Rated 5.0 out of 5 stars based on 1 customer reviews

Great Service

Because of good BBB and Amazon Home Services ratings for Modern Air Solutions, I contracted with them to install a brand new (first time for my home) air conditioning system. Stan and his worker arrived on time and proceeded to install the indoor coil and the outside unit. Work was performed to my satisfaction, the area was tidied up when they were through and the amount charged was very reasonable. Based on this experience, I would be very willing to utilize Modern Air Solutions again.

Performed an AC service for a cooling performance issue in King of Prussia, PA 19406, where the new customer reported weak airflow and reduced cooling from their 10-year-old AC system. Diagnosed low refrigerant levels and electrical concerns—recharged the R-410A system and restored safe operation.

We performed a critical repair on Sebastian's York AC and air handler system in King of Prussia, PA, addressing issues of freezing and ceiling leaks in the 10-year-old equipment. The technician initially turned off the system to defrost it, later diagnosing it as low on refrigerant. They found no devices to prevent condensation line blockages and a safety concern with the outdoor unit's disconnect box. The technician rewired the disconnect, installed new fuses, recharged the system with R410a freon, added an internal leak sealer, and implemented a cleanable P-trap with a blockage sensor. Our customer was highly satisfied, giving it a 5-star review and signing up for the comfort club for ongoing maintenance. Photos documented the process and improvements. Regular maintenance was emphasized to extend the system's lifespan and efficiency.
