Report
I had a great experience with Westenn Mechanical! I needed a Spring clean and check and wanted to find out about improving the air quality in my home. I have allergies/asthma so I really need good filtration, and with fireplaces in the neighborhood it's a problem for me! My air conditioner also needed to be replaced (found out that it was a 1989). Shawn came to do the cleaning and discussed HEPA filters and took measurements and pictures of existing furnace and air conditioner. Ray contacted me with the specifics and pricing, and got me scheduled in pretty quickly! Shawn and Jeff arrived (early) and did a great job with the installation and instructions on new thermostat.
They totally cleaned up after themselves, which was great! It should be a given, but not everyone does this anymore! By the way, there was a fireplace burning in the neighborhood last night and my new HEPA filter totally kept the smoke smell out of my home! I would totally recommend this company to anyone!
