Highest-Rated Air Conditioning Service in Tucson AZ

Challenge

Homeowner scheduled routine spring AC service in April before summer heat arrived. System was 8 years old with no service history from previous owner. During our 23-point inspection, we discovered refrigerant levels 15% low, outdoor coil heavily clogged with cottonwood debris reducing airflow by 35%, blower motor capacitor testing at 32 microfarads (spec: 45 mfd) indicating imminent failure, and electrical connections showing minor corrosion. Left unaddressed, these issues would likely cause complete system failure during peak summer heat requiring emergency service and costly repairs.

Solution

Our NATE-certified technician performed comprehensive service including professional coil cleaning restoring full airflow, refrigerant leak detection and repair with proper recharge to factory specifications, capacitor replacement preventing imminent compressor damage, electrical connection cleaning and tightening, drain line flush, and thermostat calibration. We also identified and sealed duct leaks in the attic losing 18% of cooled air, maximizing system efficiency. Total service time: 3.5 hours including all diagnostics, repairs, and optimization.

Family of four scheduled spring AC tune-up for both their main 3-ton unit and 2-ton garage/bonus room unit in early March. The main system showed signs of short-cycling, running only 8-10 minutes per cycle instead of the optimal 15-20 minutes, while the garage unit wasn't cooling adequately during warm March afternoons. Previous service provider had performed only basic filter changes without comprehensive diagnostics. Our inspection revealed main unit's thermostat was mis-calibrated by 5 degrees causing excessive cycling, dirty evaporator coil restricting airflow 40%, and failing run capacitor. Garage unit had refrigerant leak in evaporator coil losing 2 pounds over winter, and crushed return duct reducing airflow by 30%.

Solution

Performed complete tune-up on both systems including evaporator coil chemical cleaning, run capacitor replacement on main unit, thermostat calibration and relocation away from afternoon sun exposure, refrigerant leak repair and recharge on garage unit, and duct repair restoring proper airflow. We also enrolled the family in our preventive maintenance plan providing bi-annual service, priority scheduling, and 15% discount on future repairs. Both systems tested at manufacturer specifications after service, with proper cycling, full airflow, and optimal cooling capacity restored.

Property manager for professional office complex with 12 individual office suites needed reliable AC service for three 5-ton commercial rooftop units serving the building. Previous service provider offered only reactive repairs when systems failed, resulting in three emergency breakdowns during summer 2023 disrupting tenant operations and generating complaints. Summer cooling costs had increased 35% over two years despite no changes in building use or occupancy. Manager sought proactive preventive maintenance program to improve reliability, reduce energy costs, and maintain tenant satisfaction in competitive office rental market.

Solution

Implemented comprehensive commercial AC maintenance program with quarterly service visits scheduled in March, June, September, and December. March spring service revealed multiple issues: Unit 1 had failed economizer damper stuck open wasting energy, Unit 2 showed 20% low refrigerant from slow leak, Unit 3 had biological growth in drain pan and clogged filters. We performed complete service on all three units including coil cleaning, filter replacement with high-efficiency commercial filters, refrigerant leak repair and recharge, economizer repair and calibration, belt tension adjustment, bearing lubrication, and control system optimization. Established ongoing service agreement with priority response, discounted rates, and detailed service documentation for property records.
