A couple of months ago, the HVAC unit in my home started malfunctioning. The temperature inside my home soared to over eighty degrees Fahrenheit, even though my air conditioning system ran nonstop. After inspecting my air conditioning unit, my knowledgeable HVAC contractor recommended I purchase a new system. He discussed the pros and cons of installing different sizes of HVAC units with me. After considering my HVAC contractor’s advice, I decided to purchase a three and a half ton HVAC unit. Shortly after my HVAC contractor installed my new air conditioning unit, my house started feeling more comfortable. On this blog, I hope you will discover how an HVAC contractor can help you select the right air conditioning unit for your home. Enjoy!
Sometimes, you can fix air conditioning systems that blow out warm rather than cooled air. For example, this can happen if your thermostat control is on the wrong setting or if your filter is dirty and blocked.
However, this malfunction is sometimes a sign of a deeper problem that needs professional repair. When might you need help to get your system cooling again?
1. Thermostat Failure
If your thermostat is not set to the right temperature, then the air coming out of your system won't be cool. However, sometimes, your control is set at the right level but your air is still warm.
This can be a sign of a thermostat fault. It could have a broken wire or connection. Or, the unit might have broken down, in which case you might need to replace it.
2. Refrigerant Problems
Your air conditioning system uses a refrigerant to cool air. If your system doesn't have enough refrigerant, then it can't cool warm air down enough. Your air will be warmer than it should be.
Your system can lose refrigerant if it has a leak. The larger the leak, the warmer your air will be. You have to find the source of the leak, fix it, and top up refrigerant levels to restore normal cooling.
3. Compressor Malfunctions
The compressor in an air conditioning system circulates air. It moves warm air into the system, cools it, and then moves this air into your home.
As part of this process, this part compresses your system's refrigerant. The refrigerant expands later to take cooling coils down to the right temperature to produce cold air.
If your compressor has a fault, then it might not compress its refrigerant enough for it to expand later to cool its coils. While some compressor faults are fixable, this part often needs replacement when it breaks down.
4. Condenser Breakdowns
An air conditioner's condenser helps manage and remove the hot air your system creates as it works to produce cooled air. This pump contains a series of coils, fans, and fins, all of which remove heat from a refrigerant so that it can create cool air.
If your condenser or any of its parts breaks down, then hot air might get trapped in your outdoor unit. If air isn't released, then it might back up into your system and into your home. Or, your system might only create warm air.
Sometimes, you fix condenser problems by cleaning clogged or dirty parts. Or, you might need to replace some or all of this system.
To fix your warm air problem, contact local air conditioning repair contractors.
