Yesterday, I opened my washing machine to do laundry and water came gushing out of it. I called two different appliance repair companies and Thomas was able to provide the earliest appointment at 8:00 this morning. Mandy in dispatch was fabulous. She had me laughing the entire time. Tom arrived right on time. He figured out the problem very quickly. Tom was so honest. He explained that the washing machine was from 2008!!! It was here when we bought the house a few years ago. He said we could pay to fix it, but other parts were also bad. Tom recommended buying a new washing machine. Tom made a suggestion as to who to call and stayed with me while I made the call and ordered the washing machine. He went above and beyond. Tom easily could have left as soon as I decided to not do the repairs, He made sure I selected a washing machine that met our needs. It will be delivered in the morning. What could have been an absolute nightmare turned out to be incredibly easy. You would be well served to use Thomas Home Services for all of your home repairs. I certainly will in the future.".

Why Choose Reverse Osmosis?
Reverse osmosis systems use a multi-stage filtration process to remove contaminants like chlorine, lead, nitrates, PFAS, and other dissolved solids—leaving you with pure, refreshing water for drinking, cooking, and ice-making.
Benefits of installing an RO system:
Cleaner taste – removes chlorine, sediment, and unpleasant odors.
Better for your health – filters out harmful contaminants.
Saves money – reduce bottled water purchases.
Eco-friendly – less plastic waste from single-use bottles.
