EXCELLENT Based on 1218 reviews Posted on Ken LTrustindex verifies that the original source of the review is Google. Thomas Home Services has been outstanding. Today (05/18/26) - Stephen came to my home to perform pre-season a/c inspection on 2 brand new a/c units they installed last year. He was very thorough and made sure the units were performing perfectly. Last year, their installation team was excellent and paid attention to every detail. I was so impressed with the caliber of their team, I signed-up for their Home Warranty and their Loyalty Club home maintenance program. Everyone who comes to my home is professional, has experience in their respective trade, and has impressed me, which is difficult to do. Now, when I need home service, I know one of the excellent Thomas Home Services team will arrive quickly, dressed properly, prepared with the tools, experience, and parts to do the job correctly the first time. I have referred Thomas Home Services to friends and family. I do not work for, nor related to anyone at this company. They provided a/c service to me in the past and called me to do an a/c inspection last year. They gave me a price to repair both units, repair one and replace the other, and replace both units, which is what I decided to do. Will, the owner, was involved in the transaction when I chose to replace my old a/c units and when I signed up for the warranty and maintenance programs. He was very fair to work with and I appreciate that he took an interest in making sure that I was satisfied. As long as they continue to provide this level of service to me, I will remain a loyal Thomas Home Services customer.Posted on D STrustindex verifies that the original source of the review is Google.

Marco went above and beyond to investigate the issue and my dryer is now back to it's quiet self! Will definitely use them again.Posted on Gwen Jordan HubbardTrustindex verifies that the original source of the review is Google. The technician was honest in letting me know I wouldn't need a tankless electric water heater and gave me the reasons why it wouldn't be efficient or cost efficient as well.

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.
