We've had very good service from F&S from plumbing to HVAC. The last time they visited, they recommended less frequent service on our water softener based on how clean it was. This wasn't the first time they've recommended something that might cost them a little business, but would save us money. I feel like such suggestions are really a mark of an honest business!

An exceptional company with great customer service! Always responsive, great service (will always explain issues and options), and competitive pricing. F&S Williams is our first call for any HVAC, plumbing, and even light electrical work. Cannot recommend them enough!

Three Technicians from F&S Williams worked very efficiently on installing a new gas furnace and ac system in our home in Brookston. The installation location in the basement was somewhat challenging but the furnace installed in a professional and high quality manner as was expected for a HVAC company in business for 70 years. The Techs were very polite and considerate.

The following day I had a flexible liner installed in our tall chimney by two of the same Techs from F&S. They offered suggestions and kept me informed on the process. They were attentive to my concerns and questions during the whole process. I am very satisfied so far and the furnace is working to our expectations. I am confident that the ac system will also give us a satisfying performance during the next cooling season.

Upgrades on your house can be expensive and overwhelming if you lack the knowledge and understanding of your systems. F&S Williams were thorough in their inspection and took ample time to help me understand our entire HVAC system, so that we can make informed decisions moving forward. They were responsive, friendly and respectful. I look forward to working with them.

Quick and professional. They did warranty work and maintenance on my water heater. I have used them for over 20 years and I know my home is in good hands when they come. The techs were friendly and courteous and made sure things were right Service: Water heater repair

Austin and Chris were awesome when replacing my water heater. They were prompt, courteous, and simply fun to talk with. They explained things really well about what went wrong and the costs of repair versus replacement. This is the second time I've used F&S Williams and everyone I've worked with has been great.

I was impressed with this company when my landlord had them come out on 2 separate occasions, once for an ac repair and once for a furnace issue. Both times the technicians were to the point and honest about what the repair extent needed to be. These 2 positive encounters cause me to hire them to inspect and clean my new (to me) furnace! Very straight forward on what needed fixed and what did not!

I asked a good friend who he would recommend and he pointed me to F&S Williams. They have done great work for me and I am very satisfied with their professionalism and work. They were respectful and cleaned up thoroughly when they were done. I feel like I got good value every time they have worked for me and my family.

We had a our furnace, AC, and hot water heater replaced and everyone at F&S that we interacted with from day one was professional and outstanding in their service. From the initial quote to the quality of their workmanship by the crew, I was very pleased with the final product and service we received. I would highly recommend F&S Williams for your future HVAC and plumbing needs.

I have been an F&S Williams customer for many years for electrical, plumbing, heating, and air conditioning. I am impressed by the quality of their work and what I consider to be very fair prices for the work they do. They are always quick to respond when I call for help, particularly if it is an emergency. Their technicians are always prompt, courteous, and explain fully the problem and what needs to be done to fix it. With me, they have a customer for life!

I found F & S Williams extremely helpful when my air conditioner froze up. They had a technician at my home quickly (same day!), he was very thorough and took the time to explain in detail exactly what the problem was. I ended up replacing my 15 year old unit. The technicians were here on time (the next morning), they respected me and my home, cleaned up after themselves.

I am thrilled with the new unit! It was reasonably priced and has been working perfectly in our current heat wave. I would not hesitate to recommend this company and their wonderful employees to anyone dealing with an air conditioning problem. --- L. Champion

Called them on extremely short notice (day of issue 6/14/16) and I asked for noon and at 12:15 they were working on the system. Was very happy with the service and very knowledgeable and also let my father and I know everything they were doing. My current system is 27 years old well maintained so it goes without saying im happy it still works. I would highly recommend them.

I used to use Lafayette heating and cooling an not that there was any issue its just I wanted to try this company plus I know the owner. They also installed a new hot water heater 2 years prior to this month. An that was very short notice as well. So I appreciate there service.
