AC Won’t Turn On or Off

Controllers that don’t trigger your cooling system or won’t stop running indicate electrical failures requiring replacement.

Frequent Temperature Swings

Rooms that shift between too cold and too warm signal calibration problems or failing internal components.

Frequently Asked Questions

How long does replacement take?

Most installations are completed in 1-2 hours. Simple replacements take less time, while first-time smart installations with C-wire additions may take slightly longer.

Will a new controller work with my old AC?

Almost always, yes. Modern units are compatible with most HVAC systems. We verify compatibility during our assessment. If your system lacks a C-wire for smart models, we can usually add one.

What’s the difference between programmable and smart models?

Programmable units let you set schedules manually. Smart versions connect to WiFi, learn your habits, can be controlled remotely via smartphone, and include energy-saving features that adjust automatically.

How much money will I actually save?

According to EPA Energy Star data, properly programmed temperature controls save an average of $180 annually on heating and cooling costs. Savings depend on your usage patterns, home size, and how consistently you use scheduling features.

Which brand should I choose?

Popular options include Nest (learns your schedule), Ecobee (includes room sensors), Honeywell Home (reliable and user-friendly), and Emerson Sensi (budget-friendly). We’ll recommend the best fit based on your priorities.
