"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"

"2 of 997 Urgent: Project Management Issues & Pending Renovation Work We are experiencing significant project management issues that have caused unnecessary delays and frustration.Their quality of work is good but project management sucks big time,. We started our bathroom rennovations on Nov 29th 2024 the project wsda supposed to be completed in 5 weeks now it is almost 2 months and the master bathroom still needs to begin constreuction. We have had 3 project managers so far. However, despite multiple follow-ups over the past week via our text messaging group and several calls, we have yet to receive any updates on a variety of outstanding work in the loft and guest bathroom that need to be done. This lack of communication and progress is unacceptable. While we understand that Elkay is taking a break, the responsibility for keeping us informed and ensuring the project stays on track should not be neglected. We are not getting proper updates about stataus of several pending issues and we feel like we are being passed around without any clear resolution or accountability. The most pressing concern is the arrival of the bathtub, as all further work on the master bathroom is stalled until it arrives."

Glenmont Heating & A/C
Glenmont Heating & A/C
When Glenmont Heating & Air Conditioning was founded 28 years ago, we had one goal in mind; providing area families, and businesses with solutions that fit their lifestyles and needs, as well as their wallets. If you have any questions about heating and air conditioning maintenance, a new HVAC system, or are looking into installing a more energy efficient system, Glenmont Heating and Air is the solution to your needs.
"Not Recommended for Thermostat Replacement — Unreasonable and Unfair $700 Charge I do not recommend Glenmont Air Conditioning & Heating for thermostat replacement work. I was charged $700 for a simple thermostat replacement, which I believe was unreasonably high and unfair. I was under the impression that the quoted estimate represented the maximum expected cost only if the technician had to perform additional wiring or complex installation work. If you want to install an Ecobee or any other type of thermostat, you can simply YouTube the installation, which provides step-by-step instructions on how to unwire, label, and rewire to the new thermostat. For my installation, I was under the impression that additional wiring might be needed, but it turned out to be a straightforward swap of the old thermostat with a new Ecobee unit, a process that took only about 15 minutes. Despite that, I was still charged the full amount. The Ecobee Premium thermostat itself costs around $250, meaning they charged nearly $500 just for labor, regardless of how simple or quick the installation is. To make matters worse, the installation only comes with a 30-day warranty, which hardly justifies such a high price. I tried to communicate and explain that this charge was unreasonably high and unfair, but they simply said, “It is what it is.” If you’re considering a thermostat installation, I strongly suggest hiring a professional through Thumbtack, where qualified experts can do the same job for under $150 with transparent pricing and good service. I expected fairness, honesty, and reasonable pricing from Glenmont, but unfortunately, that was not my experience."
