We have over 10 years of experience in the business. Here at Hamilton Electric we pride our company on reliability, great communication, integrity, and quality work. We are experts in our trade and will do our best to keep you as educated as we can on your particular task or project. We look forward to earning your business!

"We had a great experience with Ryan Hamilton Electric when they came to work on our building and in our apartment. We had discovered that the knob and tube wiring that we thought had been removed from our apartment was still present, and so we hired Ryan to remove the old type of wiring and bring our unit up to code. Ryan and his assistant Tim went above and beyond when it came to doing the work. Ryan explained very clearly to us exactly what the issues were with the knob and tube wiring and showed us exactly what had to be done to fix the problem. We had no surprises. While we were hiring Ryan to remove the old wiring, we also asked him about doing some other electrical work in our apartment. Ryan was happy to add on these further improvements and charge us only for the materials since we were already paying for the labor. Ryan listened to our desire for improved lighting and better outlets, and he presented solutions that would work for us and our kids. He found the perfect lighting fixtures for all the bedrooms and the bathroom, and he offered to improve lighting when it seemed necessary. The project took a few days; Ryan made sure we had the temporary lighting we would need in the evenings after he had completed work for the day. Ryan and Tim also cleaned up beautifully each afternoon when they were done with their work. Ryan and Tim didn't just do exemplary work. They were also warm, friendly, and affable, and a delight to have working in our apartment. We will actually miss having them around, but we were so impressed and delighted by their work that we plan to hire them again soon to improve the lighting in the kitchen and to install new outlets in the bedrooms. R. A. Hamilton Electric has my highest recommendation. I am a very happy and satisfied homeowner."

"they initially quoted $89 for AC diagnostics which is reasonable even though most companies charge nothing. Technician is very friendly and knowledgeable and walked me through the process. he checked the compressor outside and he suspected a leak. and then wanted to check the coil inside the blower. he detected a small leak with the electronic device. he mentioned coil may need replacement. After spending 10 mins in his truck to call the company he came back and said coil is not covered with warranty and quoted $5,400 to replace the coil and it is backordered for 6 weeks. 6 week will brings us to mid August so i told him i dont want to sign up for repair and wait 6 weeks. he then tried to sell me a maintenance plan which i declined. Then he said he will charge for the diagnostics which he spent total 30 mins including talking on the phone for warranty coverage. he said he did more than basic diagnostics which is $149. when he handed me the payment he added up initial $89 and $149 to pay $238 for 30 mins diagnostics. Total scam. i dont even know if they do any real work beyond the charging $238 for 30 mins diagnostics. probably they will hire a separate contractor to do the job and keep selling overpriced diagnostics and maintenance plans. They all you 10 times to sell you the initial diagnostics but after you pay $238 not even a single call to ask about experience. worst ever."

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.
