"I contracted with Grant Heating & Cooling Inc. to install HVAC system in my home in the spring of 2024. They were very professional and did a very good job. In the winter of 2025 I had a minor problem with one of the Mitsubishi heat pump system units. The company was quick to troubleshoot the situation. The technicians were courteous, knowledgeable about the system and thorough. It required several visits to diagnose the problem and fix it. The manager, Nick was very responsive to the situation which required bringing out an expert from Mitsubishi. All of this work was covered under my warranty. The problem was fixed and I could not speak highly enough about the company’s policies and customer service. I would highly recommend them for all facets of their work and standing behind their installations. I am very happy to be working with them for my continued maintenance. They are an excellent company. Sincerely, Susan Coursey"

"The fix was straightforward, had to replace the AC blower unit motor. Garmer handled the task expertly and with great customer service, despite them discovering an unusual screw installation from the prior owner which caused the housing removal to take a bit longer than they initially anticipated and first quoted (which, if you've owned a home, tends to happen somewhat often as equipment of this magnitude usually can be more complex than they first look). The only thing I would suggest is that they re-address their pricing. This job ended up costing around $1,200 to change a blower motor where the part itself probably was no more than a few hundred (final bill was delivered upon completion) - was estimating maximum $1,000 given their guidance throughout the job. At a certain point, it may make sense to give the customer a flat project fee as opposed to remain on hourly labor billing as the crew is trying to re-assess to avoid customer sticker shock and alienating future work. I respect the crew, the work they did, and value their labor, but believe the pricing is high. I would like to stress that I would recommend and would consider using them again simply because of their expertise, customer service, and responsiveness as they do great work, but would be more critical of the price ahead of time."

FAQs for thermostat installation and replacement projects in Mattituck, 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.
