"Perfect Star has excellent technicians who can do installations & any service needs. They installed a new AC/heating system a few months ago. I intend to hire them again to update the ductwork in my residence. Tech was out today to tweak the thermostat setting to get max AC flow."

"Truthfully, we had angst about calling for service because of past experience with other HVAC vendors. They always said the same thing, our system is "old" and we need a new one. Very expensive! We called for service, not a hard sell! Hence, we never used the same one twice. However, Tyndall gave me the impression, whether right or wrong, that they would be less likely to do this so I decided to try them. They kept me informed of their arrival status, since they squeezed me in at the end of their work day the same day I called. So, communicative and accommodating! After running several tests, they determined it was an electrical problem and nothing to do with the unit itself. They also said our unit doesn't need replacing - that's a first! They didn't do any unnecessary service or repair to run up the bill or even try to convince us it was needed. We were only charged the minimum fee as quoted. We were able to repair our air conditioning without the "hard-sell angst". So, thorough and honest! Unlike the other HVAC vendors we've used, we definitely will call them if we need service again!"

"I highly recommend Josh Matus from SC Home Repair. We needed to have a ceiling replaced in a closet after it was damaged by water. The plumber who originally fixed the leak cut out the ceiling to fix the leak, but was not able to reinstall it. We hired Josh to replace the ceiling. He did an excellent job. He was punctual and polite, and kept me looped in on the entire project. He got my sign-off on all of his decisions and ran pricing by me when he needed to buy supplies. He knew exactly what he was doing. Josh finished the job quickly in two days and did excellent work while paying attention to detail. I would certainly hire him again!"

"Overall experience was average. First day of installation was okay until I find out half of the house did not have power. Edgar came back the next day and explained the cause and fixed it with ease. Was getting push back about how everything was installed as it was and there shouldnâ t be any issues, well there was and he graciously came back and fixed the problem. I would definitely use this company in the future."

"I have hired Real Handy Handymen on several occasions for work both at my business and home. I find them an extremely knowledgeable, timely, clean, and hardworking team. Tasks they have completed for me: Interior and exterior painting (not just slapping paint on, doing the requisite prep work as well) Rebuilding of antique windows Replacement of exterior deck boards Recaulking of shower glass Installation of interior doors Complicated Installation of through the roof venting for laser cutting machine Repair and replacement of plumbing elements and water heater elements There simply hasn’t been a project that I have thrown at them that they have not been able to complete to perfection. They show up on time, work quietly and efficiently and do the highest quality work. I cannot recommend them highly enough."

FAQs for thermostat installation and replacement projects in Walnut Creek, CA

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.
