About CTS
About CTS Air Conditioning
A local Phoenix-area HVAC and plumbing contractor for AC repair, replacement, commercial rooftop work, maintenance, water heaters, and other plumbing.
Local HVAC Service
Local company, hands-on work
Certified Technical Services, known as CTS Air Conditioning, has served Phoenix-area homes and businesses since 2001. The company is locally owned, veteran-owned, family-owned, licensed, bonded, and insured.
You call, we look at the actual equipment, and we explain what we find. Sometimes the right answer is a straightforward repair. Sometimes replacement makes more sense. Either way, the recommendation should be clear.
Family Owned
The people behind the work
This is a local family business. We answer the phone, check your equipment, explain the problem, and recommend the repair or replacement that fits the situation.
Tony Aimonetti, owner
Tony owns CTS Air Conditioning and handles the business side of the company: customers, the website, service direction, and keeping the company focused on practical repairs when repairs make sense.
For Tony, family-owned means more than a phrase on a page. It means the company name is attached to real people, customer calls, and work done in the Phoenix area.
Leon, lead technician and partner
Leon is the lead technician and a partner in the business. He handles many of the service calls, repairs, diagnostics, rooftop units, installations, water heater jobs, and other plumbing work.
He checks the equipment before recommending a repair. That matters because one symptom can come from airflow, controls, wiring, refrigerant, drains, motors, or worn-out equipment.
Field Experience
Leon is the lead technician
Leon is a partner and the lead technician. He has handled much of the company’s field work for years.
HVAC problems can hide behind the first symptom. A bad capacitor, weak contactor, dirty coil, low airflow, drain problem, refrigerant issue, control problem, or failing motor can all feel like the same complaint from inside your house. Good service starts with checking your system and explaining what is actually happening.
