"John was prompt and courteous. He was diligent and careful about his work which I appreciated. Our documentation did not show the codes the unit was showing. John ordered and replaced the unit and then researched the codes. When the new unit proved not o be the issue, he refunded the cost and worked through the documentation he found (not easily provided by the manufacturer). The unit is now working perfectly and we will definitely contact John for any future servicing required."

"Had Matt run new wire for a big addition and hook everything up. He was easy to work with, communicative, and fast. Very talented for a young guy. I was nervous about some potential complications but once we turned everything on, zero issues"

"Jonathan came to check out our situation. He walked me through our choices for new toilets & install cost as well as the option of repairing our current ones. We decided to replace 3 toilets, I purchased them and he installed them. Everything is working great!"

"We were told that our compressor would need to be replaced. Go cool service not only did a fantastic job of checking everything out and doing a great diagnostic, but he saved us a fortune by finding out that it was the fan instead. He was honest and knowledgeable. One of the really great contractors. You hear about so many bad ones that are trying to cheat people but he is one of the good ones. Very honest and respectful contractor. Should be first on everyoneâ  s list."

FAQs for thermostat installation and replacement projects in Thornville, OH

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.
