It’s our attention to service and quality, Each appointment made with one of our clients is set up by one of our experienced electricians.

"Job was to install EV charger in garage and rewire garage so garage doors and garage lights can be independently operated from inside the house and install several sockets in the house and garage. Honest, pleasant, capable, good problem solvers, competent electricians (passed county inspection for panel work and charger in a breeze. Added extra work at reasonable cost. Charged the market price for the charger (others tried to gouge, as if it was an unusual request). Hit my price target while others missed wildly (half of where the highest bid came). Otherwise, was competitive in the market. Responded to my specific requirements rather than vague "other work" category. Performed the tasks in a workmanlike manner and were pleasant and easy to work with. DC metro area is unusual in that a contractor can come from DC, Maryland or Virginia, so being confident of insurance, licensing, etc is important - "

"They charged $98 to come give me an estimate for swapping our a shower valve cartridge, which was fine, but the pricing they provided was completely unreasonable, $1,000. They were unwilling to provide any detail for the price. I ended up buy the part myself for $30 and replaced it in 30 minutes."

"This dude shows up on time, 5/5 on that. Leaves 10 minutes later without saying a word. I message him 3 hours later asking if we were still doing the job. 2 hours after that he messaged back saying he had his helpers cancel and we need to reschedule. I ask when he's thinking we can get it done. 3 days later I haven't heard back. I open a new project on Angi, and re-select this same guy by mistake. He replies promptly, gets all the details, and then once he gets my email no further contact. It feels like there's something personal here, or maybe he quoted too low for the project, but in any case I literally cannot imagine a less professional way of handling this whole situation. My guess is that he showed up to the job to scope it out, then went to find a couple day laborers to actually do the work. Maybe he couldn't find any, maybe he realized that this job was too big. In either case, just say so. Jesus."

FAQs for thermostat installation and replacement projects in Triangle, VA

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.
