"OUTSTANDING: I have preventive maintenance twice every year. Once to check all A/C equipment and once to check all Heating equipment. This past week technician Jeremy Zavala conducted the preventive maintenance on the Heating system. I was scheduled for the window of noon-3:00PM. Jeremy drove up at noon sharp! Jensen's techs have always arrived on the front end of the promised window. Jeremy was in a clean uniform; wore shoe covers so as not to track anything into my home; introduced himself; friendly and smiling; and went directly to work. He serviced the equipment as well as the thermostat then went over a list of everything addressed. Jeremy is a perfect example and representative of the things I personally want and Jensen A/C & Heating always provides: - Outstanding customer service - Well trained, knowledgeable service technicians - Prompt - Efficient - Respectful of my home: Always leaves the work area neat and clean - Trust-worthy - Personable - If a part needs replacement no need to special order - it's in the van - Jensen's Office & Administrative personnel also demonstrate the qualities noted above. - Always fair cost and excellent value And unlike many of the better known San Diego HVAC companies, Jensen has never made a sales pitch at the completion of a preventive maintenance service call. Since having Jensen as my only preferred HVAC provider my A/C and Heating has been 100% reliable."

Hydro jet uses water at 4,000psi to clean the inside of the mainline drain which connects all the home's drains to the city's sewer system.
Using a snake we can go through the cleanouts on the side of the house.
With the cleanouts snaked, and the blockage located, we can send the hydro jet through the sewer vent and flush out the blocked drain.

"My 40-year-old central A/C died on a really hot Wednesday. On Thursday, Airmaxx came out and verified it needed replacing. They also verified my suspicion that the old unit was undersized for my house. By 3:30 Saturday afternoon I had a complete new heating and A/C system installed and working. I was really impressed with their speed and efficiency."

"Did a great job...it was a very long day from start to finish however. They did a great job of keeping everything as clean as they could since our attic access was in the master closet! Yikes! Really made a difference and our house stayed much cooler with the fan and new insulation!"

Heating and Air Conditioning FAQs, answered by experts

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

The cost to add Freon to an AC ranges from $100 to $350. It can increase up to $600 for large AC units requiring much more coolant. The cost also depends on how much refrigerant your unit needs. If only a small amount of Freon leaked out, your cost would be on the lower side. A complete replacement of all the required refrigerant can get expensive.

The compressor is the heart of your AC system and is one of the most important parts required to keep it functioning properly. If your AC unit is making a popping, banging, clanging, clicking, or screeching sound, it could point to a problem with the compressor. If the unit is physically vibrating, that can also be an indication that your AC compressor is going bad.

Winterizing can still help you save money on energy costs and help prepare your AC for its work next year when you turn it back on. We suggest planning for at least some maintenance, even if winters are mild in your area.

Dry mode positively impacts indoor air quality by reducing excess moisture, which stops the growth of mold and mildew. By maintaining optimal humidity levels, dry mode creates a less hospitable environment for allergens and airborne pathogens, improving overall air quality. However, it's essential to ensure proper ventilation to prevent stale air accumulation.
