What is Semi-Annual HVAC Maintenance?
Semi-annual HVAC maintenance means two scheduled visits per year: a spring air-conditioning tune-up before the summer heat and a fall check of the heating system. Each visit includes cleaning, testing and adjusting the equipment so it runs efficiently and problems are caught before they become breakdowns.
What’s included
- Spring cooling tune-up and fall heating safety check
- Refrigerant pressure and temperature-split testing
- Outdoor condenser coil rinse and debris removal
- Evaporator coil and drain-line inspection and flush
- Capacitor, contactor and electrical connection testing
- Blower motor and fan inspection
- Thermostat calibration and operation check
- Air filter check / replacement
- Written report with recommendations and photos

Frequently asked questions
Why do I need HVAC maintenance twice a year?
In the Rio Grande Valley the air conditioner runs most of the year. A spring tune-up prepares the system for peak heat and a fall check covers the heating side. Twice-a-year maintenance improves efficiency, prevents breakdowns, extends equipment life and is often required to keep manufacturer warranties valid.
What is included in an AC tune-up?
We clean the outdoor coil, flush the drain line, test refrigerant pressures and temperature split, check capacitors, contactors and electrical connections, inspect the blower, calibrate the thermostat and check the filter. You receive a written report of the system condition.
When should I replace my AC instead of repairing it?
Consider replacement if the system is 12–15+ years old, uses R-22 refrigerant, needs frequent or expensive repairs, or can no longer keep your home cool. A new, correctly sized high-efficiency system can noticeably lower your energy bills.
What size AC unit does my home need?
Proper size depends on square footage, insulation, windows, sun exposure and ceiling height — not just square footage alone. We perform a load calculation during the in-home evaluation so the new system is sized correctly.
How often should air ducts be cleaned?
Most homes benefit from duct cleaning every 3–5 years, or sooner after a remodel, construction work, a pest problem, or if family members have allergies.
