"I recently had a new HVAC system installed by Aireserv, and I couldn't be more pleased with the results. From the beginning, the team was professional, courteous, and informative. They arrived on time and were very thorough in explaining the detailed installation plan, the features of the new system, and how to operate it. The installation went smoothly, and the technicians cleaned the area while working. Once the system was installed, they ran tests to ensure everything was working perfectly and took the time to answer all of my questions. The new HVAC system has been a game-changer in terms of performance. It heats and cools my home more efficiently than my previous unit, and I've noticed a significant improvement in comfort and air quality. The system runs quietly and maintains an even temperature throughout my home. I also appreciate the energy savings I'm already seeing. My energy bills have been noticeably lower, which I can directly attribute to the new system's efficiency. Overall, I'm delighted with the service from Aireserv and the performance of the HVAC system. I highly recommend them to anyone in need of HVAC installation or upgrades. They provided excellent service from start to finish! A BIG THANK YOU TO ALTON THOMPSON AND HIS TEAM FROM AIRESERV."

"Alanis was prompt in their response to my request for our condenser replacement. We replaced our furnace 4 years ago, then our ac went out when it was 90° outside. John said it was over 30 years old so we decided to replace it. He gave us a great price on a 5 ton Bryant condenser. Best deal out of 3 other companies. The next morning, the team came out and were finished by noon when it started heating up. System works great! Thanks guys."

"I was extremely impressed with the service provided by Air Sharks, who replaced my aging furnace and damaged heat ducts. Elizabeth provided a detailed explanation in a friendly, professional and understandable way. Pricing seemed reasonable, and was 25% below a previous estimate. Daniel and his crew did a fantastic job removing and replacing the new furnace and the duct system in a very tight crawl space. They left the furnace looking absolutely beautiful and clean. I highly recommend them"

"Our water heater started leaking and needed to be replaced. Called in the morning and had someone out in the afternoon. This was actually our second quote. The first guy only gave the heater a cursory look before quoting a price. The Better Water Heaters technician actually examined the heater, plumbing and electrical connections before discussing options. We discussed replacing the original and switching to a tankless system. After we did some research and asked some friends who had a tankless system, we decided to go with the tankless. We scheduled an appointment for the next day and had it installed. Very smooth, very professional."

FAQs for furnace / forced air heating system install or replace projects in San Martin, CA

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.
