Just wanted to say thank you to Blake Hitch for his professionalism and outstanding customer service! I had never used First Class before and I needed a new hot water heater and thought I wanted to go to a tankless. I went thru the Home Depot website and they referred me to First Class. Blake came out last week to do a quote. He listened to what I wanted (or thought I wanted) and explained to me how a tankless really worked. He then discussed the other options I had. I made the decision that evening and a week later here he was with his helper and installed my new hot water heater. I had to do NOTHING! He ordered it, picked it up and delivered it to my home. Proceeded to remove the old one and installed the new one. Made sure All was working as it should, registered it and even processed the extended warranty. I literally had to do nothing!! Very unusual on the Eastern Shore to receive this quality customer service. Being in the customer service field I more than appreciated. First Class is lucky to have an employee of this caliber! Thank you again Blake!!

To First Class, thank you so much for a job well done. I love my new furnace and A C unit. Josh and Tom Hurst were great and they explained everything and I understood it too! Thanks for everything!

Arrived at our second home only to find that our heat would not come on for what was the coldest night of the season so far. Called First Class, as well as others, and they were the most responsive to an emergency call. RJ arrived on time Saturday morning and quickly diagnosed the problem - mud daubers had completely blocked the vent preventing the furnace from igniting. RJ got it cleared, with no small effort and had our heat running again in what seemed like no time.

Compared with others that we had contacted, the price was very fair. To prevent future issues, we will be entering into a service contract with First Class. Look no further, these are the folks to care for your HVAC.
