"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."

"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!"

"The owner of North Pittsburgh Heating & Cooling came to our house on a Sunday to service our central air conditioning system that was not cooling our house. He said he would not charge us a premium price for a Sunday service call. Upon seeing that our central air conditioner was over 14 years old and used obsolete refrigerant he recommended that we replace and upgrade it with a new system that is compatible with our existing furnace. He gave us a reasonable quote to replace our ac and completed the project the following week. I now have a new working a/c with up to date refrigerant that has a 5 year guarantee on parts and labor and a 10 year guarantee on parts. North Pittsburgh also relocated the condensing unit to the side of our house, corrected the combustion air pipe to our furnace and installed a new outdoor hose faucet."

"I met with 2 or 3 reputable companies in addition to Wade prior to selecting Carrier and Wade for the job. The choice was an easy one. It began with Lonnie, Wade's sales rep. There was no pressure or hype with Lonnie. His communication skills are excellent. Over the course of our discussions, Lonnie prepared several revised proposals at my request as I honed in on what I wanted. Unlike any of the other bidders, Lonnie's proposals were very detailed with costs broken out for various components of the job. I knew exactly what I was buying, both in terms of equipment and services. Lonnie worked with me to reach a fair price. At my request, Lonnie coordinated directly with Air Duct Maintenance so the ducts were cleaned the day prior to the removal of the old furnace and installation of the new. The actual installation was done by Wade installer Ryan, with assistance from Dillon. You will not find a more professional or competent installer than Ryan. During the 2 days that he and Dillon were here, I happened to be working on a project on the same floor as the furnace. In those 2 days, I actually can't recall Ryan ever having a conversation about any topic other than my installation. He was laser focused on my installation. As part of his job, Dillon installed a new pad for the AC compressor. Every aspect of the job was done carefully and neatly. Following the installation, Ryan walked me through use of the new thermostat. He took his time, did not rush me through it and made sure I was satisfied. Finally, every one I have spoken with over the phone at Wade HQ has been friendly, accommodating and followed through when they said they would. If you are replacing your heating and cooling system, I would encourage you to consider Wade H&C. I'm glad I did."

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.
