I've used Alpha Heating & Air Conditioning twice now. Shaq came out on the first visit and Steve on the second. Thought I was low on coolant after inspection it was found the capacitor was faulty in which they replaced. The coolant was fine and they did not try to upcharge me or sell me something I didn't need. Pros: - Easy to schedule an appt (at my home on time)- Honest and friendly- Prices reasonableCons:- None I would highly recommend these guys to family, neighbors, and friends.
