Oliphant A/C & Heating | Experienced HVAC Services in Richardson, TX

That's a common issue here, especially during our intense summer heat. An overheating compressor can cause exactly those symptoms—loud operation and safety shut-offs. This is often due to restricted airflow, low refrigerant, or a failing component. To prevent further damage, it's best to turn the system off and call us. Our technicians will diagnose the root cause, whether it's a simple cleaning, a refrigerant recharge, or a more involved compressor repair, to get your cooling back safely and efficiently.

You've pinpointed a frequent local problem. When a heat pump blows cold air in heating mode, a faulty reversing valve is a likely culprit. This valve is essential for switching the system between heating and cooling. Over time, it can get stuck or fail. Our experts will test the valve's operation and electrical controls. Sometimes a repair is possible, but if the valve itself has failed, we'll recommend a replacement to restore your heat pump's proper function and keep your home warm.

Two issues top the list: complete A/C failure on the hottest days, often linked to compressor or capacitor problems, and heat pumps stuck in cooling mode during a cold snap, typically due to that reversing valve issue. Both are urgent because they directly impact your home's livability. We prioritize these emergency calls for our neighbors. Our goal is to provide a fast, accurate diagnosis and a clear repair plan to resolve your emergency and prevent it from happening again.
