"Rene and Maurico installed a new air conditioning unit in my home. They negotiated fairly and were responsive to my questions. A team of five arrived for the installation. They worked together like a well tuned machine. Everyone knew what they had to do and when to do it. There were no mistakes. They were here by 8:00 am and were finished by 4:30. They answered all my questioned and responded to my phone calls. They were polite and respectful. They cleaned up after themselves and left nothing damaged. More companies should operate like them. I would highly recommend them"

"Beware of Brian Hoffman, DBA “Premier Services”. I agree with all the negative reviews here - I had the same experience. He did a bathroom project for me October ‘24. He did a poor job, including an improperly installed toilet that was leaking under the floor. He agreed by text message to a $300 refund in Nov. ’24, but still hasn’t paid as of the end of July ’25, even after losing in Small Claims Court. He uses multiple addresses in various LI towns and won’t tell you his actual current address. The one listed on Angi is a street that does not even exist. Now he won’t respond to texts or phone calls."

"Overall, careless and sloppy. He had one guy that was dependable but he was constantly pulled to work at other locations. As result, my projects were put on hold. Mike tried to complete the jobs himself but simply made things worse. Had to find someone else to the job and clean up his mess. Not worth hiring. Do yourself a favor, save time and money and find someone else."

"Very pleased with this company. Professional, timely. Our home, porch, shed, and stairwell are sparkling. The two workers were polite and efficient and when I questioned why my office window looked like the soap was not rinsed he advised that they rinsed it twice (2nd story) and offered to clean it again. It is now perfect. This is a difficult window for us to access."

FAQs for thermostat installation and replacement projects in Port Jefferson, NY

Smart thermostats may be worth it for many homeowners. They come with various features, including voice control and smartphone apps. Vacation mode can help lower energy usage when you’re out of town for an extended period. Alert warnings let you know about major spikes or drops in temperature. Smartphone apps can track energy usage, and smart thermostats can learn your routine over time to adjust your temperature and reduce wasted energy consumption automatically.

You typically do not need more than one smart thermostat. While it’s common to see multiple mechanical thermostats throughout a large home, multiple smart thermostats may try to override each other. This can lead to problems with the HVAC system. Ensure the unit you buy has the option for dual- or multi-zoned systems to avoid compatibility issues.

Installing a programmable or smart thermostat may save you $180 per year in utility costs. A big part of this comes from a smart thermostat’s ability to learn and adapt to your regular routines. With smartphone apps or web-based interfaces, you also have the option to control your thermostat when you’re not home.
