"This was my second quote and this company is amazing. Quickly identified the issue, changed the motor, provided a filter and made sure everything was working on one trip within a few hours. The previous company (Air Pros, LLC) said it was unfixable and tried to sell me a new unit over $6k which was a huge scam. Don't go to those guys, work with this family owned honest business. Keep in mind HVAC repairs in many cases are not cheap, I own 3 houses and have paid several hundred or more when an HVAC is old and need repairs."

"Our AC went out in the middle of summer and I called to schedule an appointment and they made it out the same day! They were very professional and completed the necessary maintenance extremely quickly. We had air again by the end of the day. It’s also one of the most affordable places we’ve ever used for our heating and air maintenance and repairs."

"The tenant in my rental property stated she had no cold air blowing. That day I called around for estimates and times to get to it, in busy hot July. I spoke with Moncrief early in the afternoon, and they were able to come out that evening and fix the issue - for a reasonable price, with honesty and integrity. Thanks.

"The technician diagnosed the problem and determined the capacitor was deflected. He replaced the capacitor and explained the purpose of the electrical part. I was extremely impressed with his knowledge of solving my problem. My only concern was that I thought the replacement of the part was exorbitant consisting the online prices of a capacitor for my air conditioning system."

"All Seasons Heating & Air is a friendly, fair, honest, ethical and professional company. I communicated with Brant and was very pleased with his patience to explain things to me and his honesty in not trying to sell me a new unit if I didn't need one. He blew out the pipes of my old unit and now everything has worked perfectly since then. I would highly recommend this company to anyone. They are better than the best!!!"

FAQs for air conditioning projects in Duluth, GA

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.
