"My appointment was on Monday 1/5/2026 to fix a leaky shower faucet that had continuous running water. Jordan Benavides responded and came to the job ill-prepared and without the proper tools to complete the work. He went to Home Depot, came back and still didn't do anything. He had one excuse after another and spent more time at his truck than on the job. I have him on videotape going to his truck 15 times, even sitting idly one time for 15 minutes. He charged $530 for the job and tried to price-gouge me for more business. After 2 hours of him stalling, I called dispatch and sent him on his merry way. I was left with a leaky faucet and a damaged shower handle which was working before. I called another company to fix the handle and solve my problem. If Jordan is indicative of the caliber of technicians Casteel employs or subcontracts, I will not be doing any further business with Casteel. "

I have been in the construction industry for over 25 years. As a homeowner needing to get things done that I do not have time to do, I tried to hire people to do the work for me. If I contacted companies, they did not answer the phone and if you left a message they did not call back. If they did call back or they would schedule appointments and never show up or if they did show up you would never hear from them again. If I was lucky to find one that provided an estimate, they did not know how to do the projects requested. Larger companies do not want to do the "little" things. At the point of getting so frustrated, I decided to start this business so that other homeowners would not have to go through this. I have hired professional and qualified people; drug test and background checks have been performed on them to ensure clients safety. The technician comes out, accesses the work and pricing is given on site. If pricing is accepted, the technician will perform the work immediately. You do not pay for the work until the job has been completed to your satisfaction.

"Customer service was superb and concise. The information about what was to be done was excellent. The handyman was experienced and completed the job in a timely manner!"

FAQs for thermostat installation and replacement projects in Marietta, GA

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.
