"Received prompt call after setup on Angi. Wagner HVAC did service call on AC unit had issue with fan motor not turning on. TEMP WAS 90 degrees plus in house. Diagnosed that fan motor ok. Found issue with new thermostat that was not wired correctly. Checked compressor for faults. Other providers actually quoted replacement. The price for the service call saved me thousands. I would highly recommend WAGNER HVAC AND REFRIGERATION LLC to everyone. I intend to purchase maintenance plan with them also."

Heating and Air Conditioning questions, answered by experts

Capacitors are the most frequent part of an HVAC system to experience failure. These components are crucial for starting the motors that power the fans and compressor, but over time, they may become worn or fail due to electrical surges or regular wear and tear. When capacitors malfunction, HVAC systems may experience decreased heating or cooling efficiency, or even total system failure. Replacement or maintenance of capacitors is a common requirement for the optimal functioning of HVAC systems.

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.

High humidity is one of the most common reasons for air vents to sweat or produce condensation. When the cool, dry air from your HVAC unit meets warm and moist air in your home, it will cause condensation. Insulating your ductwork can help prevent this. If you live in a very humid region, a dehumidifier can also help.

Here’s the cost formula to find out how much it’ll cost you to run a window air conditioner in your home:  Watts * (hours used) / 1,000 * (Local kWh) = daily cost of running a window unit. If you need help calculating the cost of running your window AC unit, consult an AC repair or installation pro for an accurate estimate.

When a compressor gets overheated in central air systems or heat pumps, it can still cool your home for a while until it eventually gives out. If the compressor is chronically overheated and no one addresses the root cause, it will create an incredibly expensive problem when your entire HVAC system breaks down and stops working altogether.
