"Bob Jenson A/C and Heating provided an annual service for our air conditioner. Service was very competently and thoroughly performed by Carlos with assistance from Jack. They arrived right on time, as usual, and were very considerate and hard working. Carlos was a wealth of information and was able to answer all of my questions. Bob Jensen Heating and AC have been providing maintenance, service, and repairs for our units for many years, and I have always found them to be very competent and exceptionally pleasant/helpful to work with. I would highly recommend their Comfort Club Maintenance Plan. It is a good way to ensure regular annual maintenance for your furnace and air conditioner and a very cost effective way to get help and repair service when needed."

"Received estimate from Kade via email. He said that if I had any questions to call. Estimate was for $6056 with new furnace. I called office on 07/26/2019 (same day as original estimate) to see how much to replace 2nd unit and was told it was late in the day but someone would call back on Monday. I responded to email to make sure there was a record of my request since companies tend to get busy. On Monday I called again and was told that Kade wasn't in the office but the office person said that she thought someone was working on the price. She said I would get a call back. A week later, no call. I guess they don't need my $12,000. Estimate order number: 001085-1. They need to change their above description: Our mission is to provide the highest quality of service to all our customers."

"I'd like to take a moment to share with you my experience with Air Care Heating and Cooling who recently installed a new heating furnace replacing our original heater from 1976. After interviewing four reputable local companies in San Diego I chose aircraft based on excellent reviews on Google and Angie's list. Mr Michael Santana (Owner and founder) offered very affordable pricing compared to others not forsaking the quality of/ furnace unit, warranty and exemplary customer care /service. The installation process was flawless. Mr Santana's and staff demonstrated outstanding professional performance, effective communication to answer questions and concerns even adding extras like replacing events and the job completion in a timely manner making the whole process from beginning to end a truly"

"We recently had Same Day Heating and Air Conditioning come to our house to inspect our furnaces before turning the furnaces on during the cooler winter months and they discovered that both units had gas leaks. The system is 20 years old so it wasnâ t a complete surprise although we had hoped to put off replacing them for about 1-2 years. The technician/ inspector was knowledgeable, thorough and professional in showing us pictures of the worn, damaged furnaces (2). He explained the options for repairs and replacement as well as pricing considerations. In the end we decided to have them install 2 new furnaces and 2 new heat pumps to replace our old AC units. The installation was scheduled and completed within a short time frame and done with as little disruption to our home and family as possible. Efficient and neat in their work, I can happily recommend Same Day Heating and AC. I am very reassured knowing that my furnaces and heat pumps can effectively and safely heat and cool our home for our family. Peace of mind is priceless when it comes to protecting your family."

"Excellent work. Far surpassed expectations. Highly competent & professional from initial analysis of multiple problems and engineered a solution followed by a fast, efficient tear-out and installation by terrific crew to final clean-up. Excellent value. Job was professionally done the way the original installing HVAC contractor should have done years ago. Highly recommended."

"I obtained several quotes for replacing or repairing an old furnace and a/c condenser unit.  Each provider had a slightly different opinion on how much of the system should be replaced and what capacity unit should be used. Carini's prices were in line with other providers, but Kurt, who gave the estimate, seems the most knowledgable.  He did appropriate follow up after the install.  Would use them again. "

With the cleanouts snaked, and the blockage located, we can send the hydro jet through the sewer vent and flush out the blocked drain.

"I was really impressed with the service provided by Nadav and he is team. I have a thirty year old home that still had the original HVAC systems. One located in the attic and the other underneath the house. Neither of these installations was simple. The Sky Clean Air team quoted me two days to remove and install new systems. The install crew was really professional, courteous and hard working. The underneath the house install was especially difficult with a tight crawl space in a less than hospital environment. These guys were not a show up at 10 leave at 3 pm crew.......they worked long hours both days to ensure they met the promised schedule.They kept me informed any issues throughout the installation process so there were no surprises. At the end of two days we had two beautifully installed systems that now cool our 4000 sq ft house in a matter of an hour instead of the 4 or 5 the old system required. I feel that the pricing they gave me was very fair and at the end of the job I felt like I got more value than what I paid. I would certainly use them again in the future."

"Michael offered great advice on where to place our new tankless heater and his team did a great job executing. There were a few hiccups that came with replacing the old tank heater and working with the old plumbing of the home, but Jax Mechanical were able to solve any problems that popped up. Michael was also proactive in the initial discussion and found that our PRV needed replacing which was something we were glad he found before it led to any long term issues."

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