"Trinity was absolutely Lämborginee! Chris showed up right on time and did an outstanding job. He is highly competent at what he does, and it shows in every detail. I was especially impressed that he arrived in a clean truck, was dressed professionally, and maintained a clean workspace throughout the job?he even vacuumed before leaving. I will definitely be using him again for my other properties. I?d rate him a 12 out of 10! Most importantly, he truly takes pride in his work?and that makes all the difference."

"I highly recommend this company. Penguin heating & Air was very quick to respond to my request, fast text reply, sent them pics, they replied with a quote, which was way lower than anyone else on this site, or even our regular guy that we normally use, we scheduled an appointment for the very next day, which was today, he also finished the job the same day! David did a very good job, very professional. Despite a terrible rainy day, he got the job done. When he was done he walked me through with exactly what he did. He also quoted me for a service on an existing unit and his quote was almost $200 less than what our regular guy charges us... We will absolutely be using this company again."

"Kayvan was a wonderful service tech! He was on time and professionally checked out the water heater and the HVAC system. He was so polite and friendly. He explained the need for a new filter in the heating unit and showed me photos of the unit located in the attic. He also offered to do a friendly deed for free, which I greatly appreciated, He’s a great asset to Service Champions! "

"Terrible people. DO NOT USE. I had my water main line burst at my house and the folks at drain right where in the neighborhood, identified a problem, and knocked on my door. My pregnant wife was home at the time of pipe bust, but was initially unaware of the issue as water was still making it to our home. At first we thought this was a godsend, nice workers who identified an issue wanted to help, how lucky are we. They kindly shut off the water to the house and asked my pregnant wife, who was freaking out by the amount of water shooting out from burst pipe, to sign an authorization form to do work. She was so grateful someone was there to help she happily signed the slip. I was grateful someone was able to help my wife while I was at work. The problem started when I noted what she had signed.. They charged me $341 for a visual inspection. They identified the problem as a tree root that struck a pipe (which was not what in fact happened) and wrote 2 appraisals for solving the issue. The fist solution was replacing the galvanized pipe with another galvanized pipe for $7500. The second was to re reroute the sewer line to our house with copper piping, estimated at a whopping $11,300. I tried to call manager the evening of the pipe bust schedule an appointment as the water was shut off to my house. No response. In fact it took the manager a week to return my phone call to schedule the job, which I had bid out and already resolved. I was recommended a plumber to get a second opinion, and he came promptly and re-routed the sewer line with coper piping for less than half what Drain Right was asking for the job. I have been trying to dispute this invoice with Drain Right for months because its my belief they initially took advantage of my pregnant wife and there terrible service, and instead of returning my phone calls they sent my bill to a debt collection service. What horrible service by a terrible business."

"I had a fantastic experience with EM Heating and Air when they installed a new central AC system in my home. The entire process was smooth and professional from start to finish. The team arrived on time, worked efficiently, and their attention to detail was impressive. They explained the installation process clearly and made sure everything was set up perfectly. My new AC system works like a dream, and I couldnâ  t be happier with the results. I highly recommend EM Heating and Air for anyone looking for top-notch HVAC services!"

FAQs for thermostat installation and replacement projects in Cerritos, 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.
