What to Expect During a Summer HVAC Tune-Up in Georgetown and Round Rock, TX

If you live in Georgetown or Round Rock, you know that Central Texas summers are no joke. With temperatures soaring into the triple digits, your air conditioning system works overtime to keep your home cool and comfortable.

That’s why a summer HVAC tune-up isn’t just a nice-to-have — it’s essential. At McCullough Heating & Air Conditioning, we help homeowners across Georgetown, Round Rock, and the surrounding areas prepare for the heat with expert AC maintenance that saves money, prevents breakdowns, and keeps your system running at peak performance.

Here’s what you can expect when you schedule a summer HVAC tune-up with our trusted, family-owned team.

1. Full-System Inspection

Our licensed HVAC technicians will start by inspecting the entire cooling system, including:

• Air conditioner or heat pump
  
• Thermostat calibration
  
• Electrical connections
  
• Safety controls
  
• Refrigerant levels
  
• Drain lines and condensate pans
  

We check for any signs of wear, potential failures, or safety concerns that could become costly problems during a Georgetown or Round Rock heatwave.

2. Coil & Component Cleaning

Your system runs more efficiently — and uses less energy — when it’s clean. During your tune-up, we’ll:

• Clean or replace air filters
  
• Remove dirt and debris from the outdoor condenser coil
  
• Inspect and clean the evaporator coil
  
• Clean the blower components and inspect the fan motor
  

Dust, pollen, and even local Round Rock oak or cedar allergens can clog your system. A clean unit means better airflow, fewer breakdowns, and lower energy bills.

3. Performance Testing

After inspecting and cleaning your system, we’ll test it under real operating conditions:

• Measure airflow and temperature differentials
  
• Test the thermostat for accuracy
  
• Ensure refrigerant levels are within the manufacturer’s specs
  
• Run diagnostics to spot inefficiencies or inconsistencies
  

This ensures your AC is truly ready for the hottest days in Georgetown and Round Rock — not just working, but working efficiently.

4. Energy-Saving Recommendations

At McCullough, we’re not here to upsell — we’re here to help. After your tune-up, we’ll let you know if there are cost-saving opportunities like:

• Smart thermostat upgrades
  
• Duct sealing or insulation improvements
  
• High-efficiency system recommendations (if needed)
  

Our goal is to help homeowners in Georgetown and Round Rock get the most comfort for the lowest cost, especially during long, hot Texas summers.
