Great Electrical Service

Experienced an electrical outage this morning. When it returned only had prower in half of the house. After being informed by another company that they would not be able to respond for four days, I contacted Haas and Sons who has performed work for us in the past. Michael arrived early, identified the issue and corrected it with outstanding results. Great work and thanks!

Glad I found them

Can not say enough great things about this company and Alex. They were able to schedule me right away. Alex knew what he was doing. Offered a couple of different options and prices for each and explained everything in depth. . Alex was great and really laid back, easy to talk to. Would recommend to anyone.

Choosing Haas and Sons is the best decision you will ever make!

I had a lot of behind the wall issues. After trying 2 contractors I knew it was time for a certified electrician. Each contractor left a trail of loose wiring and piggyback wiring that didn’t look correct to me. Which is saying a lot, as I do not do anything electrical. I contacted several electrical companies and I decided on Haas and Sons. Best decision ever! Quick response and explained how their service works. What to expect when the service technician arrives. Was even understanding about my concerns from prior contractors and I had an appointment within days. Alex the service tech was very professional and explained everything to me, in a way I could understand. Cleaned up after himself, which is a plus and before he left made sure I was satisfied with his service. I can now go to sleep tonight and not worry about what light or outlet is going to give out next. I highly recommend Haas and Sons to my family and friends.

Chandelier Installation

We had a chandelier to be installed in the foyer with a 20 foot ceiling. Mike did a great job with the installation, arrived on time, and worked with us on the correct height for the chandelier. We have used him before and will use him again.

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.

Installing new gable fan in attic gable vent. Fan has a humidistat/ thermostat combo unit attached to control fans running time. Attic fans help pull hot humid stale air out of the attic and off top floor of home out of the home so that nice cool air can move in. These fans can make anywhere up to a 10 degrees difference on top floors of homes and help to lower energy costs by making HVAC units not have to work as hard or long.
