"The technician (Shammion) arrived on time and spent time listening to my concerns and answered my questions before proceeding with the work. Shammion has serviced my furnace and a/c unit previously, and on each occasion he has spent time informing me how various parts of my HVAC should work and what I need to do to get the most from the systems. On this occasion, Shammion instructed me on how to use my new thermostat and how best to keep my condenser coil clean in the future. The work was done expertly and in a professional manner, and I highly recommend Shammion and McCrea Heating and Air Conditioning."

"Quickly diagnosed the central air conditioning system, and gave an estimate on the cost of recharging the refrigerant in the compressor. The system is a 14 year old Carrier unit. Albert also included some sealant that may plug up the slow leak of refrigerant that occurs every 2 years or so. Albert also, showed me how to adjust the damper to control the flow of air to the second and third floors of the house. The other company that arrived wanted to charge me $5,000 to repair the system or close to $7,000 to replace the AC system with new. I intend to call upon Magna Tech Temp Air, Inc when I'm ready to purchase a new HVAC system. Thanks again for taking the time to listen to my concerns. Well done!!!"

"TC HVAC showed up on time, were professional, did what they said they would do at the price they quoted (which was better than any other company) and the system is working wonderful. I will use them again when we are ready to replace our water heater and A/C unit."

"I do not know how anyone could rate this company less than 5 stars. Terrone came to my property the day after I posted on Home Advisor and advised me that my system was pretty much a complete loss, dangerous and needed to be replaced. I already knew he was right. Within in 2 days he had a crew at the property to replace the entire HVAC system. During the replacement process they corrected two every significant problems that existed with the old system. First, the air filter couldn't be changed because the return was jammed in behind a water tank, that made it extremely difficult to change, which it hadn't been in a very long time. They installed a return vent that allows the filter to be changed from the living room, which was really great. They also found that there was an emergency shut off for the furnace, but it was behind the unit and could not be reached. They moved, replaced and marked the new value so that it was easy to see and easy to use if needed. The system is in an awkward place and his crew was able to remove the old system and but in the new system without having to remove a wall, which I thought they would have to do. Their work was great, well done and significantly less expensive than what others had quoted me. Like I said in the beginning, I don't know how anyone could rate this company less than 5 stars. If I have any more HVAC issues, Terrone will be the first person I call."

"This was for semiannual maintenance under contract. Danny performed an excellent job, he has many years of experience. I have used ARS for the heating/air conditioning maintenance for about 35 years. They replaced the equipment about six years ago. It has not failed since replacement."

"

we had a leak problem and the tech came and looked over our equipment, fixed the problem and left. It cost us nothing and we have had their home heating service contracts for over 20 years.  They have NEVER ONCE not shown up or not helped and in the two furnace emergencies we had--they were here with in 1hr. 

We are very happy.

"They were the HVAC sub on our total house remodeling due to a house fire. We decided to add central air because the walls and ceilings were open and we at the time had window units. They installed a heat pump with a Nest thermostat. In addition to the heat pump the house had an existing radiator heating system. However, the hot water heater, boiler, and water line were damaged or clogged due to the fire. T & J replaced everything and were extremely polite and explained everything as well as how to do simple repairs. I would recommend them to my friends and will definitely be using them for annual maintenance."

FAQs for air conditioning projects in Dale City, VA

Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.

Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.

Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.

Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.

Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
