Fast and professional service

Replacing heat pump system in 24 hours is definitely not a small task. But Stan made sure that it was done professionaly. He did not pressure us into buying the most expensive system; he just explained available options and differences between them. Before he left, he patiently went over the system in details and made sure we knew how to use it. I will recommend Stan to any of my friends.

Professional, Competent, Quick & Available on a Holiday!

I found Stan through a Nest thermostat tech support specialist who was looking for a technician to fix my setup so I could have heat again. Stan arrived when he said he would, texting and calling ahead. He seemed very knowledgeable about HVAC systems in general, but specifically knew about smart programmable thermostats like Nest, which is not a skill that all HVAC pros have, not by a long shot. He diagnosed the problem within minutes. He spoke w/Nest agent on the phone to explain things and answer questions, and he filled out a detailed invoice as required by the company for reimbursing costs. Great service.

Stan at Modern Air Solutions is always available and willing to help. His prices are fair and he spends the time to fix the problem right. He takes his time and has a lot of interest in ensuring his customers are satisfied. Modern Air has become my go-to HVAC provider.

Solved the problem

During terrible cold wave noticed that heat was not cycling on at regular intervals. It would heat up the house then go off for up to 10 hours before going back on. I called Modern Air and Stan came out the same day, identified the issue, and fixed it. He is very knowledgeable and good at what he does and will be my HVAC person going forward.

Looking to hire a HVAC company.

Awesome service & workmanship. I was like you looking at reviews to hire someone to replace our heater and AC units but didn't know who to hire. I did my due diligence in researching companies and getting several estimates. Stan showed up on time for the estimate, gave me his thoughts, information and an estimate to make a decisions. We have no regrets on selecting Modern Air Solutions, they showed up on time, did quality work and worked to get our heat working the day before Thanksgiving. I enjoyed working with Stan and Modern Air Solutions, I would highly recommend them.

Courteous and professional

In the height of a heat wave, Modern Air responded quickly to my needs. My air conditioning unit ceased blowing cold air. The modern air team was able to diagnose and correct the issue. Later in the evening I was experiencing a strange behavior with my unit again, Modern Air (Stan) came that evening again to ensure the problem was resolved. Further, he followed up the following day to make sure performance was satisfactory.

Completed a diagnostic scheduling for a club member’s rental property in Philadelphia, PA 19130. The tenant reported that the second-floor heating system was running but not producing any heat, despite multiple attempts to power cycle the unit. The system, located in a bathroom above the bathtub with a large access panel, is difficult to reach and requires a 6-foot ladder for proper inspection. Upon evaluation, our technician identified that the furnace igniter on the second floor is faulty and needs replacement to restore safe and efficient operation. The homeowner approved the repair, and we are coordinating a follow-up visit to replace the igniter, ensuring the rental unit’s heating system provides reliable warmth and comfort for the tenant. This proactive service helps maintain system safety and efficiency in Philadelphia homes during the heating season.

The Ameristar central gas furnace, located in the basement and never previously serviced since 2018, received a comprehensive 21-point inspection and maintenance, including checking the thermostat, heat exchanger, blower motor, safety controls, pilot assembly, condensate lines, and airflow. During the visit, we also investigated the year-long condensation issue at the vents and found no active leaks or malfunctions, ensuring proper airflow and safe operation. The homeowner was pleased with the thorough inspection and restored confidence in the system’s performance for the winter season.

Performed an emergency service visit for a new customer in New Hope, PA 18938 after their Rinnai tankless water heater displayed Code 18 and left the home without hot water. Upon inspection, we found the unit was incorrectly configured for natural gas instead of propane following a prior conversion, which caused repeated shutdowns. We reconfigured the equipment to the correct fuel settings, verified safe operation, and restored reliable hot water just in time for the family’s weekend stay.
