Questions

When should I service my AC or heating in Dennison?

Book the AC tune-up in spring and the heating check in fall, before the first real heat or cold — repair slots fill fast in a heat wave.

How long do AC units and furnaces last?

Central AC units usually last 12–15 years and furnaces 15–20; past that, a repair often costs more than it saves.

Should I repair or replace my system in Dennison?

If the system is over 12–15 years old or needs a major part (compressor, heat exchanger), ask for both prices — the pro sends them on Homeshi so you can compare.
