Cary, NC · Serving the Triangle
A 21-point inspection built for NC's demanding climate — spring pollen, summer humidity, and everything in between. We clean, test, and tune your system so it's ready for the Triangle's next season before it arrives.
Our comprehensive inspection covers all mechanical, electrical, and safety components of your heating and cooling system from top to bottom. We check crucial connections, thermostat calibrations, and system safety switches to protect your home.
By finding and documenting worn parts early, we prevent sudden breakdowns when extreme weather arrives. This thorough review provides you with an accurate picture of your system's overall operational health.
Dirty filters restrict airflow and force your system to work harder, which spikes energy bills and stresses vital parts. We replace filters with the correct type and MERV rating for your system's design.
Installing fresh filters keeps your indoor air clean and reduces allergens throughout your living spaces. Regular changes protect your equipment from dust buildup and preserve strong, balanced airflow in every room.
Dirty evaporator and condenser coils significantly reduce efficiency by blocking proper heat transfer. We clean both coils to restore optimal cooling capacity and prevent your compressor from running excessively long cycles.
Clean coils allow the refrigerant to release and absorb heat easily, which directly lowers your monthly utility expenses. Protect your system from overheating with our safe, professional coil treatment.
We verify that your refrigerant charge sits strictly within manufacturer specifications. Our technicians check for potential leak patterns and can top off levels as needed to maintain maximum cooling performance.
Correct refrigerant levels are essential to prevent frozen coils, weak airflow, and eventual compressor failure. We ensure your system uses energy efficiently while keeping your home icy cold.
We test capacitors, contactors, fan motors, and control wiring for signs of wear, overheating, or failure. Identifying weakened components allows us to replace them before they cause an electrical shutdown.
Unchecked electrical issues can permanently damage expensive components like your compressor. Our detailed testing ensures safe, steady power delivery and reliable start-ups through every seasonal cycle.
Clogged condensate drains can cause sudden water backups, ceiling damage, and mold growth. We flush and clear your system's drain lines during every routine maintenance visit to keep things moving.
By removing algae and dust buildup, we protect your property from unexpected moisture overflow. Enjoy peace of mind knowing your system safely manages and removes humidity from your home.
Regular maintenance catches the failure points NC systems hit hardest — clogged drain lines in humid summers, worn capacitors before July, pollen-coated coils before spring’s peak.
A clean, well-tuned HVAC system runs 10–25% more efficiently — which adds up fast across Wake County's 6-month cooling season.
Properly maintained systems last 3–5 years longer than neglected ones — especially important given how hard NC's climate works air conditioning equipment.
Fresh filters, clean coils, and clear drain lines prevent oak and pine pollen from recirculating — and stop mold from forming in humid NC drain pans.
Most major HVAC brands require documented annual maintenance to honor equipment warranties. Air Secure provides official service records accepted by all major manufacturers.
