"Dave did great work for us. We wanted to update three bathrooms. Dave replaced the floors, vanities, mirrors, and all the fixtures. He also brought in a subcontractor to reglazed the tubs. Dave finished on time, on budget, and the work looks great. I will definitely call Dave next time I need a contractor or handyman."

"HVAC Experts was one of the best experiences I have had with a contractor and home improvement! I was able to get a quote based on some basic information I gave to Alex which was to be verified onsite if I moved forward. I really did like that since I am a very busy person. The price was very competitive but as we all know that is only one component, its all about the quality of the product and installation. I was able to schedule the installation for a day and time that worked for me and on the day of installation my doorbell rang promptly at 8am. I did notice them parked outside early but I did appreciate them waiting to start exactly as promised. The initial crew were very nice and got to work right away then the company labeled van showed up with my new unit. Alex eventually showed up and did a walk through, I really appreciated him taking off his shoes which shows respect and making sure I was comfortable with the process. He also was very patient with the numerous questions I had and I also did a last minute upgrade to a Nest thermostat which he was able to run out and grab for me with no problem! Glad I did that we love the technology is brings. The removal of the old unit and the install of the new unit with this 4 man crew only took 3 hours and at the end the crew completely cleaned the area and Alex did a final walkthrough making sure I understood how to use the new HVAC unit and thermostat. He also tested the heat and cold and took temperature checks to make sure the output was as expected. We settled on the bill and I got an immediate receipt via email with the details. Top to bottom was very impressed with HVAC Experts a newer company but you can tell they have many years of industry experience! I now have a brand new AC unit and it’s working great!!!"

"My home had a very old AC unit that gave out on us this past summer. It has been very difficult for our family to find a dependable and reasonable company to come out to our home. I called ZRO and spoke with Josue on a Monday and was able to come out that same week with his technicians, they gave me a good deal and was very communicative through the entire install. Thank you!"

FAQs for thermostat installation and replacement projects in National City, 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.
