Customer Reviews
Technician arrived within 2 hours on a 95-degree afternoon. Diagnosed a refrigerant leak, replaced the valve, and tested everything. System worked perfectly again.
Honest pricing—they quoted $450, finished early, and charged exactly that amount. No surprise fees. Booked them for our spring maintenance too.
AC stopped cooling in July. Called at 6 PM on a Friday, got service the next morning. Professional crew fixed a failed capacitor fast.
Been using KSA for 3 years now. Annual maintenance costs less than dealing with emergency breakdowns. Our AC lasts longer with their preventive care.
Technician explained what was wrong, why it mattered, and what the fix would cost before starting work. Felt completely comfortable with the decision.
Replaced our old unit's compressor instead of selling us a new system. Saved us thousands. That's the kind of integrity you want from a contractor.
Called for emergency service during a heat wave. They showed up in 90 minutes and had us cooling again by evening. Professional and efficient.
Three service visits over two years—all covered under their maintenance agreement. Every visit includes filter changes and system checks. Worth every penny.
Our commercial building's AC failed during business hours. Response time was under an hour, and they worked through the afternoon to get us back online.
Technician found a minor duct leak that nobody else caught. Sealing it improved cooling and dropped our energy bills by 12%.
Friendly crew, clean work space, and thorough inspection. They showed me the dirty coil with photos so I understood why cleaning helped.
Service agreement includes priority scheduling. When our AC acted up mid-summer, we got a same-day appointment instead of a 5-day wait.
Fixed a refrigerant leak and rebuilt the valve assembly. Total time on site was 3 hours. System runs as if it were brand new.
Called multiple companies for quotes. KSA was middle-priced but best-reviewed. Decision paid off—excellent work and fair billing.
They replaced the blower motor and fixed an electrical issue we didn't even know about. Thorough inspection caught everything.
Emergency call at 11 PM when our bedroom AC failed. Dispatch said a tech could be here by midnight. Got cold again before bed.
Seasonal maintenance keeps our system running at peak efficiency. Last summer's cooling bills dropped compared to previous years.
Technician spent time explaining the difference between our system's age and condition. Repairs made sense—replacement could wait another 3-4 years.
