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."

"I have used Grove for many years, and even had them replace on of my failing units. Within the past 18 months, our secondary unit started having problems and Grove came out multiple times to service the unit, explaining that it was losing refrigerant and needed to be replaced. They were always very quick to provide an estimate to replace the unit after charging it. Before replacing the unit we had a different vendor come to give a second opinion, to ensure we were informed and I am so happy that we did. We found that the unit wasn’t only running out of refrigerant, but that it was massively overcharged and that the overpressure safeties had been defeated. I’m not sure if Grove was simply negligent or if they were trying to trick us into paying for a replacement, but I can say that I won’t be using them again. The unit they replaced for us is already dead, and they are quoting us an additional $2k to repair it, putting the total cost for the unit at nearly $10k. All said I have probably paid Grove thousands of dollars and it’s impossible to tell what of that was legitimate and what of it was them running up the bill. I can tell you that at one point they made an emergency visit late at night, spent 15 minutes looking at, and cleaning my compressors, charged me $1000, and then proceeded to text me pictures of them on vacation, presumably enjoying spending the money I had paid them. While I really like Grove, I would suggest you get a second opinion regarding whatever they tell you and that you check your bill very thoroughly."

Humidifier Repair questions, answered by experts

A whole-home humidifier can help alleviate allergies by maintaining optimal humidity levels. Dry air aggravates nasal passages and can worsen allergy symptoms. Properly humidified air can soothe irritated sinuses, reducing the impact of allergens like dust mites and pollen, potentially providing relief for allergy sufferers.

It improves air quality, prevents dry skin, protects wood furniture, and enhances overall comfort.

While you’re busy swapping out that old compressor, now is a great time to have your furnace cleaned and serviced , especially if your home is older and your heating system is as old as your AC unit. Likewise, it’s a good idea to clean your air ducts to ensure air flows properly through the house.

Ideal humidity conditions generally range from 30% to 50%, with 45% considered optimal humidity for most homes. If your humidity levels drop below that range, you can turn your dehumidifier off. Additionally, suppose the temperature where the dehumidifier is installed falls below 60 degrees Fahrenheit. In that case, it's best to turn it off and unplug it since cooler temperatures can cause the unit's coils to freeze.

Whether you’re facing significant humidifier repair costs or it’s time to replace your humidifier altogether, it’s understandable to question whether the expense is worth it. Still, there are many benefits of whole-house humidifiers that you might miss, including improved indoor comfort, improved breathing and sleep, better hair and skin, and even increased home value. Either way, the answer is subjective, so it’s helpful to evaluate your home’s humidity without the unit running and give it a few weeks to see if you notice a difference.
