In Houston and Katy, TX, HVAC systems work harder than in most parts of the country. Long cooling seasons, high humidity, and frequent thermostat adjustments place constant strain on heating and air conditioning systems.
Routine HVAC maintenance is not optional in Southeast Texas — it’s essential for preventing breakdowns, lowering energy costs, and extending equipment lifespan.
This guide covers everything homeowners need to know about maintaining their HVAC systems year-round.
Why HVAC Maintenance Is Critical in Houston & Katy
Homes in the Houston area face:
-
Extended summer heat
-
High indoor humidity
-
Heavy AC usage

How Often Should HVAC Systems Be Serviced?
In Texas climates, HVAC systems should be serviced twice per year:
Spring – Prepare for cooling season
Fall – Prepare for heating season
