"I used their website feature to request a tech for residential A/C repair for the following day. But I received a phone call from Cytech a couple of hours later asking if I wanted service earlier as they had a tech available at that time, which worked out even better for me. The service call and repair was completed in 45 minutes after tech arrived in a efficient and professional manner. Tech even went above and beyond the repair and fixed up a couple of minor issues without charging me anything additional. I'll will be calling them again in the future should I need HVAC services!"

"I was very satisfied with the service. The price was negotiable and fair. Jaime and the two young men helping him were very courteous and arrived to work on time. All components of the A/C were cleaned very well. I really appreciated the way they identified the repair needed to stop air escaping from the air handling unit and sealed with silver HVAC tape. I highly recommend Beto's Clean Ducts."

Heating and Air Conditioning FAQs, answered by experts

Capacitors are the most frequent part of an HVAC system to experience failure. These components are crucial for starting the motors that power the fans and compressor, but over time, they may become worn or fail due to electrical surges or regular wear and tear. When capacitors malfunction, HVAC systems may experience decreased heating or cooling efficiency, or even total system failure. Replacement or maintenance of capacitors is a common requirement for the optimal functioning of HVAC systems.

AC leaks are common, and an HVAC pro can usually fix them. You may be able to resolve some leaks on your own, but a professional HVAC technician should handle most AC leak repair. If left ignored, an AC leak could cause serious damage to your system or leave you with expensive water damage, usually leading to more costly repairs or replacements.

A damper motor can last up to 15 years, but it can wear out more quickly than that if you run your HVAC unit a lot. So you might expect a longer life in a colder climate than if you live in a warmer climate.

Fixing a leak in an AC unit costs $200 to $1,600, depending on the type of leak and any related damage. But depending on the age and condition of your AC, it might make more sense to replace the AC unit instead of repairing it. If your AC is only a few years old and relatively problem-free, then repairing it is the right call. But if it’s nearing a decade old and has other issues, consider replacing it.

The cost to repair an air conditioner averages around $350 to $450, but the price can range from $100 to over $3,000. The final cost depends on the type of air conditioner, the extent of the damage, and the specific parts that need replacement. For example, repairing a window AC unit typically costs between $100 and $250, while central air conditioner repairs can range from $300 to $3,000. A simple fix like replacing a dirty filter might only cost $10 to $50, but a major issue like a broken compressor could cost around $2,000 or more, potentially making it more cost-effective to replace the entire system. Due to the need for specialty tools and handling of refrigerants, repairs more complex than changing a filter are best left to a professional.
