"Our central air unit died during the hottest days of the year so far. It is a new unit . We called a few places desperate for service and were told it would be a few weeks for most companies to make it out. Called Landrys after finding them on google. A woman called me back less than 20 minutes after first phone call and said they would be out today. Tyler came and was great. Fixed our unit and saved our life! We will be using them in the future for sure. 5 stars for service and their customer service is without a doubt 5 stars as well."

"I had an excellent experience with Stephanie, Tim, and Spencer during the installation of my mini split system. From the very beginning, they were professional, friendly and communicative. They took the time to explain how the installation process would work and made sure I understood all the benefits of swtiching to the system. I felt well informed and supported. Since the installation, the system has made a huge difference in my hosuehold. The units are quiet, efficient, and give me the ability to control the temperature in all rooms in my household. Not only does it keep the space comftorable by replacing AC's but I've noticed the air quality and drop in my electricity bills are better. I"m grateful for the work this team did and would recommend them toothers. I trust them completely and wouldn't hesitate to use them in the future again. Thank you!"

"Could not be happier with the install of our new propane system. They were very easy to work with Quinn answered all my questions Doug and Bernie and I forget the other guys name were a pleasure to have in my house. They did the work and the Quoted amount of time. They handled all the inspections and permits with the town. Extremely happy with the level of service and would recommend to anybody looking for heating needs. Edit from 2 years ago?. The company still has not picked up old water heater and boiler. Have called a number of times to get this done. Vicki is extremely unpleasant to deal with. Rude. Has zero phone skills. Should really look into finding a new person to answer the phones. She was basically yelling at me for asking, follow up questions. And when I I said, why are you yelling? She said so you would know if I was yelling at you. But she definitely was yelling. I really hope those phone calls are recorded. They?ve got their money. So obviously the customer service ha"

"Excellent! Joe and his staff were friendly, helpful and timely. They maintained COVID protocols for me/my family’s safety and went above and beyond to repair some unexpected issues. I also found cost to be very reasonable. 10/10...Plan to use them in the summer for my HVAC duct cleaning!"
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.
