"Trinity Heating installed a new thermostat in my house. The technician, Jimmy, was professional and courteous. After the installation he took the time to explain to me how to set up and use the new thermostat. I’m completely satisfied with their service and will use them again if needed."

"My wall heater had not been working for 3 yrs and I could not find anyone to fix it. This young man and his brother came out when I called checked out my situation and explained everything to me and my husband. They were very knowledgeable and professional came out the next day on time and replace my whole heater. They protect my floors, cleaned up and now my home is warm and the new heater looks great."

"It was amazing. Guilmar was professional and did a great job replacing the lock on my sliding door. There was good communication about his arrival and he was able to see me the same day. I am very pleased and will definitely hire him again."

"He serviced my air conditioning unit, took care of two leaks in the unit and replaced my old thermostat. The unit itself works better than it even did when it was first installed."

"Tony at TME Construction was very professional, accurate and reasonable with his price quotes, and accurate with his project time line estimates. As always with these extensive remodeling projects, there were a few hiccups along the way, but his response and ability to adapt to our changes and requests without adding on any significant cost to the total made us very satisfied at the end. Tony's and his team are top notch and the quality of work that they produce are second to none. Here's the full story of how it went. My wife and I purchased a home with the plan to remodel the entire kitchen and replacing the carpet/tile with wood flooring. After we had placed the order in for the cabinets and the appliances we wanted, we started to look at contractors who could perform the entire job and spoke to 4 different contractors and got various quotes. Tony at TME Construction wasn't the cheapest quote we got, but he also was not the most expensive. He was just around the average price quote we got. What made us eventually go with him was a combination of his numerous reviews, his knowledge and experience with kitchen remodeling projects, and his reasonable price. When I agreed to hire him, I told him that I wanted to use my own painter and my own electrician. This was because I felt that his quotes for painting were a bit higher than I got from another painter that was recommended to me, the same with the electrical work. The tricky thing about hiring a general contractor like Tony, and then also hiring out your own sub contractors, is now you need to coordinate all of the parts. At first, this seemed doable, and it went okay. But eventually, I started to see the flaw in my thinking because the few thousand dollars that i saved by hiring my own electrician, painter, and demolition person, ended up causing me a lot more grief in the end. So the way that my electrician had run the wires through the walls, didn't work for the way that the cabinets were being hung. So Tony had to fix the work of my own electrician. Luckily, he didn't charge me an arm and a leg.. maybe just a couple of fingers. If I had to do it all over again, I would just let Tony handle everything from the beginning, despite the higher cost. Tony's team is very competent. You could tell by the quality of work when it came to installing the cabinets and making sure they were all lined up properly, to installing the giant countertops, to making sure that the appliances were all installed correctly. What I liked about the way Tony works is that he hires the expert he knows for a particular job. He does not have a bunch of generalists that can do everything. He has a specific tile guy, a specific electrician, a specific cabinet installer, etc.. What this means is you get very knowledgeable people for each job. In addition, Tony himself is on the job and doing the work as well even though he technically could have his employees do it for him. He was there checking the work at every stage and making sure that things were done correctly. If something was not right, he would have someone redo the work until its right. The estimated time to complete the full kitchen remodel was about 3 to 4 weeks. It ended up an extra week and a half due to circumstances out of his control. We were waiting on parts that didn't come in time. Even after I had paid him in full, which was after the job was completed, he was still very responsive and dealt with any questions I had regarding things that I had issues with. For example, our Thermador freezer's ice maker was not working. I called Thermador first because I thought that the ice maker was broken. Thermador sent someone out and the person said there was no water coming in from the line. So I called Tony back and said that the water line was not hooked up correctly. Now with a 60" fridge and freezer, this was no easy task to remedy. Tony sent 3 guys from his team to look at the problem. They pulled the massive fridge and freezer out from wall to diagnose the problem and eventually figured out that the person who I hired to demo the original kitchen, also removed the line that sent the water from the sink to the back of the fridge. They added a new line to make the connection and the ice maker was fine. Despite this not being Tony's team's fault, he was still willing to send his team to remedy the problem because he cared about our overall satisfaction as a customer of his. If I have another major remodeling job in the future, I would not hesitate to hire Tony at TME again. In fact, I recommended Tony to another friend of mine who wanted to remodel his kitchen, and Tony did a great job there as well. The only thing I'd do differently is not try to hire my own workers to make the job cheaper, because it just added unnecessary complications and it didn't really save me money in the end."

"Service was great and pricing very competitive. Nick Knuth was very knowledgeable when he came to do an assessment of the work to be done, and answered all my questions I'm a very clear way. The techs worked pretty quickly and efficiently when installing the new unit. Deisy and Emma from the office always made sure that things were taken care of and went above and beyond with follow-ups and updates. I would definitely recommend them to anyone who needs this service."

FAQs for thermostat installation and replacement projects in Los Angeles, 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.
