I recently noticed my electric bill started creeping up starting June 2021, first 200, 300, 400 kw's to finally Jan2022 1500 kw's over the previous year usage. I called CPL to check my meter which they said was operating correctly. CPL said that much overage almost had to be an AC problem. On 4/27 I called for Jorge at Hess Air. He has worked with me since I bought my house in 2015. He supervised the moving of AC lines when I removed a wall.
He has always taken extra steps and time to explain my system and what needed repair. My system checked out so then he moved outside to check the amps of each breaker. When he got to the garage he said this is the problem area and recommended turning off the window unit. I expectantly waited for a month to get my new electric bill. April usage was 2306 kw, I turned of window unit 4/27. May usage was 1345, almost half of the previous month. Then Jorge gave me some maintenance tips for the window unit to possible reduce its electric usage if I turn it back on. I couldn't be happier and more satisfied with Jorge and Hess Air.

I think you need to shop around. Prices are rather steep for cleaning a system. No doubt they'll find more things wrong with your unit. Change your filters often and take a peek under to look at your coils to see if cleaning is needed. Hose off the dirt on the outside fan and just those little things will save you money both on repairs and electricity.

Critical: Professionalism, Value $300 dollars to replace a blown capacitor? Have these people lost their minds? Tech got real surly, and so did I. Paid service call & sent him packing.

Everything was great until it came time to pay. After he finished, the tech raised his estimate by $19 with no explanation. I had asked him about the price and was assured that that was going to be the price with no additional charges. I did not receive an itemized bill or receipt. The service was great but I don't appreciate price change.
