When your AC stops cooling your home properly during a summer heat wave in Delta, it can quickly turn a comfortable day indoors into a frustrating experience. Most homeowners expect their system to maintain a steady, cool temperature. But when the air coming out of the vents feels warm, or the system runs longer with no results, something isn’t working the way it should.
There’s no single cause for this type of issue. Several common problems can lead to poor cooling, and spotting the early signs can help prevent bigger problems. Checking a few key areas in your cooling system may give you some quick answers before the situation gets worse.
Dirty or Blocked Air Filters
One of the simplest causes of weak or uneven cooling is a clogged or dirty air filter. Over time, dust, pet hair, and other debris settle into the air filter, making it harder for the system to pull in air. If the system struggles to move air, it can’t push cold air effectively into your home.
When filters are blocked, you might notice:
– Air coming from the vents feels weaker than usual
– Certain rooms are colder than others, despite an even thermostat setting
– A sudden jump in your energy bill without a change in usage
– The AC unit is louder or seems to be straining
It’s a good rule to replace filters every one to three months during summer. Neglecting this task doesn’t just reduce cooling. It also puts extra stress on the AC system, which could overheat parts or cause breakdowns. Some homeowners forget to check the filter after the off-season, especially if the system hasn’t been used for months.
If you’ve replaced the filter and the cooling issue continues, the buildup might have moved into other parts of the system. Our professionals can inspect further and remove blockages that may exist deeper inside the unit.
Refrigerant Leaks That Disrupt Cooling
The refrigerant in an AC system helps absorb and remove heat from the air. Without enough refrigerant, the system cannot cool air efficiently. This usually leads to longer run times or warm air coming out of the vents even when the system is operating.
Signs of a refrigerant problem include:
– Air from the vents feels warm or only slightly cool
– Ice forming on the outdoor unit or refrigerant lines
– Hissing or bubbling sounds coming from the unit
– The system cycles on and off but doesn’t cool the house
Low refrigerant can also damage the compressor, which is an expensive part to replace. Some homeowners assume they can just add more refrigerant, but this does not fix the real issue. Topping it off without sealing the leak only causes the problem to come back.
Finding the leak and repairing it requires special tools and training. Our technicians are equipped to do this safely and restore proper refrigerant levels, which can make a big difference in home comfort during Delta’s warm months.
Thermostat Problems That Throw Off Cooling
One part of the system that often gets overlooked is the thermostat. This device controls when your AC runs, for how long, and at what temperature. If the thermostat malfunctions, it can confuse the system and result in uneven or no cooling.
Common thermostat issues include:
– The AC does not turn on, even when the room is warmer than the set temperature
– Short cycling, where the system starts and stops within a few minutes
– The temperature in the room never matches the number on the display
– A non-responsive screen or incorrect display readings
In some cases, the thermostat itself is working, but its location affects how it reads temperature. If it’s placed near an oven, window, or other heat source, it may misread the indoor temperature and make the system respond incorrectly. For example, one household in Delta noticed their upstairs was always warmer because the thermostat was set up near the kitchen.
Solutions may involve recalibrating the device, repairing internal wiring, or upgrading to a more reliable model. Our technicians can determine if the thermostat is the problem or if the issue lies elsewhere in the system.
Electrical Issues That Disrupt System Function
If the system is unresponsive or shows random failures, the problem could be in the electrical components. Frayed wires, worn-out capacitors, or bad connections can prevent certain parts of the AC from working as they should, even if the unit appears to be powered on.
Examples of electrical faults include:
– Capacitors that no longer hold a charge and stop fan motors or compressors from starting
– Loose wires that cut the signal between the thermostat and the main system
– Relays that fail to switch parts of the system on or off
– Breakers that trip every time the unit attempts to start up
Unlike other AC problems, electrical issues are not always obvious and attempting to fix them without proper knowledge can be dangerous. Our professionals use diagnostic tools to safely identify the exact issue and take care of repairs without causing more damage to the system.
Electrical problems should never be ignored. When left untreated, they can lead to complete system failure, especially during heavy cooling periods common in Delta’s summer.
Improper Installation That Limits Cooling
Even if your AC system is fairly new, poor installation can limit how well it performs. Mistakes during installation may include wrong system size, bad duct connection, or incorrect placement of the outdoor unit. All of these can affect the airflow and how well the system maintains temperature.
Signs of improper installation include:
– Some rooms are too hot even when others feel cool
– The system turns on and off a lot but does not cool consistently
– There is unusual noise when the system starts
– Requiring repairs or servicing too soon after installation
For example, an oversized unit might cool the space quickly, but won’t run long enough to remove humidity. A smaller unit might run constantly but still not cool the space properly, increasing wear and draining energy.
Correcting these problems may require reconfiguring ductwork, adjusting placement, or choosing a better-sized unit. Our technicians are trained to assess current setups and recommend adjustments that achieve better cooling performance and longer system life.
