When summer temperatures hit triple digits in Texas, your A/C works overtime—and so does your energy bill. But staying cool shouldn’t cost a fortune.

At Tarrant Mechanical, we specialize in helping DFW homeowners and business owners stay comfortable without overspending on energy. In this guide, we’ll show you how to lower your cooling costs this summer through smart HVAC tips, maintenance tricks, and energy-efficient upgrades.

1. Schedule a Seasonal HVAC Tune-Up

Regular maintenance is one of the best ways to reduce cooling costs.

A professional tune-up:

  • Improves system efficiency
  • Fixes minor issues before they become major repairs
  • Ensures proper refrigerant levels and airflow

At Tarrant Mechanical, our seasonal HVAC maintenance plans help your system run cooler and cleaner, saving you money all summer long.

2. Upgrade to a Smart Thermostat

Smart thermostats are one of the easiest ways to lower energy bills.

Benefits include:

  • Custom scheduling
  • Auto-adjust when no one’s home
  • Remote access via smartphone
  • Learning your cooling habits for optimal performance

Over time, a smart thermostat can cut cooling costs by 10% or more—especially in high-usage months like July and August.

3. Replace Dirty Air Filters

A clogged or dirty filter makes your system work harder, increasing both wear and your electricity usage.

Tip:
Replace your air filter every 30–60 days during peak usage periods to maintain efficient airflow.

This small task makes a big impact on reducing cooling costs and avoiding unnecessary repairs.

4. Seal Leaks Around Windows and Doors

If cool air escapes through poorly sealed windows or door gaps, your HVAC system has to work overtime.

To fix this:

  • Install weather stripping around doors
  • Use caulk to seal window gaps
  • Consider blackout curtains or window film for added insulation

These minor fixes prevent air loss and heat intrusion, directly lowering your cooling costs.

5. Use Ceiling Fans the Right Way

Fans don’t cool the air—they move it. But they can help reduce your A/C usage when used strategically.

Make sure your ceiling fan:

  • Spins counterclockwise in summer to push cool air down
  • Is turned off in unoccupied rooms to save energy

When used properly, fans allow you to raise your thermostat setting by up to 4°F without feeling warmer.

6. Avoid Heat Buildup Indoors

Appliances and lighting add heat to your space. Try to:

  • Cook outdoors when possible
  • Use the microwave instead of the oven
  • Run heat-producing appliances (washer, dryer) at night
  • Replace incandescent bulbs with LEDs

These small habits reduce internal heat, making it easier for your HVAC system to maintain a comfortable temperature.

7. Consider an HVAC System Upgrade

If your A/C is 10–15 years old, it might be costing you more than it should.

Older units:

  • Use more electricity
  • Cool less effectively
  • Break down more often

New systems from Tarrant Mechanical are ENERGY STAR® certified, properly sized for your home, and equipped with modern controls to maximize cooling with minimal energy.

8. Shade Your Outdoor Condenser Unit

Placing your condenser in direct sunlight can reduce its efficiency. Instead:

  • Provide shade with shrubs (but allow airflow)
  • Build a simple cover with slats
  • Avoid enclosing it fully or blocking ventilation

A shaded condenser can improve efficiency by up to 10%, helping your system stay cool without overheating.

9. Use a Zoning System

If you’re cooling your entire home when only one room is being used, you’re wasting energy.

A zoning system lets you:

  • Cool only the rooms you’re using
  • Set different temps for different zones
  • Save significantly on your energy bill

Ask Tarrant Mechanical about installing custom zoning solutions for your home or office.

10. Insulate Your Attic and Ductwork

Poor insulation allows cool air to escape before it reaches your living spaces. By insulating your attic and sealing your ductwork, you’ll:

  • Keep cool air where it belongs
  • Reduce load on your HVAC system
  • Improve comfort year-round

Our team offers full inspections and insulation upgrades designed for Texas heat and DFW homes.
