Get matched with top central vacuum system service pros in Dickerson, MD

"Excellent service! I had a 26yr old A/C and Propane furnace that I wanted to update to an ALL ELECTRIC high efficiency heat pump. The price in the estimate was much higher than I was expecting, but they worked with me and brought it down considerably, provided I could accept an install slot in a couple of days due to a cancellation. Go for it, I thought! Unfortunately, it turned out that the estimator/salesman (who shall remain nameless) apparently got a bit confused and set up the equipment as a hybrid propane system - not the all-electric system that I wanted. Ugh. I only realized this when the installers had the indoor unit in place, and I saw the propane burners. Doh! So, I explained the situation to them, and they pulled the unwanted unit out and jumped through the hoops to order the correct unit and its accessories (wiring, breakers etc.), with no change to the price. They were very friendly and polite through all of this even though it meant the wasted work and that they had to come back the next day with the new IDU. Anyway, the final install all went well, and they were very friendly and respectful of the property and explained all the install details as they went (sorry Melvin, for all the pestering!) I'm very happy with the company and the installer's knowledge and professionalism. RECOMMENDED!"

"Highly professional, knowledgeable and well behaved technician. Prices offered were good too. I definitely recommend the company."

"Edmond responded right away and listened to my explanation of the issue over the phone. It was Friday afternoon and we both agreed the issue was non-urgent so we scheduled an early Monday morning visit. He showed up at 8a sharp as we agreed and he did a thorough check of our AC system. Edmond is very knowledgeable and he explained everything thoroughly. He gave me a couple of suggestions. I’m pretty handy so I’ll try to tackle it myself. He said to just call him if I get stuck and he could either come back out or coach me over the phone. Pricing is reasonable and quality of service is top-notch. I’ll keep them on speed dial and I highly recommend Hecomo for HVAC service!"

"They charged $98 to come give me an estimate for swapping our a shower valve cartridge, which was fine, but the pricing they provided was completely unreasonable, $1,000. They were unwilling to provide any detail for the price. I ended up buy the part myself for $30 and replaced it in 30 minutes."

"Nice, reliable, and responded immediately."

"work was professional and efficient"

"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."

"They did everything phenomenally"

"Luckily they were available the next day and they did an excellent and professional job and also shared with me what they were doing and what had caused my problem."

"We signed up for a forced hot air duct cleaning job for a fixed “bargain” price of $375. Russell and David (nice guys) showed up right on time and cleaned the air ducts. We were then informed that during the work a significant amount of mold had been found in our air duct system. This was documented by several photos on Russell’s smart phone. Russell thought the conditions found amounted to about 7 out of 10 on a scale of mold severity. We were then presented with a proposal for mold remediation at a cost of $2,400. Concerned, we said we would consider the offer and sent them on their way. Next morning “Jim” (from our heating contractor) arrived for our scheduled checkup. We explained the mold issue to Jim who thought that condition to be highly unlikely. Jim “opened” the air duct system in several places. We saw only tiny hints of mold, nothing which resembled Russel’s photos or would require remediation. Our son knows of a person in the heating business who thinks that the conditions “found” are unlikely and further suggested that, if the mold was that bad, the air ducts would need to be replaced rather than remediated. I Googled “duct cleaning scams” and found that mold discovery accompanied by unnecessary proposed expensive remediation projects are quite common. Reading reviews of All-Start Duct Cleaning on Angie’s List revealed that mold had been found in several of those cases. We decided not to accept the proposed mold remediation project."
