AC Blowing Warm? Tips On What To Do
Is your air conditioner blowing warm air through the vents? There can be a number of causes for this problem. Your best option is to call for help from an experienced heating and air conditioning technician who has the tools and skill to troubleshoot. But there are some things you can do right now.
Our experts at Engineered Comfort Specialist love to help customers learn about their cooling equipment. Call us and we can offer advice as to why your AC is blowing warm and what to do about it.
1. First, turn your AC off and call for help.
Leaving the air conditioning equipment running when hot air is blowing through your vents will cause further mechanical failure if repairs are needed. If you live in the Newnan, GA area, call us at (404) 644-1946 and we’ll help you troubleshoot the cause.
All machines can break down completely if left running in strained condition, so be sure to follow this advice or you’ll wind up replacing the unit early or dealing with more costly air conditioning repairs.
2. Check the outside condenser unit.
Is the fan on top turning? Is there any noise indicating it’s running? Or are there strange sounds coming from it?
If the outdoor part of your air conditioning system isn’t running right, you’ll have warm air blowing through the vents indoors. The condenser outside serves to cool the refrigerant lines that run to the inside air blower. When the refrigerant lines aren’t cooled because the condenser isn’t working properly, the air blown from the indoor unit will be warm. Again, turn off your air conditioner and call a professional to avoid causing more damage.
3. Check the breaker located next to the outdoor condenser unit.
If it’s tripped, there could be a short that needs immediate attention by a licensed HVAC technician. This is another reason you’ll want to be sure to turn the AC off if there is warm air blowing out the vents.
4. Check other vents in the home. Are any producing cool air?
Ductwork is hidden behind the ceiling, so you won’t know if there are air leaks unless they are inspected. Your entire duct system should be well insulated and taped at the joints.
If the joints aren’t properly sealed underneath the insulation or if insulation is missing, vents in certain rooms of the home could be producing warm air or none at all depending on the extent of the problem.
Your experienced and licensed air conditioning tech will be able to spot any problems with ducts. The best technicians have technologically advanced tools to map and pinpoint leaks.
5. Check the AC filter.
We know you’ve heard this time and again, but did you know a clogged air filter can cause the coils to freeze? This means you have no cool air for your home.
Again, turn the AC off and call a technician. Also, take a look at the filter to see if it is clogged with dust and other debris.
Keep the filters changed monthly and don’t purchase the cheapest, as these do little to nothing to keep debris out of your HVAC system. Choose middle of the road filters and you’ll be fine.
