Hot Desert Air Conditioning and Heating | Experienced HVAC Repair in Las Vegas, NV

Signs of duct leaks include uneven cooling, high energy bills, and excessive dust in your home. Our Las Vegas technicians use specialized tools like blower door tests and smoke pencils to pinpoint even small leaks in your attic or crawlspace. We then seal them with professional-grade mastic or metal-backed tape, not basic duct tape, to restore your system's efficiency and lower your cooling costs.

Yes, a stuck reversing valve is a common culprit when a heat pump won't change modes. Our experts will first check for electrical issues and perform a system diagnostic. If the valve is faulty, we can often repair it by cleaning or replacing specific components. If a full replacement is needed, we install a high-quality valve matched to your system, ensuring reliable heating and cooling switching for Las Vegas's variable temperatures.

Prevention starts with regular maintenance. We recommend a bi-annual tune-up—once before summer and once before winter. Our maintenance visit includes checking refrigerant levels, testing the reversing valve operation, inspecting ducts for leaks or damage, and cleaning critical components. This proactive care from Hot Desert Air helps catch small problems before they become major repairs, saving you money and preventing breakdowns during our hottest and coldest days.
