"The only thing that they found wrong was the thermostat cover was loose. I replaced the batteries and the cover was replaced by Rep and it started working again. He did say that capacitor did need to be replaced, soon or a new system needed to be purchased. System in attic was checked, too. Quote for new system was given. Conscientious employees."

"My 5 ton AC unit died after 14 years of use. I took in 4 vendor bids to replace the unit. Enoch was excellent to work with. Better than all the rest. Enoch listened, they taught me what to look for and we worked together to get the best return for my money. Enoch won the bid. Their workers were timely, very professional and cleaned up after themselves. I am so pleased with the Enoch work. Honestly I was very concerned to select the right AC vendor and installer. This was a huge expense for us. In the end I could not be happier with the Enoch implementation."

"Blake did an excellent and thorough job. We had a leak that he diagnosed and fixed which ended up being a roof issue. He repaired some exterior window framing and also installed new tile floors. He is very detail oriented and his work is impeccable. I have already referred him to neighbors and will definitely use him again."

FAQs for thermostat installation and replacement projects in League City, TX

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.
