He was punctual, professional and honest. I had done a preliminary inspection and could not assess what was wrong as the air conditioner consistently blew the electrical fuse. He assessed the situation and was able to confirm the capacitor needed to be replaced. The part was not a common one in stock, but he was able to order it and expedite to get in the following day. He inspected the other air conditioner and confirmed it was working well and did not need additional service. He was able to correct an incorrectly installed drain valve to allow proper draining which had caused some issues in the past. He was out the next day to install the parts and noted that the air conditioner needed to be charged. The cost estimate was accurate and he took the time to explain the issue and spent time needed to confirm no other issues were encountered. He also installed a programmable thermometer which centrally controls the AC and heat at a very cost competitive level. I reviewed their write-up in Angie's list which is how I called them for Service. AC service can have suspect service providers, but the write-up was spot on. PCK is friendly, prompt, reliable and honest! I will use them for all my AC servicing needs and I would recommend them to others without hesitation or reservation.

We needed an HVAC specialist for our 6 unit apartment building, and he came highly recommended by my realtor. He is arrogant, but he always returned my calls and showed up to the job site on time. I used him because he would come at all hours of the day, and this made my tenants happy. He installed two new HVAC units for the apartment. You would think that since the HVAC is new, it should not have issues for at least a few years - I was wrong. There were problems starting just a few months after installation and I continued to have problems until I hired a REAL HVAC specialst. The new and real HVAC specialist said that Oscar did a shoddy job installing the HVAC units. The drain pipes were not glued, line caps were missing and the unit was not draining properly. There were freon leaks on the outside unit. He also installed thermostats for two units which was a BIG nightmare. For one unit, he had to come back every spring and every fall because the AC/Heat wasn't working. He would snip wires and reconnect the wires, saying that the HVAC unit is to blame because it is so old. According to the new HVAC tech, Oscar installed the WRONG thermostat, so he would come over in the spring to connect the AC wire to the thermostat. In the fall, he would connect the heating wires to the thermostat. What a waste of money! The biggest waste of money was in another unit where the tenant's electrical bill was super high (about $400-$500 per month for an apartment unit). I called him repeatedly, but his answer was always "it's the tenants' fault. He's cranking up the heat too high." After a few months of high heating bills, the tenant finally moved out. The same thing happened to the next tenant, and I lost her too. Our new HVAC tech found out what was wrong. When Oscar installed the new thermostat, he inserted both the heating wire and AC wire in the same slot, so the heating and cooling were going on at the same time. To make things worse, he installed the wires in the emergency heat slot in the thermostat, hence the high electrical bill. After a few of these mishaps, we fired him.

"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."

"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!"

BlueStar Air Mechanical is a call away for your repair, maintenance and installation needs. We specialize in fixing and tuning up cooling, heating and plumbing systems for both residential homes and commercial establishments.
"I contacted Bluestar Air Mechanical for a second opinion after an appointment with Air One. I have a Carrier HVAC system, and the Air One technician recommended a complete system replacement, claiming the blower was bad, the furnace control board needed replacing, and that there were other issues. Since replacing the HVAC is a big investment, I wanted to get a second opinion. It was only after comparing the service from Bluestar that I realized Air One may have been pushing for a new system sale or lacked the expertise to properly diagnose and repair the actual problems. Isaac, the technician from Bluestar, spent about an hour thoroughly diagnosing and fixing the issues. He found burnt wiring in the furnace and discovered that the wrong capacitor had been incorrectly installed in the AC. Isaac replaced the burnt wiring in the furnace and the capacitor in the AC. After these repairs, my Carrier system was back up and running—without the need for a costly replacement. Bluestar, and Isaac in particular, demonstrated professionalism, expertise, and honesty. They focused on resolving the actual issues instead of pushing for an unnecessary system replacement. I highly recommend Bluestar for their reliable service and Isaac’s thorough and knowledgeable work."

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."

FAQs for heating and air conditioning service projects in Olney, MD
Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.
While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.
The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.
Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
