What each guide covers
Deciding whether to fix an aging air conditioner
The repair or replace guide walks through system age, which failures are worth fixing, R-22 refrigerant and a simple rule of thumb for the math. It's the one to read when a technician has just told you a big repair is needed on a system that's more than a decade old.
Comparing heat pumps and gas furnaces for mild winters
Our heat pump vs. gas furnace guide explains how each system heats, why heat pumps suit the valley's short heating season, when gas still makes sense and how dual-fuel systems work. Read it before replacing a furnace or switching an all-electric home's heating setup.
Filter schedules for dusty desert homes
The AC filter guide covers how often to check and change filters here, picking the right size and rating, the signs a filter is overdue and the washable filters in ductless heads. It's the quickest of the three to act on, and it can prevent a frozen coil.
Where to go next for service details
If a guide raises a question about your own system, the service pages go deeper. Start with AC repair for a system that's acting up, heating repair for winter problems, or the full services list to see everything from drains to water heaters.
