Houston HVAC Survival Guide: Preparing Your System Before Summer Hits
Every Houston homeowner should run through this checklist before May — once the heat arrives, HVAC companies are slammed and wait times get long.
Spring preparation checklist:
Outdoor unit (condenser):
- Clear all debris, leaves, and vegetation from around the unit
- Gently clean condenser fins with a garden hose (spray from inside out)
- Check that the unit is level on its pad
- Trim back any shrubs to maintain 2-foot clearance on all sides
Indoor unit (air handler):
- Replace air filter
- Check and clean condensate drain pan — pour 1 cup of white vinegar down the drain line
- Inspect refrigerant lines for insulation damage
- Make sure the access door is sealed completely
System testing:
- Set thermostat to COOL, drop to 70°F, and confirm the system produces cold air within 15 minutes
- Listen for any new noises — banging, squealing, or rattling that wasn't there last season
- Check every vent in the home — weak airflow in specific rooms can indicate duct issues
If anything seems off during this walkthrough, call Air Zone Plus before the summer rush hits. Scheduling maintenance in March or April means faster appointments, better pricing, and peace of mind heading into July and August. Call (346) 676-8752.
