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."

"They installed our AC system; that went fine. But several years later, when it needed repair. They came out and looked at the problem, and then ghosted me. They didn't return my multiple calls. When I finally got somebody else to come out to look at the problem, they told me that the warranty had just expired on the part that needed replacing. Putting 2 +2 together, Buric ghosted me to run out the clock on my warranty for the repair of the product they installed. Would you ever hire anybody who behaves like that???"

Beltway Air Conditioning & Heating is locally owned & operated out of Hanover, MD. We are Lennox Premier Dealers & are BBB accredited with A+ ratings & reviews - We provide services & installations within a 50 mile radius of home base. Our team specializes in installing and servicing heating, cooling & ventilation equipment, whether it is a small A/C repair or a commercial rooftop - our team is trained to take care of all your HVAC needs! We bring extensive experience and professionalism to every home and commercial building. Our work reflects our passion! The Best Price + The Best Work = Your Best Value. We have uniformed & well-trained staff that under goes background checks and drug screening upon hire and randomly. All of our service professionals are also licensed to work in the state of Maryland.
"We are a bit disappointed by Beltway. While we do appreciate some of their efforts in trying to remedy the situation, the overall experience has been quite negative. Please see reasons below: 1. A brand new HVAC system that was installed on Wednesday completely failed by Saturday morning - which was less than 3 days of installation. This calls into question the quality of Beltway’s product or job, or both. 2. Weekend messenger centers have been extremely frustrating and unhelpful, basically saying that Beltway does not serve customers during non-business hours and that customers just have to deal with Beltway’s issues on their own. We called 4 times this weekend out of desperation. Yet each time they showed no sympathy on the fact that our baby has been suffering through the 80 to 90-degree heat trying to nap. 3. A weekend technician was finally sent on late Sunday afternoon (thanks to owner’s stepping in); however his timing messed up weekend plan as one of us had to stay home and completely missed our good friend’s son’s high school graduation party (now people at the party learned about Beltway…). 4. Unfortunately, this weekend technical was unable to solve the problem and decided to leave us with 2 portable cooling units, which, unfortunately, were extremely loud and inefficient in cooling down, so most of us weren’t able to sleep, just like the night before. Felt like all of their products that we’ve coped with in the past 5 days have been nothing but disappointing. 5. Finally, the full crew came on Monday. But their timing here again messed up the baby’s nap schedule - as the upstairs system was right next to the nursery. This is our first time hiring Beltway. The amount of inconvenience and frustration that they had created in the past 3 days was unbelievable. The experience has been quite negative from multiple aspects, calling into question not only their customer service ability/arrangement but also quality of their products and jobs. We don’t know if we can trust Beltway again or hire them again."

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."

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.
The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
