We take great pride in our experience, expertise, quality, and customer service that we provide to meet the consumer's needs. It is our mission to provide excellent workmanship and complete customer satisfaction, from the start to the completion of a project. In order to understand the needs and expectations of our customers, we take great care to work and communicate with every customer in a professional manner. Our reputation is based on service, safety, and quality, regardless of how large or small the job.

"We hired Juan to installed new subway backsplash and remove old peel & stick backsplash from kitchen. Juan mentioned he was a little busy but will be able to take the job on and complete it on a timely manner. Juan installed the backsplash on a Friday evening after 4pm and worked until about 10pm to get the backsplash completed. Juan returned on Sunday after noon to complete the tile work after allowing mortar to dry. However, the issue was Juan did not wipe up access mortal and/or cleaned off the tile. Juan left drops of mortal on our floors (which we had just cleaned from Stanley Steamer). Juan left a few pieces opened-no tile is in those cracks. Juan left the tile backsplash with streaks from the sponge. And Juan did not apply border of caulking to the edges. Juan left tile with streaks and clumps of mortal around our cabinets, on tile and on the wall. After discussing these concerns with Juan he mentioned I was criticizing his work and his integrity. Juan mentioned he has not had a dissatisfied customer who have complained about his work. I mentioned to Juan my OCD kicked in and when we hire someone to do the work the expectation is to complete the work to customers satisfaction and clean up after you have completed your task for the day! Juan mentioned he will return to ensure we are satisfied and complete the work and neither less to say I received a text from Juan stating he will return $100 off the bill that was paid to us and he does not want to work for us! Bad customer services and not acceptable for any customer Very Disappointed"

"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."

"All 6 smoke alarms in our house went off during the middle of the night, despite no indications of either smoke or fire. I was in contact with Bill Hicks first thing in the morning and he was at our house within 2 hours. He checked them all out and recommended replacing them because of their age. He disconnected all of the old ones, found suitable replacements and got the job done in a quick and professional manner. BTW, we have very high ceilings, which made this job challenging. We recommend Bill highly and will definitely consider him for future projects."

"We had two technicians out over two days. One was for a repair, Daniel. He did a fantastic job troubleshooting and explaining throughout the repair process. As a retired VP of Services, I notice the details and process. They delivered. Louis was sent for a follow-up to service because our fan motor unit needed to be cleaned. All of this was very well documented with pictures and showing me the actual motor unit. Louis did a great job of explaining and showing me the actions and results. It was a service text book delivery of services. Really good... Plus, both technicians worked to save me money with discounts and customer loyalty savings. Fantastic...

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.
