"I'm so annoyed that every time I cooked in the kitchen on the main floor the cooking smell go straight to the basement and my roommate is constantly complaining and he brought in a guy claiming that this guy can fix the problem. The was never fixed and cost me a good amount of money which made me mad. I looked up the comments online and find out how great people talked about Matthew. Through his trained eyes , he educated me how the HVAC system works and what's the problem and what steps should I take to solve the problem. Matthew pointed out to me that when I cook, I have to have the intake air (which I don't) in order to replace the exhausted air. The problem is my kitchen duct vent that takes the exhaust air to the outside is pointed downward right above my kitchen windows and one of them has the exhaust fan; so the smell comes out through the exterior duct vent and goes back into the house through the portable window exhausted fan. The solution is to open one window and turn off the thermostat during cooking. The best solution is to call Bray & Scarff to fix the duct vent. Matthew impressed me with his knowledge and professionalism. Thanks Matthew."

"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."

"The quality of the work was great, it is the product I am not sure about. Just had the system put in last year and the mother board needed to be replaced. While it took longer than expected to receive the part, once received, it was replaced the next business day. The technicians were knowledgeable and efficient. They replaced the part and performed the inspection; and explained it all so I could understand what they did (they even replaced the air filter without my asking). I have used this company for over ten years and find their employees willing to help me keep my system running smoothly and efficiently. I highly recommend McCrea of VA for your HVAC needs."

"We had them Replaced furnace and air conditioning unit. It was installed about a year ago but they came out for a regular service about a month ago. the service was free, part of the contract. I have no complaints, it was all good. They were responsive. they were punctual. I have no problems, it was a good deal when I bought it, it's a good deal now. I don't have any issues with how the service went. i bought it through them and I have no regrets and everything was the same as I felt when I bought it. It was a good deal, I made the right choice. Anytime you buy a major system and it doesn't go right you have a problem. I'm a happy camper.1 worker took less than an hour to complete."

"The team was very helpful with identifying the issue with our heating system and providing guidance on how to proceed. We replaced the entire system (which was 10 years old). Very happy with the end result. The air is so much cleaner and my son's allergies have significantly reduced."

FAQs for air conditioning projects in Gainesville, 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.
