How We Helped an Addison Family Stay Cool

A homeowner near Addison Road called us on one of the hottest days of the year after her upstairs bedrooms had been uncomfortable for nearly a week. Our technician found a failed capacitor paired with low refrigerant — two separate issues compounding each other. He replaced the capacitor, corrected the charge, and tested the system thoroughly. By that evening the second floor was cooling again.

Frequently Asked Questions

How long does an AC repair typically take in Addison?
Most repairs are completed in one to three hours during a single visit. If a part needs to be ordered, we schedule a follow-up quickly and keep you informed on timing.
If your system is over 12 to 15 years old, needs repeated repairs, or cannot keep up on the hottest days, replacement may be more cost-effective. Our technicians give you an honest assessment of both options.
Yes. We service ductless mini-splits including refrigerant recharging, component repair, and diagnostic work. If your mini-split is not cooling properly, call us to schedule a visit.

A severely clogged filter restricts airflow enough to freeze the evaporator coil and shut down cooling. Replacing filters regularly is one of the easiest ways to prevent unnecessary service calls.

We recommend a professional tune-up once a year, ideally in spring before the cooling season begins. Preventive maintenance catches small problems early and keeps your system running efficiently all summer.
