Can a programmable thermostat really save me money?

Yes! Programmable thermostats are easy to use, and dialing down the temperature (even just a few degrees at night or while you’re away), can help reduce your utility bills. We also carry wireless thermostats for added convenience.

We can provide an accurate estimate after assessing the problem in person. Quoting prices over the phone often isn’t fair, as many issues can only be identified on-site. Our approach ensures transparency, giving you a true cost upfront after a qualified team member diagnoses the problem.

Yes! Whether you’re planning a bathroom remodel or updating your air conditioning system, NES can help you find a financing plan that fits your budget. Speak with a representative about available options or apply online today.

It’s your choice. If you have the tools and expertise, minor repairs can be a DIY project. However, attempting a job without experience can make the problem worse. Most homeowners find it’s easier and safer to let an NES plumber handle even small tasks, ensuring the job is done correctly and fairly.

Most homes already have a backflow preventer installed, but older homes may not. Backflow preventers prevent contaminated water from entering your plumbing system. Ideally, testing should be conducted annually. It’s required for most commercial buildings in Michigan and is recommended for residential homes as well.

It’s important to call a company with the right experience and equipment. At NES, we can diagnose, service, and repair drainage and sewer issues for both residential and commercial properties. No job is too big or too small.

Replacing your furnace filter regularly is one of the easiest ways to maintain efficiency. A dirty filter reduces airflow, preventing your system from working properly and often causing “no heat” calls. Replace filters at least every 3-4 months during the heating season; helpful reminders include Labor Day and New Year’s Day.
