Quality You Can Trust - Service You Can Depend On
A heat pump blowing cold air during heating mode is one of the most common calls we get. It could be a normal defrost cycle, which temporarily reverses the system to melt ice on the outdoor coil. If the cold air persists, the problem is usually a stuck reversing valve, low refrigerant, or a failed auxiliary heat strip. Our technicians can quickly determine whether it's normal operation or a repair issue and get your heating restored.
Heat pump repair costs depend on the specific problem and parts needed. Simple fixes like a capacitor or contactor replacement are on the lower end, while reversing valve or compressor work is a bigger investment. DVO always provides upfront pricing after a full diagnosis - no surprises. We also offer financing through Wisetack to help manage unexpected repair costs.
If your heat pump is under 10 years old and this is its first major issue, a repair usually makes the most sense. For systems between 10 and 15 years, we weigh the repair cost against the unit's remaining lifespan and efficiency. Once a system is over 15 years old, a new heat pump installation is often the smarter long-term investment. We'll give you an honest assessment - never a hard sell.
Yes, we provide emergency heat pump repair throughout Mesquite, TX and the surrounding DFW communities. Whether your system fails during a summer heat wave or a winter cold snap, our technicians respond quickly with fully stocked trucks so most repairs can be completed in a single visit. Call (214) 460-3239 to get your comfort restored fast.
Light frost on the outdoor coil is normal during heating mode - that's why heat pumps have defrost cycles. However, heavy ice buildup that doesn't clear on its own usually points to a problem like a dirty air filter, low refrigerant, a malfunctioning defrost board, or a faulty sensor. Our technicians address both the ice removal and the underlying cause to prevent it from happening again.
Emergency heat activates your backup heating strips and bypasses the heat pump entirely. Only use it when the heat pump has completely failed, as it costs two to three times more to run. It's designed to keep you comfortable while you wait for a repair - not as a long-term solution. If you find yourself switching to emergency heat often, your system needs professional diagnosis.
During extreme hot or cold weather, it can be normal for a heat pump to run for extended periods. But if it's running nonstop without reaching the set temperature, the issue is usually dirty coils, low refrigerant, a faulty thermostat, or a system that's undersized for your home. Our technicians identify the specific cause and restore efficient operation so your energy bills don't spike.
