"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."

"Carlos was knowledgeable and honest. I greatly appreciated how he not only installed our new smart thermostat but also went out of his way to check our HVAC system and give us pointers. Also appreciated him not selling us any other repairs or products."

"Quality of the rack replacement was excellent. Only issue I had is that the closet door that was removed, wasn't replaced the same as it was before. However, I would definitely use Victor again and recommend him to others."

"We had a TINY bathroom with almost no storage. It was so small, we could barely turn around in it. Tony came in, listened to what we wanted and immediately designed a remodel. He worked with our budget and did not try to sell us on extras we didn't need or want. His crew was neat and punctual. The job was completed in a reasonable amount of time and best of all, we got EXACTLY what we had hoped for. Two thumbs up for TME!"

FAQs for thermostat installation and replacement projects in Pasadena, 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.
