"Would absolutely recommend John Mullen and his company. From the first time I called John he was very responsive and professional. I had called multiple other HVAC companies to install a vent through a brick chimney and were having trouble finding someone who would even come take a look to see if they could tackle the project. John didn't hesitate and came out and talked to us to find the right solution. Once we were ready for the job we were able to schedule him within about two weeks and he called the day of to see if they could come a bit earlier than planned. I truly appreciate the quick and professional communication throughout the whole process. The guys that came with him to do the work were also professional and they got the job done quickly. The price we paid was very reasonable for the length of time they spent and the difficult job of drilling out through brick."

"Twas the eve before Thanksgiving and all through the house all was quiet except for a (mouse) actually it was a circulator pump on the boiler that ran continuously for an hour! Called the number at the shop and by 3 AM John appeared in my driveway in his van with tools in hand and a smile on his face. By 4 AM he was on his way to help other folks, what more can I say! Thanks Air Systems."

"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!""

In the middle of July, when the thermometer is pushing past 100 degrees Fahrenheit, air conditioning isn't a luxury that's nice to have in Pittsburgh—it's an absolute necessity that you don't want to live without. It's obviously a disaster when your air conditioner grinds to a halt on the hottest day of the year. But it's also incredibly frustrating to deal with an AC unit that only "kind of" works and is struggling to get your house down to the temperature on your thermostat or control humidity levels. When you notice those types of annoying issues, it's necessary to get professional Pittsburgh air conditioner repair services before the problem worsens and you're left sweltering in an overheated house.

"Had a great experience with North Pittsburugh Heating. After getting screwed around by our home warranty company for almost 5 weeks (Choice home warranty btw, never use this scam of an agency), I contacted Tim independently to see how quick he could come out and get us a new condenser unit. Tim came out that very day to look at it and got our AC fixed within a week's time at a very good price. The tech's he sent to our house to do the job were also very courteous and helpful, amazing company! A major breath of fresh air after the nightmare we were dealing with previously. We'll definitely be using them in the future for our HVAC needs."

"We were so happy to have Sullivan Super Service (Plumbing, Heating, Cooling) come today to repair our central air conditioning unit and to service our HVAC system. Sullivan's technician, Bob Anderson, was polite, professional and experienced. We greatly appreciated his knowledge and counsel. Our AC has been out for a few days in a current hot spell, and Sullivan was the only company that contacted us. They proved the old saying that in winning, half of the battle is just in showing up and being there. We were not Sullivan customers before, but we are now! Sullivan's service was SUPER!"

"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!"

Customers say: Quick response

"Within 5 minutes told me I needed 2 wires replaced on my AC and it would cost $175. I then asked to see the wires and told him my husband could replace them and I would just pay service charge. He became intense telling me t hat if he had to come back he would have to charge me mileage because he did not realize how far it was and then stated Home Advisor should not of given him the lead because of the distance. My husband replaced the wires and when he did the compressor blew up!!!!!! Bought a new air conditioner from someone not on the Home Advisor list."

FAQs for air conditioning projects in Sewickley, 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.
