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."

You and your family deserve to receive the best care and the best service. Not every heating & A/C company gives you the quality people and care that Presidential does. We offer 40 Years of Award-Winning Quality People, Quality Installation, and Quality Service. Delivering this quality service and care for your home is our commitment to you! Family-owned and operated, Presidential specializes in residential and light commercial service and installation throughout MD, VA & DC. Ask us about our system replacement specials and The Advantage Maintenance Plan for preferred VIP service. Presidential has been awarded the Carrier Factory Authorized Dealer Award and is a member of the ACCA (Air Conditioning Contractors of America) and the Quality One service network.

"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!"

"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!"

"Horrible company, horrible service, still waiting after 14 days for an update. Claimed they ordered part, then found out they didn’t order the part, then they schedule an appointment and didn’t show up. Dispatch was rude and they didn’t return calls and messages. Same company misdiagnosed my mom’s HVAC system and she ended up getting it replaced only to find it still kept shutting off because it was a gas regulator that was the problem all along."

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."

ABV provides same-day repair services and right the first time. All you need is to call our specialist on the website or by phone. We guarantee high-level services as well as 90 days parts warranty and 90 days labor warranty. We are a local, family-owned, and operated company with more than 10 years of experience in the appliance repair industry. ABV service is focused on excellent customer service and care because our customer's satisfaction is our main priority.

"While ABV was able to eventually repair my GE Profile counter depth refrigerator, it took a long time with a lot of trial and error, and was extremely expensive. It seems like the tech didn't know what he was doing, and diagnosed repairs that didn't need to be made. First, the tech diagnosed the problem as a bad control panel, which cost $2,400 to replace. That didn't fix the problem. Next, the tech guessed that the problem was the compressor control board and replaced that. To ABV's credit, they didn't charge me for the control board when that didn't turn out to be the problem. Finally, they decided that the compressor needed to be replaced, which cost $1800. That fixed the issue. Three simultaneous systems failures is highly improbable, and I strongly suspect that if the compressor had been replaced first, I would have avoided spending an additional $2400. I should have gone with GE's repair service first, but no availability for 2 weeks. ABV took 3.5 weeks to finally repair."

Humidifier Repair questions, answered by experts

During your HVAC preseason maintenance call, your contractor will inspect the system for any problems and make small adjustments for better efficiency. Tasks include, though are not limited to: 

  • Changing filters

  • Checking the thermostat

  • Clearing away dust and debris

  • Checking for mold

  • Inspecting electrical elements

  • Inspecting condensate lines and drain

  • Cleaning evaporator coils

  • Ensuring ignition function

While you can do some of these services yourself, hiring a professional to keep HVAC equipment running can be helpful. These experts know what to look for and may be able to spot potential issues before they become problems. Many HVAC companies offer annual maintenance plans.

NATE-certified technicians may charge slightly higher service fees compared to non-certified technicians. This is because NATE certification signifies a higher level of expertise and professionalism, often leading to more efficient and effective HVAC repairs and installations. While the upfront cost may be marginally higher, NATE-certified technicians can potentially save you money in the long run by reducing energy consumption, preventing frequent breakdowns, and extending the life span of your HVAC system. When looking for a local HVAC company to hire, it never hurts to ask about NATE certifications.

The life expectancy of a humidifier is around ten years on average, but this can vary depending on factors such as usage, maintenance, and the quality of the unit. To help your humidifier last as long as possible, it's important to regularly follow the manufacturer's instructions for cleaning and maintenance.

Whole-house humidifiers can damage your furnace if a problem with the water supply happens. To avoid mechanical trouble, maintain your humidifier by keeping the filter clean and the drain line clear.

NATE (North American Technician Excellence) certification is not legally required for HVAC technicians in most areas, but hiring a professional with this certification is highly recommended. NATE-certified technicians demonstrated their expertise and proficiency in different types of HVAC systems, offering assurance of quality service. It's a voluntary certification, yet it indicates a commitment to professionalism and ongoing training. Choosing a NATE-certified technician often means you're working with someone who is up-to-date on industry standards and best practices, which can lead to better service, energy efficiency, and long-term cost savings.
