be and there were no surprises. I was so happy with their service that I had them inspect the heating and AC system our new house that we were purchasing. I highly recommend Streamline Services."

FAQs for furnace / forced air heating system install or replace projects in Cary, NC

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.
