"I had to replace my old boiler heat as it was not repairable. So I purchased a NEW wall-mounted, modulating gas, condensing, combination Boiler. It replaces BOTH my boiler heater & Hot water tank. The new unit is attached up on wall with a small tank, gas, water lines below. The 2nd pic is where old hot water heater used to sit. Now I have all that extra storage space!! And no need for upkeep & repairs on a big old hot water heater!! The only thing I can complain about was that they were here for 12 hrs!! start to finish. Plus I was here sitting practically on top of a space heater dressed very warmly all day. And of course this was in January 2025 in northwest Indiana. I think this was a 1st time install for them in an older home not a new build. I would have rated them as a 5 star if not for the LONG DAY it took to be installed. They all were very nice, kind & cleaned up their mess. They brought large painter cloths to put down on floors due to going in out in the snow also."

The quote was very reasonable, and they were able to do the work shortly after their initial visit. They replaced everything with Liberty pumps. Justin and Erich did the work and they were very professional. We had them quote out a couple of other items (replacing water heater, etc) and those quotes were also very reasonable. I will definitely hire them for future jobs."

We are a Heating & Air conditioning company that specialize in heating & air conditioning installation and repairs.

"The technician was very professional and respectful of my home by removing and/or covering his shoes as needed. He kept me informed about his progress and issues he found as he continued his work. The furnace is very old, so he conducted research, determined the problem, got the needed parts and completed the job for a reasonable cost. I would definitely use his services again. 5 stars!"

"He was supposed to start on November 9 called off and did show up on November 10 to install the thermostat that I provided. He worked on it for couple hours and then told me that the thermostat was faulty. He told me to return it and he would buy one and return the next day. After he left, I noticed one of the prongs were bent and I straightened it out and the thermostat worked and the heater kicked on. He still maintained that it was faulty, so I did return it and he came back with one exactly like it the next day. I reimbursed him for that. Again, he worked on it for a couple hours and the same issue that we’ve had from the beginning of the fan not turning off remained. He told me that there is no way it’s wired wrong so it has to be in the unit asked for payment which I gave him $125 in cash. I might add that he used my tools which I found quite odd. I ended up having to call out another contractor because he told me it had to be the unit. Cliffs informed me that there was absolutely nothing wrong with the unit and he even referred to it as “Cherry“ He checked everything out and then asked me about the thermostat and I said it was brand new and installed through Angi. He took the cover off and in a split second said I see exactly what the problem is. It’s c wired wrong. (THIS WOULD MEAN THL WIRED IT WRONG TWICE) He pointed out the green wire should not be connected at all. That is what is making the fan run continuously. He disconnected the wire and it worked perfectly. This cost me $218.00 for the service call/tune up."

Thermostat installations and replacements FAQs

It's often worth replacing your old thermostat with a newer model that can enhance your home's comfort and energy efficiency. Upgrading to a programmable or smart thermostat can save you up to $200 per year on energy bills. Plus, smart thermostats offer convenient features like remote control and learning capabilities, making your home more comfortable and easier to manage.

Signs of a bad thermostat include your HVAC system not turning on when it's supposed to or failing to reach the desired temperature. If the thermostat's display is blank or not functioning properly, it could be malfunctioning. Another indicator is the HVAC system running continuously without shutting off or cycling on and off too frequently. You might also notice uneven temperatures throughout your home, with some rooms being too warm or too cold. These issues suggest that the thermostat is failing and may need repair or replacement to ensure your HVAC system operates efficiently.

A thermostat should last between 10 to 20 years, depending on its quality and how well it's maintained. Over time, dust, wiring issues, and general wear can affect its performance. Even if a thermostat is still functioning after 10 years, you might choose to replace it to take advantage of newer energy-saving technologies and smart home integrations. Upgrading to a modern thermostat can improve efficiency, offer more control over your home's climate, and potentially lower energy bills.

The number of thermostats you need depends on your home's size, layout, and heating and cooling zones. In a standard single-zone HVAC system, one thermostat controls the temperature for the entire home. However, larger homes or those with multiple floors might benefit from multiple thermostats linked to a multi-zone HVAC system. This setup can offer better comfort and energy efficiency: It lets you customize the temperature in different areas, so you're only heating or cooling the spaces you're using.

Replacing a thermostat typically takes a professional technician about one to two hours to complete. If you're swapping out an existing thermostat for a similar model with compatible wiring, the process can be done in less than an hour. However, installing a new thermostat that requires additional wiring, such as a smart thermostat, or moving the thermostat to a new location can extend the time to two hours or more. Complex installations may also involve cutting into drywall or integrating with other home systems, which can add to the duration.

There are a few things that can cause your home thermostat to fail. The most simple one is age and cleanliness. Dirt, grease, dust, and other small particles can clog sensors and cause malfunctions in readings. You may also have a failing power supply and loose connections, and the simplest cause is that it isn't installed in the right place in your home so it can't properly sense air temperature. Repairing a thermostat costs around $210.
