Pro Sky Services, Inc. is committed to excellence in every aspect of our business. We uphold a standard of integrity bound by fairness, honesty, and personal responsibility. Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade combined with ability is what makes us true professionals. Above all, we are watchful of our customers' interests, and make their concerns the basis of our business.

"2/3/2021 - Glad to have found Pro Sky Wow, what a great experience I just had with Pro Sky! Our heat pump went out during an impending snowstorm. Two companies on Thumbtack were quick to respond. Pro Sky got the nod because they could dispatch a technician immediately. It mattered when our house was getting so cold so fast. It also helped that Frank explained clearly his companyâ s approach in his initial response. As soon as I confirmed the appointment with Frank, I received a text giving an ETA for technician William to come by. Oh, another thing I like about Pro Sky is they use the Housecall Pro platform to send me appointment info, estimates, and receipts. All were super clear, and the platform was so convenient. Back to William, he arrived promptly wearing a mask and minding his distance. He listened patiently to the long history of issues weâ ve had with our Carrier Infinity thermostat before setting out to run the diagnostic tests on our heat pump. The tests confirmed the system was in good shape, the problem was with the thermostat. William took the time to explain our options for a thermostat replacement and addressed all of our questions and concerns without trying to sell us any particular product (or service for that matter). That is how you earn trust and respect from your potential (and repeated) customers. We would like to rewire our full system to use a third-party thermostat, and we will request William for the job. Thanks Pro Sky! 8/18/2021 - A happy customer is a repeat customer Last week was my fourth service call to Pro Sky: (1) system rewired & thermostat replacement, (2) water heater replacement, (3) HVAC Spring services, and (4) A/C start capacitor replacement. Our A/C stopped blowing cold air on a near-100-degree day last week. Who you gonna call? Of course, I called Pro Sky. Frank reassured me he would always have availability for a loyal customer. A different technician this time, the process was the same. I received a text with a link to Housecallproâ s job description, arrival window, and estimate ($45 for a diagnosis visit). Santo arrived on time, made a quick diagnose (bad capacitor), provided a reasonable price quote for a replacement which we agreed to. He replaced the dual capacitor, did a health check of our A/C system and was done in about 30 minutes. Super efficient! The service fee was waived in our final bill. Our A/C has been running fine ever since. Thanks again, Pro Sky!"

MASTER HVAC License We take great pride in offering the best possible experience with our expertise, quality, and customer service.

It is our mission to exceed our clients expectations by providing excellent workmanship and complete customer satisfaction, from the start of each project to its completion. Our reputation is based on service, safety, and quality, regardless of how large or small the job.

"We had an absolutely fantastic experience with X&M Heating and Cooling! From start to finish, Richard was beyond responsive, professional, and genuinely a pleasure to work with. You don’t always expect replacing major home systems to feel stress-free, but Richard made the whole process smooth and even enjoyable. They replaced our AC/Furnace (Condenser, Coil Pack, and Heater) as well as our hot water tank—a big job—and the crew knocked it out of the park. Everything was installed with care, attention to detail, and a clear pride in their workmanship. Richard took the time to explain what was happening every step of the way, which gave us total peace of mind. What stood out most, though, was the responsiveness. Whenever I had a question, Richard was quick to answer, patient, and genuinely friendly—it felt like working with a trusted neighbor rather than just a contractor. If you’re looking for a team that does top-notch work - don't look any further."

"The APR21 initial HVAC installation was successful, and the heat pump worked fine during the cooler months. However, when summer arrived the condenser unit in the basement leaked, and the water damaged the basement carpet. The dominion service man discovered that the air filter (20x16) had NOT been installed during the initial HVAC installation, and based on his many years of experience that caused the overflow. Dominion still charged me for the visit, claiming that the new drain was clogged Mind you, this was an entirely new HVAC installation, and a clogged drain after 8 weeks of AC operation is not likely - except when the filter is not installed. This was my experience with Dominion Service Company."

FAQs for air conditioning projects in Ashburn, VA

You can identify your system's refrigerant type by examining the data plate or label often located on the outdoor condensing unit. Look for "R-22" or "HCFC-22" in the specifications. 

Manufacturing date provides another clue—systems produced before 2010 often use R-22, while newer units utilize alternative refrigerants. If the label is missing or unclear, a qualified HVAC technician can determine your refrigerant type during a service inspection.

Federal regulations prohibit the purchase and handling of R-22 refrigerant without proper EPA certification. These restrictions exist because R-22 contributes to ozone depletion when released into the atmosphere and requires specialized handling procedures. 

Additionally, improper refrigerant charging can damage your system and create safety hazards. Professional technicians have the training, equipment, and legal authorization to properly diagnose, repair, and recharge your system.

Air conditioning systems require approximately two to four pounds of R-22 per ton of cooling capacity, with three pounds per ton being the average. For example, a 3-ton system needs about nine pounds of refrigerant for a complete charge. However, the exact amount varies by manufacturer, model, and system configuration. A professional technician will determine the precise charge required for your specific equipment.

While technically possible to retrofit some R-22 systems to use alternative refrigerants, these conversions require substantial modifications to system components and are rarely cost-effective. The compressor, expansion valve, and sometimes the entire coil system would need replacement or adaptation. Most homeowners find that investing in a complete system upgrade provides better long-term value and performance than attempting conversion of aging equipment.

Though new production of R-22 ended in 2020, reclaimed and recycled supplies remain available but are steadily decreasing. The EPA's final phaseout deadline extends to 2030, but practical availability may become severely limited well before that date. As supplies continue to diminish, expect prices to rise accordingly. Homeowners with R-22 systems should begin planning for eventual system replacement as part of their long-term home maintenance strategy.
