Providing HVAC service and repair, system replacement, and air conditioning solutions for older homes. Residential plumbing service, repair, emergency service, and water heaters. Electrical emergency service, repair, home upgrades, generators and EV Chargers.
"Jeff and his team did and excellent job with the installation of two Daikin HVAC units. I had many questions about the units and install and they were quick and thorough in responding. The price and warranty were competitive with high end brands. The crew was courteous and professional during the two day install. They were the only company that included replacement of the coolant lines, rather than just flushing the old ones. So far the Daikin variable speed AC units are exceptionally quiet and the house is very comfortable. Would recommend Ace Home Services and Unique Comfort without reservation."

Horizon Services is the Heating Company Your Friends and Neighbors Call to Keep Warm All Winter Long!
"I wouldn’t be writing this Review if one thing would have happened, TALK TO ME. Don’t place the answering service in the position of telling a Customer that the Supervisor has left for the day at 2.45p on a Thursday. Especially when the Horizon repairman had just fried our whole cooling system, including the thermostat!! What started with a bad fan motor in a new AC system that was only 3.5 years old in a $10,000 system, for which we had waited 4 days for the new motor to be installed. Add to that the fact that the repairman told me he would be at our home at 8.30a and didn’t arrive until 11.30a - after having to use a vacation day to wait at home for them to arrive. Then telling me this will be ‘quick’ all I have to do is switch out the motor by mounting it and plugging in the new one. Hours went by, nothing. He comes in to test the thermostat and it is non-responsive. He tells me to get new batteries, which I did. Then asks me, “these are new?” To which I say, ‘of course’ - you watched me take them out of the box. Then he goes out to his truck for the next 1.5hrs, supposedly speaks with his Supervisor and comes in and tells me that he has fried the system. I reply by saying I will be calling a senior person to speak with them. Called 4 times and never spoke with anyone. Each time I waited on hold for an extended period of time. Each time, I was then told by the answering service that someone would call and never did. Then at 2.45p I am told “everyone has left for the day” and no one would be calling. This was a Thursday, I had been home all day and no one would speak with me. We remain without an AC system, no plan, no calls - - nothing!!! If I could rate them a ZERO, I would,"

"A Raving Review for Green Mechanical LLC! If you’re looking for the absolute best HVAC service around, look no further than Green Mechanical LLC! This company is truly a gem, and I couldn’t be more thrilled with the incredible service they provided. My heater had been misdiagnosed by another company, leaving my family and me in the cold—literally! Thankfully, I called Green Mechanical LLC, and they completely turned things around. From the moment I called, I knew I was in good hands. Devin Green, the owner himself, came to my house to personally assess the issue. This level of dedication and care is something you just don’t see every day! Devin’s professionalism, deep expertise, and genuine commitment to solving the problem made all the difference. He didn’t just slap on a temporary fix or rush through the job—he made sure to thoroughly diagnose the issue and explain every step of the process to me. A huge shoutout to Jacob and G, who also worked on my system. They were punctual, knowledgeable, and incredibly respectful of my home. Their teamwork and attention to detail were top-notch, and it was clear they take immense pride in their work. Thanks to Devin, Jacob, and G, my heater is now working perfectly, and my family can finally enjoy a warm, comfortable home again! I also want to emphasize how important it is to support small businesses like Green Mechanical LLC. These are the companies that truly care about their customers and their communities. Devin and his team are local experts who go above and beyond to deliver top-notch service, and they deserve every bit of your trust and business. If you need HVAC services—whether it’s a repair, installation, or just regular maintenance—do yourself a favor and call Green Mechanical LLC. Their commitment to excellence, fair pricing, and outstanding customer service make them a company you’ll want to recommend to everyone you know. Thank you, Devin, Jacob, and G, for your amazing work and dedication. You’ve earned a lifelong customer! 🌟"

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.
