How to Prepare Your HVAC System for a Texas Summer

When the Texas heat hits, it hits hard. And if your HVAC system isn’t ready, you could be left sweating—and facing a costly emergency repair.

At Tarrant Mechanical, we help homeowners and businesses in DFW get ahead of the summer surge with professional HVAC prep services. Here’s your go-to guide to making sure your cooling system can handle everything a Texas summer throws at it.

1. Schedule a Pre-Summer HVAC Inspection

A professional inspection is the most important step you can take. We’ll evaluate:

• System performance
• Refrigerant levels
• Electrical connections
• Condenser and evaporator coils
• Thermostat calibration

Pro tip: Book early in the season before HVAC technicians are fully booked. Spring is the sweet spot for summer prep.

2. Replace or Clean Your Air Filters

Clogged air filters restrict airflow and force your system to work harder—raising your energy bills and increasing wear and tear.

Change your filter:

• Every 1–3 months in summer
• More frequently if you have pets or allergies

Clean filters = better airflow and cooler air faster.

3. Clean Around the Outdoor Unit

Your HVAC condenser unit needs space to breathe. Before summer:

• Trim back grass, shrubs, or debris around the unit
• Clear out leaves and twigs
• Gently hose off any dirt buildup

A clean outdoor unit = improved heat release and efficiency.

4. Test Your Thermostat

Now’s the time to verify your thermostat is accurate and responsive. Consider:

• Installing a smart thermostat for better control
• Programming temperature changes for day and night
• Setting your A/C to 76–78°F when home, 85°F when away

Smart temperature settings = energy savings all summer long.

5. Seal Air Leaks Around the Home

You could lose up to 30% of your cool air through leaks in:

• Windows and doors
• Attic and crawl spaces
• Ductwork

Use caulk or weatherstripping to seal gaps and keep your cool air in. Tarrant Mechanical also offers duct inspections to stop hidden leaks from draining your energy.

6. Check for Unusual Noises or Odors

Turn on your A/C and listen for:

• Rattling, squealing, or banging
• Musty smells or burning odors
• Poor airflow from vents

If anything seems off, it’s time to schedule a repair before the summer rush. These could be signs of worn parts, blocked drains, or dirty coils.

7. Upgrade Your HVAC System (If Needed)

If your system is:

• Over 12 years old
• Needs frequent repairs
• Struggles to keep you cool

…it may be time for a replacement. Upgrading to a high-efficiency system can reduce your energy use by 20–30%—and keep you comfortable during record-setting heat.
