Excellent service, as always!

Once again, Mike of Haas and Sons has provided top-notch expertise re: the wiring in our 1936 home in a historic district. Mike sorted out some old weirdness, made it safe and compliant, and upgraded our bathroom light and fan to a more powerful model. It wasn't the first -- and won't be the last -- time we reach out to them for help!

Diagnosed and Fixed

Nick figured out immediately what the problem was with the connection to the air conditioner and fixed it immediately. He saved us from sweltering under the summer heat.

The 2nd floor bedroom circuit tripped turning off window A/C unit in child’s room. I found that this circuit also controlled room underneath bedroom and lights in the basement corner. The A/C unit is 1000W and is on a 15 amp breaker. Circuit breakers are all new Cutler Hammer CH breakers. I found that the circuit is slightly over loaded. This size of equipment should have a dedicated circuit if other devices (ceiling fans, computers) want to be ran at the same time.
