"Amazing technical expertise and physical strength displayed by Mr. Hall who got the water heater to second floor by himself and safely installed my brand new unit. He's also maintained my AC for the last 7 years and recently replaced my thermostat. He is also knowledgeable and able to make electrical repairs and wiring. He is also an honest person who will advise you accordingly."

"Core Mechanical replaced our aging air conditioning systems.  They were prompt, efficient, courteous, and professional. Their bid was quite fair in our estimation and below the competition. In today's world it seems a little unusual to find trades people who do what they say they will do when they say they will do it and Core Mechanical is one of those rare finds. I recommend them highly.

"The service went well. Two technicians came out and installed the system in 1 day. They were very nice, honest and down to earth. I did a lot of research and they had very good pricing. They were very knowledgeable and willing to come back for any adjustments.  I plan on using them again and had no problem scheduling with the company."

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

"We called Keys Mechanical to look at our central unit which was making sick noises and obviously struggling to cool our home.  We called them based solely on the Angie's List reviews.  As anyone who has lived in the Keys for any length of time knows, just getting someone to actually show up is a feat in itself let alone someone who is competent to do the job they claim they know how to do.  My husband called, set up a time for someone to come look at the unit and then we waited to see what would happen.  Low and behold an actual AC guy showed up, a little late but he did call ahead to let us know he was running behind.  In our experience, this in itself was remarkable.  It is not unusual for contractors/workers to show up late - after all everyone is on Key West time - but it is usually that they show up as much as 2-3 hours late without the courtesy of a call, explanation or God forbid an apology.  Oftentimes they just don't bother to show up at all.  We often wonder how they keep their businesses going without doing any work.  Anyway, they showed up, performed a diagnostic, gave us the bad but not unexpected news and then proceeded to put a "bandaid" on the unit to bridge the time between getting a new unit.  Gave us an estimate, told us the cost of the day would be erased if we purchased our new unit from them.  We did check out one more source of a new central ac unit; the differance in price was amazing.  In the meantime the "bandaid" while not perfect is certainly keeping us comfortable enough to sleep at night.  We will be purchsing our new unit from them; at that time will probably write another glowing review.

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