General HVAC Questions
How often should I replace my HVAC filters?
For most homes, filters should be replaced every 1–3 months depending on usage, allergies, pets, and the type of filter used.

Most systems last 10–15 years with proper maintenance. Older units may still function but typically lose efficiency and reliability.

The right size depends on factors like square footage, insulation, layout, and local climate. We perform a load calculation to recommend the most efficient system for your home.
Do you install smart thermostats?

Heating & Cooling Efficiency & Safety
How can I reduce my energy bills in extreme Texas weather?
Regular maintenance, sealing ductwork, using programmable thermostats, and upgrading to a high-efficiency system can make a big difference in your energy usage.
What’s included in a maintenance tune-up?
Our HVAC tune-up includes checking refrigerant levels, inspecting and cleaning coils, testing electrical components, calibrating the thermostat, and more. It’s a full system check-up.
Why is my AC blowing warm air?
This could be caused by low refrigerant, a dirty coil, or a malfunctioning compressor. We’ll diagnose the issue quickly and recommend the best fix.
Is it safe to run my heater if it smells like something is burning?
A slight burning smell the first time you turn on the heat is normal (dust burning off). But if the smell is strong or persists, turn off the system and call us right away.
