Best Heating & Air Conditioning Company in El Cajon

Semper Air Heating and Air Conditioning

El Cajon is a city just east of downtown San Diego in a valley surrounded by beautiful mountains. El Cajon is a diverse town with family restaurants representing different cultures. Residents and visitors enjoy the wide variety of ethnic cuisine right around the corner any day of the week. Along with enjoying easy access to the beaches and desert that is a plus of El Cajon, residents and visitors are attracted to the hiking and walking trails on El Cajon Mountain, called El Capitan. It is known for having the most challenging hiking trails in San Diego.

The City of El Cajon is on the rise with the potential to be a gorgeous city, with improvements planned to create a better quality of life for the people who live there.

The stated goals of this initiative are to reduce pollution, improve community resilience, better manage natural resources, create community-wide change, and reduce greenhouse gas emissions.

Plans for incorporating smart city technology to improve infrastructure, efficiency, convenience and quality of life

Planned improvements are to create a “pedestrian-friendly” retail village, with wider sidewalks and pedestrian crossings, planted parkways, trees, benches, new streetlights, and drain and waste systems.


El Cajon is on the road to improve conditions for the people. With all the focus on upgrading the city, homeowners may not realize the opportunity to create better living conditions in their own homes. Inefficient heating and air conditioning uses more electricity than anything else in your home and represents nearly half of your utility bill. You can save money and improve the comfort in your own home by upgrading to a new energy-efficient HVAC.

Repair or Replace Your HVAC?

If your HVAC is older or in disrepair, it might seem less costly to repair it and move on. But the older HVACS are inefficient and use up even more of your energy, so the cost reflected in your electric bill is much higher than it would be with new energy-efficient technology. The older HVACs use toxic coolants and burn fossil fuel for heating. The combustion from the furnacecreates conditions for carbon monoxide poisoning, which has no odor and is undetectable until it’s too late.

Semper Air can evaluate your HVAC system to see if it needs replacement. But replacing the whole unit is not only cost-effective, but it is also cleaner and safer. We offer replacement of HVAC units in El Cajon that come with lifetime warranties. Whether you want central air to utilize your home’s duct system or prefer a ductless mini-split that works on heat pump technology, we have you covered with many energy-efficient equipment options.

Signs That You May Need To Replace Your Air Conditioner

Solar Power in El Cajon

El Cajon has costly power bills. Many homeowners have adopted solar panels as their energy source and are saving big on their electricity bills, running AC all summer long at no extra cost. And electricity demand is increasing, not decreasing as we acquire more smart devices, as you can see by El Cajon 2.0 plans for the future. You can power your new HVAC and everything in your house with solar panels. You can even heat your pool. Solar gives you more freedom to do more with your electricity without costing any more.

Semper Air will install your new HVAC and Solar panels together for much cleaner and less costly energy use. Or, if you already have a new HVAC, we can add solar panels. We offer the very best air conditioners, furnaces, ductless mini splits, and more. Our military-grade products are from the most reputable companies in the business. We will have your HVAC working seamlessly with your Solar Panels. Solar power is a very smart move for homeowners in El Cajon.

Comfortable, Safe Indoor Air

Biological contaminants such as mold, spores, dust mites, and other tiny organisms reside in the home and infiltrate the air in your home. These contaminants are the cause of many respiratory diseases and even viruses. They circulate through your inefficient HVAC and duct system into your living spaces and are in the air you breathe. Indoor air quality is now more important than ever.

The new energy-efficient HVACs control the temperature and comfort of your home. They have powerful filtering and cleaning capabilities that older models don’t have. CDC considers effective air conditioning to be a partner in reducing the spread of the virus that causes Covid19. If you follow all the other safe practices, this can be another layer of protection for your family.
