We prioritize safety checks and efficiency optimization while providing transparent cost estimates before performing any repair work on residential or commercial heating systems.

Financing options are available for qualifying customers seeking to upgrade aging systems that show decreased performance or increased energy consumption patterns.

Questions

How do I know when to replace my HVAC system?

Consider replacement if energy bills increase 15%+ annually, system noises become excessive, repairs become frequent, or equipment exceeds 15-20 year lifespan. Our technicians provide free evaluations to determine cost-effectiveness of repairs versus replacement.

Do you offer financing options for new installations?

Yes, we provide financing programs for qualifying HVAC equipment purchases. Contact our office for current promotions and to discuss payment plans that make system upgrades more affordable while maintaining your property's comfort standards.

What size HVAC system do I need?

Proper sizing requires calculating square footage, insulation quality, and climate factors. Our technicians perform detailed load calculations to recommend equipment that balances efficiency with adequate heating/cooling capacity for your specific San Diego property.

How much energy savings can I expect with new equipment?

Modern systems typically reduce energy consumption by 15-20% compared to decade-old units. Actual savings depend on insulation quality, window efficiency, and usage patterns. We help select optimal SEER ratings and programmable thermostat integration to maximize efficiency.

How often should I schedule HVAC maintenance?

We recommend biannual maintenance (spring for AC, fall for heating) for San Diego's mild climate. Properties using systems more frequently may benefit from quarterly filter changes and inspections to maintain efficiency and prevent unexpected breakdowns.

What maintenance tasks should homeowners perform?

Replace air filters every 2-3 months during active use periods. Keep outdoor units clear of debris and ensure unobstructed airflow around indoor equipment. Schedule professional maintenance annually to address technical components and system calibration needs.

Aairco were very professional and honest. My furnace (after 25 years) went out. Kris came out and gave an honest estimate that the main board had failed. The initial quote for the board was around 900. Kris gave me a quote for a new furnace at a VERY reasonable price. He was out the next day to install. Kris and his company are extremely reliable, honest, and trustworthily. I would highly recommend them to anyone who needs assistance.

Worst company ever experienced.The practices they did wasn't good and insufficient systems. Didn't have the correct parts but they hacked it to somehow make it work. HACKS!!!! For sure will need to be services sooner then later. Owner n was good and did his best but supervisors and leads half assed the job. Didn't care how just make it work. New company definitely will go thru some growing pains

I contacted this company because we needed a new furnace, but then decided to also install central air in our home. I was really impressed with this company. Kris Zimmer (the owner) gave me all the information I needed to decide exactly what type of AC option to go with. He actually came out to survey the house as well. His employees were very professional and wore masks the entire time they were in our home. Phil, Jared, and Isaac did a great job installing everything and showing us how to work the new thermostat. They were all very fast, efficient, and neat. They finished within 2 days. I was

I called the company to service my air conditioning and Kristen was able to get a tech out quickly. Jeff serviced my air conditioner/heater, was extremely knowledgeable and very friendly I will use this company from now on. No sales pitch to upgrade my old unit. It is refreshing when a company doesnt pressure you for unnecessary purchases. Thanks Jeff and thank you Aairco!

I've used these guys twice in the last three years, and both times I was super impressed with the service.

They're a lot farther away from where we live, but I had a friend that highly recommended them. After the service we got, I know why. We had a problem with the heating in our home, and they quickly fixed the problem and we're happy with the price. For some reason, after they finished, I decided to call another place just to see if they would've beaten that price. The quote they gave us was a lot more, and before I could say anymore, that company said they wouldn&apos
