"Sorry to be so late with this review. Just as we were preparing to leave town in mid-July, 2018 our air conditioner stopped working . We called Matthew Roberts. One man came out and worked for quite a while, he called someone else they both tried several fixes, but nothing worked. We had an idea of how much a whole new AC would cost so when they gave us a quote we were ready to decide. They came out and installed the entire Trane system, inside and out, in one day so it was working when we left town. Very professional, neat, friendly and took old system away. Since then we've had a couple of issues: a snake got in the electronics of the outside unit, shut it down and a couple of other service calls were handled extremely quickly and most with no charge because unit was under warranty. Michael was often the repairman and we were extremely pleased with his work and service."

"We got 5 quotes for the same job, and by far, Air 1 was the most competitive in terms of products being offered and price for services. Csaba and Joseph arrived as scheduled and immediately started working to remove the old system and install the new system. They were friendly, kept me informed throughout the process, and responsive to my numerous questions and inquiries. The office coordinator, Mike, kept me informed with emails and coordinated the final inspection efficiently. Excellent work and outstanding service for a great price! Thank you gentlemen."

"Outstanding! Louis was very professional, knowledgeable, and friendly. He took his time to explain the various pieces of the HVAC system, and made suggestions on maintenance. He followed a long detailed checklist, and pretty much tuned-up everything. Would definitely hire for future HVAC needs."

"Our dryer duct desperately needed cleaning, and so did our air ducts. However, our AC system is quite old, mildewed, and would dirty up the air vents again. Iron Air offered great deals to get our system replaced this week. Wow! We got the dryer duct cleaned out so now our family can run the dryer with confidence and efficiency. We are excited to get our new AC system installed tomorrow with cleaned air vents that will run cleaner than they have for many years. We are told the fee we paid for the dryer vent cleaning will be deducted from the overall fee to install the new AC system. Joe has been quickly responsive via text, which I greatly appreciate."

"I selected Wesley Whitson AC Heating Services over two other AC Contractors. He made my choice very easy. He was very knowledgeable and honest, answered any questions I had, never rushed or made me feel that I was taking up too much of his time, and always returned my calls very promptly. His price was all inclusive at a significantly lower price than my other quotes for an identical system, and he did not try to add any unnecessary items to the job, in fact, he gave me very good reasons why some of the items I thought I wanted were not really necessary. I also really liked the fact that his quote included the EXACT model numbers of the equipment he would be installing ! I contacted Wes on a Friday afternoon to to schedule the job (a new Amana Heat Pump and Air Handler to replace my dying 17 year old system), and he was able to schedule the job for the next business day ! His crew (Kyle and Zack) showed up on time and as promised, on the following Monday, to install my new system ! I am very happy that I went with the Variable Speed system with Humidity Control and ComfortNet thermostat. Wes was right about the Humidity control keeping things comfortable. We used to set our old system at 73 deg...the new system is set at 77 deg and 55% humidity (as suggested by installer Kyle), and it feels very comfortable (nice and quiet too) ! After the installation was complete, Kyle gave a very good explanation on the operation and settings of the ComfortNet Thermostat. I am VERY happy with my new system !"

FAQs for furnace / forced air heating system install or replace projects in Lake Mary, FL

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.
