September is National Preparedness Month, and it's the perfect time for us to remind you that preparing your home goes beyond stocking emergency supplies.

Take a few minutes to:
✔️ Test your smoke and carbon monoxide detectors
✔️ Replace HVAC filters
✔️ Schedule your furnace maintenance
✔️ Know where your main water shutoff valve is located

A little preparation today can help prevent bigger headaches tomorrow.

“Working with TF O’Brien has been a pleasure for the past two years.

Last week we replaced the water heater in the house and William was thorough, meticulous and left the work site clean. This was the second repair he had done at our house. I would not hesitate to recommend him for any plumbing related work.” -Dimitri N., T.F. O’Brien customer

“Chris was extremely thorough and professional. He answered all our questions very clearly and explained everything. I have used other cooling and heating companies in the past and none have come close to Chris’ professionalism, thoroughness and ability and patience in explaining everything. If I could give more than five stars I would.” -Robert M., T.F. O’Brien customer
