"These guys are amazing!!!! I hired Old Skool HVAC to come look at my AC system that had failed a few days prior and was not generating any cold air. This is a second home and I was more than 1200 miles away so the visit and inspection had to be done "virtually". Frank came as indicated, after he completed a job in DE later than expected, and YET he still drove to my home late in the afternoon to honor his commitment. I had someone from another company (one that advertises a lot and is a huge company in the Delaware Valley) come out a few days earlier who told me my compressor was shot and would need a $4000 repair, if they could even find the part because the system was old. They also told me that replacing the whole system for $10K+ was the best way to go. That didn't fly with me so I called Old Skool for a second opinion. They diagnosed the problem as a simple fix, one that the other company never even looked for, and now the AC is running perfectly!!!! Frank did this over the phone and was trustworthy, honest, professional, skilled and knowledgeable. I would have him do all of my HVAC work in the future!!!!! I am so grateful to have met him and had this experience!!!!"

"Desmond contacted me immediately and scheduled an appointment. Then they were able to fit me into the schedule a day earlier and called to see if I wanted to move my appointment earlier. Pete came and was prompt, polite and very knowledgeable. He fixed our ac and last night we slept well as our AC finally worked. I highly recommend Desmond."

"Joe and his entire staff are absolutely excellent.  I purposely picked this company based on Joe DiBiase education and experience combined with being a smaller company being more responsive to their customers and that is just what I got for three years now.  Joe also installed a new ductless mini split heat pump in my lower garage for yard tractors and gator.  He also installed new Trane heat pump in basement when I had built out last year.  Both installations were quality jobs at a competitive price.

"There was a snag at the beginning when they realized, after beginning to dig, that the AC unit was on top of the oil tank and they'd have to call someone in to move it before digging could continue. That delayed things a few days, but thereafter they did a good job of digging and were very careful with our trees. They also took care not to ruin the lawn with the machinery. The new tank and heater were quickly put in the basement with no problems."

Air Conditioning questions, answered by experts

Yes, it's normal for air conditioners to leak tiny amounts of water due to condensation. Under normal circumstances, all excess moisture travels to the drain pan to be pumped through your system's drain line. You should call a technician to diagnose the issue if you're noticing frequent leaking or pooling. It's also important to investigate if your homeowners insurance can cover water damage.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

Most HVAC surge protectors last about three to five years, depending on how often your home experiences blackouts or brownouts. If your unit is susceptible to more frequent electrical surges, consider replacing your surge protector every two years. Consult your HVAC professional to determine when and how often to replace your HVAC surge protectors.

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.

Dry mode positively impacts indoor air quality by reducing excess moisture, which stops the growth of mold and mildew. By maintaining optimal humidity levels, dry mode creates a less hospitable environment for allergens and airborne pathogens, improving overall air quality. However, it's essential to ensure proper ventilation to prevent stale air accumulation.
