Atlas Home Energy Solutions is committed to providing the highest quality home energy improvements to homeowners interested in reducing their utility bills and improving the comfort of their home year round. Customer Satisfaction is our number one priority and we promise that we can make a real impact in your home in a way that keeps you happy every step of the way.

"Atlas home energy solutions did an outstanding job from start to finish. They were professional, knowledgeable, courteous and easy to work with. All the crew members Ben Mott (was very knowledgeable, did the home energy audit, followed up with competitive quotes, which was adjusted to accommodate my request, offered BGE rebates upfront, patient and friendly to attend my calls and answer all the questions), Zam (Crew leader who did the exhaust fan installation), Tun (Crew leader who did an outstanding job to insulate the attic and basement), David (Crew leader who did duct cleaning and Aeroseal) were phenomenal and did an outstanding job. The end result is a day and night difference before and after the work and my BGE bill last month went down by more than $100 which is a huge cost saver. The HVAC does not run that much these days and the temperature is pretty even across the 30-year townhouse. I highly recommend Atlas home energy solutions for home energy audit and improvements."

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 called to get an inspection done on my AC unit and was quoted $90 for the inspection plus $120 an hr for ADDITIONAL hrs. I ASKED when do I know when the “additional hrs start”, He stated that the tech would let me know once the inspection was done and then at that time he would let me know if there was work that needed to be fixed or if there was nothing then the service would end and I would only have to pay the $90. They charged me $210 for the inspection. I called and requested that we both listen to the call (Because all calls are recorded) They played the call, heard what the rep said and then stated they would get back to me. When I finally reached them again (they never called me back), they stated I would not get a refund, then replayed the call cutting out the part when the rep stated clearly that the service was only $90. They not only GASLIGHTED me, but they altered the recording. $120 may not matter to most but it sure matters to me."

Energy Efficiency Auditing questions, answered by experts

Typically, triple-pane windows made with krypton gas filling are the most energy efficient. A window’s frame, glass, design, and installation all affect its energy efficiency. These windows, in particular, are designed highly effectively in terms of their ability to insulate.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

There are several signs that your house might have poor ventilation, including lingering odors, condensation on your windows, or mold and mildew. Your home may also feel stale and stuffy, or you might have trouble maintaining a comfortable temperature in your home. On top of that, you might develop allergy symptoms, such as sneezing, coughing, or headaches.

It’s not recommended to turn off your breaker box in hopes of saving electricity. Breaker boxes were not designed to constantly be switched on and off. Therefore, turning off breakers unnecessarily can cause costly damage that outnumbers any energy savings. Only flip your breakers if absolutely necessary when troubleshooting an electrical issue.

While you can perform many routine home maintenance jobs yourself, it’s often a good idea to bring pros in for certain tasks. HVAC maintenance, fireplace and chimney inspections, foundation repairs, and roof inspections and repairs should be handled by professionals who know what to look for and can safely perform repairs. You may also find it helpful to hire a local house cleaning service to help with deep cleaning.
