"Joe, from Dryer Vent Wizard was very professional from initial phone call to notifying of arrival time. Several things needed to be handled in my case, venting in the attic, behind the dryer as well as washer hoses. While over all pricey, 8 thought this was fair for the time spent and thoroughness of the work. I purchased my home a couple years ago - and was not completely sure of everything needed (attic)"

"I made an appointment for 3/12/15. They called on 3/9 and said they had an opening for 3/10 between 8am & 12pm, so I took it. The technicians arrived at 8am and explained what they were going to do in detail. Originally I was just getting the air ducts vacuumed but Angel showed me photos of the inside of the ducts and suggested I had them deep cleaned. My house gets very dusty and when I saw my air ducts I understood why. Angel and Piwi worked efficiently, they were polite and professional. They also did an organic santitation of the ducts and a deep cleaning of my clothes dryer. While I was not anticipating spending $800, I understood the need for it to be done, they gave me a discount for being an Angie's List member too. I will make sure I get my ducts done every couple of years and will definitely use National Duct Cleaning Services again.

"The man who came to my house to describe the furnaces and help determine which one I wanted could not have been more wonderful. He was helpful and efficient. We had agreed on a week when the work would be done. The installers called and wanted to come a week earlier. I okayed it, but it wasn't the best day for me. They were nice and efficient. The new furnace appears to be exactly what I wanted. However, the new thermostat control was a different size and shape from the original one and they didn't patch the holes or repaint the edges--not a big deal but when I got a security system a few weeks ago, they did do all that finishing."

"The company sent Joe Wambach out same day as I called for a/c service on a high demand day. Joe arrived on time and was one of the most pleasant HVAC people I've ever worked with, and we've worked with a few in recent years. He went right to work assessing the problems and doing the maintenance work on our equipment. He is a diligent worker, courteous, professional, knowledgeable and trustworthy. He's a great representative for their company and I would hope they appreciate the quality of employee they have in Joe. I did not get other quotes on the a/c unit so I can't comment on price of unit, but it seemed reasonable with everything else that was done. The quote for replacing the air handler coils in attic seemed excessive to me at $2500 but I had no comps; we opted to use original coils."

"We had our upstairs apartment remodeled and needed three fixtures replaced. I purchased the ceiling fan and light fixtures and had Jeff install them. The house is old so the wiring was not in the best condition but Jeff said he had worked on many older homes. He did an excellent job, was very easy to communicate with and was very diligent in his work. After I had the ceiling around the fixtures redone after he installed them the person who re-plastered it could not screw the cap back on so I called Jeff and he came out and fixed it at no extra charge. Another company I called wanted to charge me for an estimate while Jeff gives free estimates, which was a plus. We are very pleased with his work and would highly recommend him!"

"It was okay but nothing special. They did the air duct cleaning by blowing air through and capturing some dust in the basement. They did not appear to remove any of the vent covers and they also offered to "spray" the ducts if we gave them a "tip". After they left I needed to replace my furnace filter as it was full of the dirt and dust from the cleaning. I also had to vacumn out my furnace as they left clumps of dust behind.

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.
