Willco handles a wide range of residential AC repair issues in Sussex County, including air conditioners that blow hot air, won’t turn on, and have weak or uneven cooling. So, if your air conditioning is acting up and you’re not sure why, that’s okay. You don’t need to pinpoint the issue—that’s our job.
Our HVAC technicians have seen and solved it all. We handle refrigerant leaks, sensor problems, dirty filters, electrical issues, and more. Each repair is carefully assessed and executed so that you don’t face the same problem twice.
Common types of cooling problems include:
If your cooling issues are paired with musty smells or allergy flare-ups, the problem may extend beyond your AC. We also offer indoor air quality solutions to help you upgrade your system while addressing repair needs.
Your home comfort matters. That’s why we offer prompt, same-day service when possible. If your cooling system breaks down suddenly, we’ll do everything we can to get you back up and running quickly.
Emergency service often makes sense when:
Not every repair requires an overnight call. If the system is still running, the cooling issue is mild, and there are no safety concerns, it may be able to wait until regular hours.
An AC that will not turn on can have several causes. Sometimes the issue is a tripped breaker, a thermostat problem, or a disconnect that needs attention. Other times, it points to an electrical or control issue inside the system.
Your air conditioner won’t start if a breaker is tripped. To determine if one has been overloaded, find your home’s main electrical panel.
If your thermostat isn’t signaling your system to start, it won’t switch on. The most important first step is to make sure it’s set to “cool” and not accidentally to “heat.”
If you’re using a traditional thermostat:
Your AC probably has a shut-down device around its condenser. This device is commonly in a metal box attached to your home. If your equipment was recently repaired, the switch may have been accidentally left in the “off” position.
Condensate drain pans collect the extra water your cooling system removes from the air. This pan can be found either beneath or within your furnace or air handler. When there’s an obstruction or blocked drain, water can build up and trigger a safety control to switch off your system.
If your pan has a PVC pipe or drain, you can remove excess condensation with a custom pan-cleaning capsule. You can purchase these capsules at a home improvement or hardware shop.
If your pan has a pump, locate the float switch. If the lever is “up” and there’s water in the pan, you may need to replace the pump. Call us at 973-270-9244 for help.
Warm air does not automatically mean you need a whole new air conditioner, but your system does need attention. If your system is on but not blowing cold air, it may be due to restricted airflow, low refrigerant, or a problem with the indoor coil or outdoor unit.
A clogged air filter can cause a lot of problems, like:
We suggest changing flat filters once a month and accordion filters every three months. You can locate the filter in your furnace or air pump’s blower compartment, or it could be in an adjoining filter holder or wall-mounted return air grille.
If you can’t recall when you last changed your air filter, now is a good time to shut off your AC and pull out the filter. If you see a lot of dust, it needs to be replaced.
Weeds, grass, and leaves can obstruct your condensing unit and reduce airflow, making it less energy-efficient and effective. Here’s a way to get your system running better.
When cooling equipment doesn’t have enough refrigerant, it has to work much harder to remove heat and humidity from your house.
Here are a few signs that your equipment is leaking refrigerant:
If you think your system is leaking refrigerant, you’ll need a licensed HVAC technician to repair the leak and restore the proper refrigerant level in your equipment. Get in touch with us at 973-270-9244 for support.
When it seems like you’re not getting enough airflow, there’s likely a blockage or detachment somewhere in your air conditioning system.
Weak airflow puts additional strain on your system. The sooner it is checked, the better.
