"The installation was done right away, done quickly, and done thoroughly. There was no mess left behind and the price beat all other companies by a LOT. The employees were polite, honest, and responsive. Other than having to pay for a large replacement project, this was a great experience!"

"Very professional and totally knowledgeable about his products and installation. He worked with me on trying to explain what was necessary for my job and didnâ t try to sell me more than I needed. In the end I did decide to replace The whole AC and Heating Unit for peace of mind through no press from him. He has a additional one year warranty on labor only if needed. He was here on a Thursday and started the job on Friday then finished on Saturday. He moved his schedule around to accommodate me so I wouldnâ t be without AC. He was dependable and on time. I know I can call him for my future AC issues if any."

"I wanted my front door replaced with a very heavy iron double door. Even though my husband is very handy, it was just to heavy and cumbersome for him alone. Joe came out and helped my husband with the heavy lifting and offered some good insight for the installation. Whole process only took a couple of hours. I was so impressed with him that I asked him to come back a few months later to install some drywall in the garage that we torn down earlier for a remodel. Joe did a great job. Always comes on time and has good ideas how to get the job done. Very dependable. I highly recommend him."

FAQs for thermostat installation and replacement projects in Greenwell Springs, LA

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.
