"Cory and Joe were fantastic. The installations went without a hitch. The overall cost was lower than three other quotes I had received for the job. At the beginning of the A/C install I noticed the water heater was leaking, and they were able to replace it the next day. I will definitely use them again."

"I had a hot water leak and he came out gave me a quote and replaced it next day upon my request. And I'm still waiting on the quote from the other two plumbing outfits. If you need quick and timely service and good personnel go with these guys. The two guys that gave me the quote were installers as well so they know what they are talking about."

"There were problems with the installation of the heating system. We requested that either the owner or manager come out to inspect and resolve the issues. We were told the owner would be out at 3 pm. When he did not show up, we called and were then told the appointment had been rescheduled for 7:30. When someone did show up, it was out the installer who had done the initial work. Although he did fix some of the minor issues, he was dismissive of the others and did not address them. We again requested that either the boss or manager come out. We were repeatedly told we would be contacted, but have not heard back yet.***UPDATE 12/23/2020: After HomeAdvisors assistance, we were able to get them out here and all the problems were resolved."

"I got lost in the shuffle for the work call after the initial estimate, but once we cleared that up, they did a fabulous job. Had two toilets, two bathroom sinks with faucets and kitchen faucet installed, and replaced two sets of shower hardware. They also replaced the garbage disposal. Great work by great workers. Very pleased."

"I had two Trane furnaces installed( replaced old gas furnaces). Not only an estimator spent lots of time inspecting the whole system , gave a detailed estimate. He was knowledgeable. Two installers arrived on time, out on shore covers and worked . They replaced duct systems on 1980 system with no extra charge. Cleaned up all debris when work was done. They explained how Bew system works. Very professional. Office did two follow ups and a year later , scheduled a complimentary inspection. I recommend them ."

"We had central AC added to our home 5 years ago. We decided to get an AC and furnace tune up before the summer. Matt, the technician from One Hour Heating and Air, was on time and polite. He pointed out that our furnace filter had not been changed since 2022. Big oversight by me. Matt explained how the air flows through the furnace and the direction the filter needs to be placed. I marked with a sharpie on the furnace an arrow so I would remember next time. Positive experience."

Customers say: Super punctual

"Jack and his crew are incredibly nice, knowledgeable, skilled, and easy to work with. They did a fantastic job, and were so respectful of our home! I hardly knew they were here half the time, they were so low-key. We had them do the baseboards and outer door frames on our living, dining, and hallway areas. We'd refinished the wood floors over the summer, and hadn't gotten around to painting and installing the new trim, and finally just realized we didn't want to do it ourselves, and hired it out. They completed the work yesterday, which was well in line with our agreements, and it turned out beautifully! I just walked down the hall, and said internally, "Wow, this looks so great." ? My partner said the same thing when he got home and inspected it. We're both impressed and pleased with it, and Isaac's attention to detail, and willingness to be super diligent for me, were highly valuable! We are already planning to hire them again, to do the trim in the kitchen, and replace a window in the garage that is broken. I highly recommend Jack, Isaac, and Josh."

FAQs for thermostat installation and replacement projects in Seattle, WA

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.
