"Avery Savage, the Pro sent by Angi was extremely honoest and very proficient. I already knew what was wrong with my HVAC system so I had already purchased a replacement thermostat. I have known other technicians who have tried to get clients to purchase entirely new systems when only a thermostat was needed. Avery was very honest and excellent job access and fixing the problem. I would use this company again and highly recommend Mr. Savage!"

"I had a 20+ year old air conditioning system and didn't want to nurse it through another summer season so I started looking for a replacement during the very polar cold month of February 2019. Of the three bids I received, I was most impressed with Polar Bear Air Conditioning & Heating Inc's responsiveness, professionalism and price. Three days after I signed a contract, Team Polar was at my house at 8:30 am and by 1:00 pm I had a new air conditioning system! The team worked fast, was pleasant, provided updates and handled the one problem encountered, the condenser wouldn't fit through the front door of my old DC townhouse, with grace and humor as they hauled it around the block and in through the back walkway. I'm looking forward to having a cool, reliable and energy efficient system this summer and would definitely recommend Polar Bear Air Conditioning & Heating Inc. to anyone looking for a new system. Thanks again Polar Bear Air Conditioning & Heating Inc!"

"Checked Angie's List and saw a very good review for McCrea Heating and Air Conditioning, plus a special promotional coupon so gave them a try. Service tech (Mike) made a multi-point inspection. He found and corrected some minor issues and added coolant. Fortunately nothing major was required. He was on time and courteous, and readily answered the questions I peppered him with. A very positive experience."

"we had a leak problem and the tech came and looked over our equipment, fixed the problem and left. It cost us nothing and we have had their home heating service contracts for over 20 years. They have NEVER ONCE not shown up or not helped and in the two furnace emergencies we had--they were here with in 1hr.
We are very happy.

"We needed to replace one of our HVAC units and we had a great experience. This is the second unit (we have a two-zone house) that JDL Replaced. Both times we had Carlos lead the work. He was friendly and courteous. He and Rudy did an excellent job with the work, cleaning up, and making sure the system worked properly before leaving. They put down cloth to protect our carpet and are where the unit is. We will continue using JDL Services for ongoing maintenance and other work like this in the house."

"Before I decided to hire Haywood Mechanical, LLC, Mr. Haygood patiently answered all my questions via email concerning his rate to inspect a central air system and what the inspection included. Although I forgot my appointment, Mr. Haygood was very understanding and rescheduled for another day. Mr. Haygood arrived on time, was very pleasant, and took his time testing the central air system, as well as the registers and air vents. His rate was competitive and I will use his services again."
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.
