"I was able to get a same-day appointment, and Abraham showed up right on time. He took a look at the system and confirmed that the furnace was running as expected, and he didn’t find evidence of a cracked heat exchanger. I was hoping for a definitive answer as to why the air wasn’t flowing out of several of my vents, but he was only able to confirm that it wasn’t due to the furnace itself. I may have clogged or separated ductwork behind the walls, but he wasn’t able to diagnose/confirm. At least I know the furnace itself isn’t the source."

"During the hottest week in several years, THEY SAVED OUR BACON by 1) responding, 2) promising and 3) delivering. Specifically, they showed up on Tuesday, installed the new compressor on Wednesday, removed the defective valve in the attic (not an easy job with our outdated ductwork) on Thursday and installed the OVERNIGHTED special order replacement valve on Friday. New system works great. FYI, other numbers we called during the emergency said, "two weeks at the earliest.""

"This company was without question one of the best we have worked with. Polite, honest about the work to be done and the time frame to get it done. Our Navien boiler/heat combo went on the fritz during a major cold snap and the holidays, a double whammy. They came out that very day. Jared was our technician, he was awesome. Kelley's was able to get the needed part to fix the issue the next day. He came back not only fixed the problem, but waited for 30 minutes before departure checking the system and making certain everything was running as designed. Since the combo system went down during such extreme cold days, extra pressure built up that didn't present itself until the next day. We texted Jared, he not only responded to the text, he called us immediately, on a Sunday and walked us through what turned out to be a simple fix. Things have been running smoothly ever since. Jared was awesome. This is our families team FOREVER!"

"I had lost water pressure on Saturday and made a emergency call to a unknown company from google. I talked to a person immediately from Cassidy Plumbing and was told I would get a call from an employee in one hour. An employee called and would come over in 15 minutes. I was amazed at the response time. He check out my water system thoroughly and told me that I wasn't getting water in the well tank causing me to lose pressure but also I was not getting any pressure straight from the well either. It was either the water pressure tank with the pressure switch or the water pump that was causing this problem. The pressure gauge was also broken. He explained fully what needed to be done, the price for each issue and since he was not able to do anything until Monday, I was first on the list.
Cassidy Plumbing called me in the morning and told me that they would be their in one hour. They came promptly and went to the well tank first and found out the pressure switch had corroded and the well tank was also not doing it's job. The tank was about 15 years old and the switch was more than 25 years old. I was told and saw everything that needed to be replaced and the price. When replacing the valve close to the water filter housing the piping broke off and upon looking at it this was corroded too! I was able to get a discount for the water filter housing since they were working on that section of piping and it was unexpected. Afterwards they tested the water pressure to make sure all was working and that the register near the pressure switch was functioning.
My water room is the size of a closet. Inside is the water heater, water softener system (tank for salt and two tall cylinders), electrical box, telephone box, cast iron plumbing for toilet and the well tank. It was tight to say the least and they did a neat job of putting everything together and cleaning up.
I have had to replace my well pump and another time the electrical wiring to the pump and both these companies could not compare to the professionalism and services that Cassidy Plumbing and Heating."

FAQs for furnace / forced air heating system install or replace projects in Darien, CT

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.
