At Green Mechanical, we pride ourselves in being honest and transparent. Our focus is honesty, quality and integrity. We personally take the time to make sure you are 100% happy with our services!

"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! 🌟"

"Just like some the other comments….Extremely unprofessional customer service person who answers the phone, interrupted several times and hung up on me. If you have a problem with their work won’t help you. Even when I inquired about warranty of their work I got a rude attitude.DO NOT RECOMMEND"

"Worst service I’ve ever have experienced. They wanted to sell me the product, never told me that there was an early termination fee and another penalty for an initial offer they gave me. Had double charges every month, once for the oil they provided (which they never told me they were going to provide before coming. They just came without my knowledge and then I find a high amount bill) and another for an “automatic payment” for 500 that they never could explain. The didn’t even fix this issue and it kept happening every month even after I cancelled the service. Then having to call them is a hastié for the refund of the 500. Stay away of this company"

So, why choose K-Wood, LLC, for your HVAC needs? The reason is we are fanatics about doing the job right. Not only do we choose the best equipment, we choose the best equipment for the job. We will also size the unit to your house. We take into account insulation, windows, and even the positioning of your house relative to the sun. We do this because a poorly sized unit is not good for anyone. If it is an air conditioner and it is too small, it will be running too much. This will increase your power bill and decrease the unit's life. If it is too large, the unit will short cycle (or turn on and off too quickly), which will also decrease the units life span. In the summer this short cycling won't allow for the humidity to be removed properly. The best equipment costs more up front, and a proper installation is not cheap either, but when you pay for both of these up front, you will have fewer problems and save a significant amount of money compared to the cheaper guy.

Boiler Repair questions, answered by experts

A furnace takes in cool air, heats it through the burner and heat exchanger, and sends the air on its way to warm your home. A boiler is a pressurized vessel that produces hot water or steam to heat the home and provide hot water. A boiler may or may not work together with a furnace.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

If you have a closed-system boiler that needs an expansion tank to work, you cannot run your boiler without it (not without the risk of extensive damage and even explosions). Your options include moving the boiler to another spot, rerouting boiler piping to a more open area, or completing a remodel around the boiler to create more space for the tank.

Attempting DIY fixes can be dangerous. Regular boiler maintenance can help prevent overheating, so schedule professional servicing as a preventive measure. In an emergency, telling occupants to leave the house is a good idea. Then, you can turn off the boiler and the gas or fuel supply. Let it cool naturally, and check the thermostat's settings. Ensure there are no obstructions around the boiler for proper ventilation. Monitor the pressure gauge; if it's too high, bleed the radiators if necessary. During this time, bringing in professionals for troubleshooting is also smart.

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.

By submitting this question, I acknowledge and agree that Angi may publicly display my name, city, state, and question on the website for professionals and others to see.
