"I purchased a mini-split AC system online and Ricardo installed it. Usually, a unit is purchased through the installer, but he was willing to work with me and just charged me on the labor for install and testing. He did great work and was priced fairly. The unit is up and running well and I couldn’t be happier. I highly recommend hiring him and I will do so again if I have future needs!"

"Efficient is the perfect word to describe this company. A highly professional installation team arrived early in the morning and the job was completed prior to noon. We had a new HVAC heat pump system installed to replace a gas-fired system. Pricing was on point. The system is virtually noise-free compared to that which was removed. Tim, the Owner was very easy to deal with on every level (no hard sell). Highly recommend."

"Fred is an amazing pro. Nobody was experienced enough to fix my pool heat pump. He did it in no time. He researched the system specifications to achieve a top repair. I am so lucky to have met him. Don’t waste your time calling any repairman who will charge you $200 just to look at your machine and charge you for repairs! Fred is nice and friendly. Call him, you will thank me later"

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