"Highly recommend Kenders HVAC! Both our furnace and air conditioner broke down at the same time, which was a huge stress, but the team at Kenders handled everything flawlessly. They showed up right on time, gave us a very reasonably priced quote, and managed the entire process from beginning to end in less than a week. Their team was professional, efficient, and left everything spotless. If you want honest, high-quality, and fast service, look no further than Kenders!""

"Highly recommend Custom Air Pros! During a heat wave, the AC on my taco truck stopped blowing cold air, and I needed help fast. They were able to come out first thing, found that my refrigerant was low, located and repaired the leak, and added R-410A refrigerant. Before I knew it, my AC was back up and running and blowing ice-cold air again. They were quick, professional, knowledgeable, and really came through when I needed them most. I?ll definitely be using Custom Air Pros again!"

"My parents had used Low Cost Heating and Air Conditioning to have their Central AC replaced last year and when I was ready to replace my 14 year old system that was leaking refrigerant, these guys were my first call. My parents had recommended them to several others who they had done work for and they did not disappoint. Dawn called me back later the day I called apologizing for not calling earlier as they were in a seminar. They set up to come out the next day calling a couple times to let me know they were running late and that they were on their way. Keith pretty much laid out the price and explained everything really well and talked me out of a higher priced system because I didn't need anything fancy and completely trusted him. I made the decision a couple days later to go ahead and they were able to get me in a few days later as they wanted to do it before they started getting really busy with spring maintenance which was fine. The day came and they were a tiny bit late and they called a few minutes before arriving and got right to work. I showed them around and let them get to work. After a few hours, they were all finished up and Keith showed me all that was done and answered a couple of questions. They will charge you 40 dollars for clean and checks and 40 for service calls no matter what time of day and won't charge you anything you don't need. They will be my go to place when it comes to all things heating and air conditioning I had a new 3 Ton Heil 13 SEER Air Conditioning System installed. It included the condensor and coil, they also put in a new disconnect box outside and flushed the existing line set and also put in a new programmable thermostat"

FAQs for air conditioning projects in Canonsburg, PA

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.
