Customer Reviews

Gave Us a Very Competitive Price!

Time to replace our 32 year old Carrier hvac so I called an authorized dealer--Zodiac. Saul came to our house and gave us a very competitive price! Days later, Hugo and the team showed up on time and they were polite and respectful of our property. We were very impressed with their professionalism, courtesy and work ethic! The new system ( ac, furnace, coil, ducting, thermostat) is working fine…

Furnace/Air Conditioner Tune Ups & Preventative Maintenance, Simi Valley, CA

No matter how new or old your heating and air conditioning equipment is, preventative maintenance is always recommended. For newer systems, it is not only required by most manufacturer warranties, but also critical to keep it running smoothly, consistently, and energy efficiently. For older systems, preventative maintenance prepares your system for Simi Valley's hottest and coldest months of the year, when you need to ensure that your equipment is clean, safe, and ready to handle a dramatic increase in usage.

At Zodiac Heating & Air Conditioning, we offer comprehensive furnace and air conditioner tune-ups in Simi Valley at very affordable prices. Our AC tune-up includes a thorough cleaning of the condenser and all coils, replenishing refrigerant, checking all electrical connections, lubricating moving parts, changing or cleaning the filter, and verifying that the equipment is running within the parameters specified by the manufacturers. Our furnace tune-up includes checking the gas lines, pilot light, belts, blowers, and fan, checking the ignition system and safety control, cleaning and lubricating any moving components, changing the filter, and recalibrating the system as needed. If there are any signs of problems that could potentially lead to costly repairs or unexpected breakdowns in the future, we will notify you and review your most cost-effective options. Tune-ups can be scheduled at any time of the year, but are best to schedule in the spring for air conditioners and in the fall for furnaces. If you'd like to ensure you don't fall behind on your furnace and air conditioner tune-ups, we recommend signing up for our Maintenance Agreement program. As a Maintenance Agreement member, you can count on us reaching out to you each spring and fall to schedule your tune-up. Additionally, we'll give you priority service if you ever need repairs and discount repair services by 15%. Call today to learn more.
