"I used them a few years before for another heating problem. They are not cheap but they are not over priced. They are reasonable. They are not the cheapest place in town, but they are reasonable and they do good work. I can't give them an A on price because they are not cheap. I would use them again."

"Excellent. Max arrived on time and got straight to work. He inspected the furnace, took measurements of the air temp and cleaned all the filters. He provided some helpful information for the potential future replacement of the furnace with options and estimates. Max was professional and personable. The total cost was as quoted. Other companies I contacted either would not give me a quote over the phone, charged to just dispatch a technician, or quoted more than double."

"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."

"I would give them 10 stars if I could. We were facing several technical issues to replace the original HVAC system in our home built in 1977. Angel assessed the job and answered our concerns. His estimate was a little below the average we received from other companies. He asked for no money up front. Other companies wanted close to 40% down. Working with the Ventwerx team was the best. They worked together to solve difficult ducting issues in our 2 story home. They did the work without making any visible cuts of the walls in the living areas of our home. This was not an easy job. It took a crew of 3 to 4 men five days to complete. The team arrived on time. Covered the work areas and spotlessly cleaned up at the end of each day. Their workmanship is clean and professional. The final cost was close to the estimate. Any addition costs were for items we added as the work progressed. The Ventwerx family is welcome in our home."

"The technician named William responded immediately. He came the same day. He carried out the inspection and fixed the issue for a nominal amount. He then sat down and showed me all the pictures of the furnace. He explained what was wrong. Excellent service overall. I will recommend him for anyone in need of assistance with their central heating and cooling systems."

"Absolutely the best HVAC company in the area. If you are looking for a company for your HVAC needs, look no further. It is superb in every aspect: customer service, onsite specialist who did the inspection and quoting, technicians who installed the system. Their price is extremely competitive, especially for the high end systems. I was shopping for a 80% 2-stage furnace but I ended up getting a Lennox 99% variable-speed furnace because the price was too good to pass. But it is money well spent. It is so quiet and powerful. I highly recommend Air Sharks. They actually put a smile on our faces."

"We had an excellent experience with Alanis Air HVAC. We are in an older house, and the installation of mini-split units with a heat pump was the most efficient solution to our heating and cooling situation. John, Santiago, and Jose provided expert installation. They were extremely efficient, and also tireless. Santiago and Jose came and worked into the night on several occasions to make this project work on time. They also handled carpentry and repainting. In the end we have an efficient, highly effective new system. These gentlemen were extremely pleasant to work with and totally accommodating of our schedule. I would definitely recommend them again. I should mention that this installation was a major economic commitment, and we are totally satisfied with the work and with the relationship we had with John and Alanis."

"We did a major renovation in our house and replaced the old gas heating system. Bobby did a great job of installing the new heat-pump based central A/C unit. He picked the right unit for our house and installed it along with all the ducts. He's also easy to reach to for any questions or maintenance requests. We've been using the system over a year and it's running great."

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