P H T Heating & Cooling - Saint Louis's Experienced HVAC Repair

Common signs include your AC blowing warm air, ice forming on the refrigerant lines or outdoor unit, a noticeable hissing or bubbling noise, and a sudden spike in your energy bills. Since refrigerant is essential for cooling, a leak reduces efficiency and strains the compressor. It's important to address this quickly to prevent further damage.

Leaky ducts force your HVAC system to work much harder, pushing conditioned air into your attic, crawlspace, or walls instead of your living rooms. This leads to uneven temperatures (some rooms too hot/cold), increased dust, and significantly higher heating and cooling costs. Sealing these leaks is one of the most effective ways to improve comfort and efficiency in a St. Louis home.

Absolutely. We are equipped to handle both common St. Louis HVAC issues. For refrigerant leaks, we use electronic detectors to find the source and perform EPA-compliant repairs and recharges. For duct leaks, we perform thorough inspections and use professional-grade sealants or mastic to restore your ductwork's integrity, ensuring all your conditioned air reaches its intended destination.
