Get matched with top window a/c unit installers in Wallingford, PA

"Overestimated the time to complete an 9 hr job by scheduling a 16 hr window (2 guys x 8 hrs) and charged for 16 hrs regardless. I'd imagine they did the same for the materials, 60 feet of duct needed but they quoted 200. Got the job done, but probably twice the price of what it should have been."

"Crew was professional and they did a great job."

"Less than 5 years ago, I spent in excess of $10,000 to have a new unit installed with a 10 year warranty. I should have seen the red flags from the very beginning. The sales representative told us additional vents would be installed and when the installation crew showed up, that did not happen. Fast forward to the present and I am now on my 4th phone call for an appointment this season, 3 days so far of not being able to work as I waited for a technician to come diagnose the problem. The 3rd. tech came last night and indicated that the work the other tech did was not for the root of the problem. (I was told in front of witnesses that the work needed to be done, was not covered under warranty, would cost me $367 and would fix my issues)In fact, the 3rd tech only made the issue worse by leaving our attic return unscrewed and overfilling our unit with Freon that the 4th tech had to remove from our system. Upon leaving last night I was told that everything was corrected. Today - my home is slowly creeping up in temperature (presently 80 degrees inside, while set to 72). The company keeps trying to sell me a "maintenance plan" and I keep reiterating to EVERY one who pushes it that we have been getting tune ups/cleanings elsewhere and will only use them for warranty issues since we have had NOTHING but problems with them."

"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! 🌟"

"Our experience with Finishing Touches was positive from beginning to end. They are Incredibly skilled/professional, transparent, with honesty and fair pricing, great attention for detail and pride in their work!! Steve responded promptly to our inquiry. He gave us a free estimate that ended up being very open and accurate till the end. They helped us with painting several rooms, ceiling fan installations, electrical outlet repair, custom drywall in closets with built shelving, and a custom door we asked for knowing the difficulty it might present with the age of our house. They transformed every space they worked on. Steve and John took the time to look at the job thoroughly to help us put together a plan for a scope of work we could perform and afford within our budget. They answered all questions we had along the way without hesitation! They took the time to complete all aspects of the job with skill and care for my property while still having a good turn around time all in. We are extremely satisfied with our choice in Finishing Touches. We would hire them again without question!!"

"though I appreciate the emergency Saturday service call (cost 169.00), I thought the additional charge of 303.00 (450.00) for a diagnostic check and repair ( no parts necessary - just less than a hour of manpower) was a bit exorbitant. perhaps I failed to realize that heating/ac personnel are paid on the equivalent scale as neurosurgeons."

"Gen 3 came out, gave us a couple options to choose from, and performed the needed maintenance. Went smoothly. Thanks!"

"They were professional, and they did a very well job."

"Fantastic. Jonathan knows what he’s doing, very precise with measurements, and has a wide range of abilities. So friendly and personable. He helped transform our new build house into a finished home. He is able to install many things, curtain rods, ceiling shower rods, heavy mirrors, heavy art work, and now is tackling adding wire rack shelves in our closets. Next up some Ikea cabinets in our laundry, and painting our garage. His prices are up front and very reasonable. He is licensed and insured. We feel he is quite a gem to have found! Would not hesitate to hire him again and again. He is very positive, eager to work and does excellent work."
