I've used Air Repair twice (different unrelated issues - blown A/C capacitor and worn out furnace sensor), and both times they were prompt and resolved the issue for a reasonable price. The first time a bigger name national competitor wanted to replace the whole A/C system for thousands of dollars, and treated me rudely on the phone when I mentioned that it seemed like there were cheaper alternatives based on my research. Maybe replacing the whole system was inevitable eventually, but it wasn't the right time to do so for our budget, and Air Repair fixed the issue with a new capacitor. They also advised on ways to keep the system running efficiently, e.g., cleaning dust and debris from the compressor unit with a hose, and changing filters monthly.
