Why there is no cooling in AC?
Unclean Air Filters and Condenser Coils Dirty air filters and condenser coils negatively impact the ability of an AC to cool a room. The dirt and debris that accumulates on the filter and coils trap heat and restrict air flow. This trapped heat causes the unit to overheat and underperform.
What to check if AC is not cooling?
If your air conditioner will turn on, and your thermostat is set properly, but your system is not cooling you may have a dirty or blocked air condenser. Your first step is to check the outside unit and clean around and remove any debris or weeds that are blocking air circulation.

What happens if the thermostat isn't working?
If the thermostat isn't working right, nothing else with the HVAC system will work right. The thermostat is the brain of the entire system. All thermostats need power. Thermostats can be powered by batteries, by a low voltage wire, or by both. If power is compromised, the thermostat will not work.
What to do if your refrigerant is low?
Refrigerant: If you suspect that the refrigerant is low or leaking, call in an HVAC technician. The technician will perform a leak test. If leaks are discovered, they can fix the leak.

How does an HVAC system create a loop?
HVAC systems create a loop by sending air out from the system, through ducts, and out into your house via vents. That same air is sucked back through separate return vent and ducts, back to the unit for re-heating or re-cooling. Any of the vents in this loop might be closed or blocked.
Why is my furnace running constantly?
Possible Causes. The house may be so poorly insulated that the heat pump or furnace is forced to constantly run to keep pace with the demands. Or the outdoor unit might be iced over or have a snowdrift banked against it, blocking the vents. Another cause might be that the return air is so cold, the unit is overtaxed.
What to do if your gas furnace doesn't have a piezoelectric lighter?

What is the A coil on a central air conditioner?
Central home air conditioner service systems consist of two major components: a condensing unit that sits outside your house, and the evaporator coil (often referred to as an A-coil) that sits in the plenum of your furnace or air handler. The refrigerant in the A-coil picks up the heat from your home and moves it to the outdoor condensing unit. The condensing unit fan blows outside air through the condensing coil to remove the heat. The condensing unit houses the three parts replaceable by a DIYer: the AC contactor, the start/run capacitor (s) and the condenser fan motor. The condensing unit also houses the compressor, but only a pro can replace that. The A-coil has no parts that can be serviced by a DIYer.
What to do if compressor doesn't start?
If the compressor starts but the fan doesn't, the fan motor is most likely shot. Shut off the power and remove the screws around the condenser cover. Lift the cover and remove the fan blade and motor. Reinstall the blade and secure the cover. Then repower the unit and see if the fan starts.
What does a blown fuse on a condensing unit mean?
Many disconnect blocks contain two cartridge fuses. Check them before you proceed with repairs. A blown fuse is a sign of a failing part inside the condensing unit. So don't just replace it and think you've solved the problem. Instead, replace the parts, install new fuses, and fire up the unit. If it blows again, call a pro—you've got more serious issues.
How long does it take for an AC unit to reset?
AC units and thermostats have built-in delay features when they're shut down and then repowered. The delay can be as long as 10 minutes. And, if you've subscribed to an energy-saving device from your local power utility, the unit can take even longer to reset. If you've installed the parts shown and reinstalled the disconnect block, repowered the circuit breaker, turned on the switch at the furnace, moved the thermostat to AC mode and lowered the temperature below the indoor temperature, and the unit doesn't fire up after 30 minutes, it's time to call a pro.

Even if your AC contactor is working, it pays to replace it every five years or so. Unscrew the old AC contactor before removing the wires. Then move the wires to the new unit ( Photo 6 ).
Can capacitors degrade over time?
Capacitors can degrade slowly, providing less startup power over time. Or they can fail in an instant. Gradual capacitor failure can go unnoticed for a long time, stressing the compressor and condenser fan motor windings, resulting in their early failure.
Do AC units have capacitors?
All air conditioning service units have at least one capacitor. The capacitor stores electricity and releases it during compressor and condenser fan startup to give both motors an extra jolt of power. And it smooths out voltage fluctuations to protect the compressor and condenser fan motor from damage.
