Finigan Heating AC - Allison Park's Emergency HVAC Services

Common signs include your AC blowing warm air, ice forming on the refrigerant lines or evaporator coil, a noticeable hissing or bubbling sound from the unit, and a sudden spike in your energy bills. If you notice any of these, it's crucial to call for service quickly. Low refrigerant makes your system work harder, causing further damage and inefficiency, especially during our humid Pittsburgh summers.

In our Allison Park homes, frequent pressure loss in a boiler is often due to a small leak in the system (like from a valve or radiator), a faulty pressure relief valve, or issues with the expansion vessel. While a gradual drop needs prompt attention, a rapid pressure loss or a boiler that won't fire is an emergency. Low pressure can lead to no heat or hot water. We recommend calling us for a diagnosis to prevent a complete breakdown, especially during colder months.

Many refrigerant leaks are repairable without replacing the entire system. Our technicians use electronic leak detectors to precisely locate the leak, often at a joint, schrader valve, or in the coil. We then repair the leak, perform a vacuum test to ensure the system is sealed, and recharge it with the correct amount of refrigerant. We'll always provide an honest assessment—if the repair is not cost-effective or the system is very old, we'll discuss all your options for a replacement that fits your Allison Park home.
