FAQs

Common Questions About Thermostat Installation & Upgrades

A programmable thermostat follows a schedule you set, raising or lowering the temperature at set times of day. A smart thermostat does that and more. It connects to an app so you can adjust settings from anywhere, and some models learn your habits to trim wasted energy automatically. Plumbing Masters installs both and helps you choose the one that fits your routine.

Not every thermostat is compatible with every system, which is why we check your equipment and wiring before recommending a model. Plumbing Masters matches the right thermostat to your heating and cooling system, replaces outdated controls and handles the entire setup, so you do not have to worry about compatibility issues or a thermostat that does not work as expected.

It can help. A smart thermostat cuts wasted energy by adjusting temperatures when you are asleep or away and by letting you make changes from your phone instead of leaving the system running. Learning models adapt to your habits over time. Older controls often waste energy and comfort, so upgrading is one of the simplest ways to improve efficiency.

Yes. Plumbing Masters installs Nest thermostats along with other smart and programmable models. A Nest brings smart learning to your home, adjusting temperatures automatically based on your routine. We confirm it is compatible with your system, install it, connect it to the app and make sure it is working properly before we leave.

Yes. After installation, our team builds a heating and cooling schedule around your routine and connects your smart thermostat to its app so you can adjust schedules and temperatures from anywhere. We also show you how to make changes yourself, so you are comfortable using your new thermostat from the first day.

Had an issue with my new dryer. I smelled gas when opening the dryer door. Rick came out and determined there was a faulty gas line. He replaced it with a new flexible line. Everything is working fine now.

Needed to have the kitchen drain line cleared for the first time after 30 years in the house. Was able to schedule service promptly, which was handled professionally and competently. I think the price for the drain cleaning was reasonable, though it is a bit higher than what is seen sometimes in online advertising from other companies. Have been using plumbing master’s for many years and things are always handled competently by respectful and knowledgeable professionals.

Recently needed a (very old) dripping shower head/faucet replaced. Called on a Friday and appointment was scheduled for the following Monday. Bobby did a great job! Prompt, professional, courteous and the shower works again! Great service at a fair and reasonable price. I will definitely use Plumbing Masters for future needs.

Yesterday I reached out to get on schedule to replace my outdoor spigot. Lucy was able to fit me in today for repair. Lorenzo was amazing! He got me fixed up in no time & walked me through steps to prevent line from busting/freezing next season! Shout out to Jared & Brian from previous repairs! Every experience I’ve had with Plumbing Masters has been great! Highly recommend!
