"Woke up with the house well above the set temperature. A/C running but no hot air coming out. Put job on Angi at 0830 and got immediately called by SwiftPro. They were the first to call and they had the highest rating of the four that were chosen by Angi. Tech arrived a little after 1100 and quickly figured out what was the problem. Tech identified one part that was the issue and another part that could cause a problem down the road. Tech didn't push the second part but the part wasn't much more so changed out both. Tech did a full inspection of the cooling system without any 'additional' issues. Up and running by 1230."

"I couldn't be happier with the outcome of having Kingdom Air do the gas furnace and air conditioning at my home. Their customer service is beyond outstanding. Chris was an unbelievably excellent, courteous and highly professional technician who even went the extra mile to find me savings on the overall project. The folks at Kingdom Air even referred me to another company in relation to some other projects I need to complete. I hired that company on the spot for my upcoming roofing and deck projects. I have lived in this area (and this house) for 22 years now and I have gone through all sorts of horror stories in simply trying to find reputable, honest and professional contractors and services through the years. I will definitely tell you that there are absolutely no worries at all about those sorts of things happening with Kingdom Air. They are without doubt the very best company I've come across in all of my time here. I would give them higher that 5 Stars on this rating if I could and so you will know that this is a serious review, just ask Kingdom Air to put you in touch with me about your upcoming project and I'll be more than glad to correspond with or talk to you. I'd say that if you want to save yourself some time, effort and possible, "searching headaches," simply go with this company right out of the gate."

"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."

"Terrone responded immediately to our request for service on Saturday. He came to service our air-conditioner which was working minimally. He did fix it and it gave us relief from the heat. However, we knew that our heat pump/air conditioner was in need of replacement. Terrone talked to us about options, gave us some time to do research on the best choice for our home and came back to do the installation. His pricing was reasonable. He and Caleb worked to removed the old system, install the new system, install our new Smart Thermostat ( I-Comfort) and come back to check on the system and us that everything was working correctly. What makes our experience with Mr. Terrone Street so satisfying, both from a professional standpoint of excellent service but also and equally important from a personal standpoint, is that Mr. Street is is a man of integrity, character and dedication. He is honest and attentive, working always to do his very best for his customer as he would want for himself or his family member. He will do his best for you too, with commitment, capability, positivity and honesty."

FAQs for air conditioning projects in Stafford, 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.
