Most Common Reasons to Put AC on the Rooftop Unit

People decide to put HVAC systems on the roof due to their large size and noise. If you would like to avoid the noise distraction that comes with an HVAC unit, the best bet would be to put it on the roof.

Also, since rooftop units are typically constructed as all-in-one unit, they are easy to maintain. It saves you the burden of maintaining or repairing several cooling units whose components are typically separated into indoor and outdoor units. This is why commercial air conditioning companies recommend rooftop ACs for commercial buildings; it will save you big time on maintenance fees. 

It is also ideal for people who want to maximize their indoor and outdoor space.

A rooftop unit comes with lots of advantages. For instance, cooling is natural and effortless as cool air directly falls on the system.

Common Rooftop Air Conditioner Problems and How to Repair Them

We list some common issues your rooftop air conditioning unit will likely face.

We also give you tips on how to troubleshoot and try to fix the problem. If the troubleshooting does not work, or if you are having emergency issues, please contact us for Emergency AC repair Santa Clarita services.

The rooftop AC Won’t Turn On

When your rooftop AC doesn’t turn on, the first suspect is power. Check that no breakers are tripped and ensure all fuses are intact.

Also, ensure that the switch powering the rooftop unit is not overloaded. If it is, remove all the other devices and have just the rooftop unit.

If these steps do not fix the issue, immediately call an HVAC expert.

Rooftop Air Conditioner Turns on and Off Repeatedly

If your rooftop unit is short cycling, the first issue to look at is if you have frozen coils.

If you notice you have ice on your coils, turn your system to fan mode. Alternatively, you can switch it off and allow the ice to thaw.

After the ice fully thaws, clean the air filters and the coils.

If, after cleaning the ice still forms, you may be having a bad thermostat or coil issues. Contact your technician to help fix the problem.

Rooftop Air Conditioner is Leaking

When we are talking about your AC leaking, it could be water or refrigerant.

Whatever the kind of leak, you must have a certified HVAC technician onboard. A refrigerant leak is a big blow to your system as the cooling process will not be effective. With low refrigerant levels, your system must overwork to cool your house. This means that the wear and tear will be speedy.

With refrigerant leaks, looking for AC replacement near me is sometimes safe. 

Water leaks from your rooftop system can quickly damage the HVAC machinery. If it leaks down your walls, it can as well be destructive.

If you have a water leak, you need to have a technician look at the sloping of your drain pan and lines.

Rooftop Air Conditioner Not Blowing Cold Air

If your air conditioner is on, but not blowing cold air, then you need to check the indoor coils and the outdoor coils on the rooftop unit.

Are they covered in dust or grime? If yes, then that could be the reason your cooling unit is blowing hot air.

Start by cleaning the AC coils and see if the system starts cooling well.

If not, try straightening the fins using a fin comb. If this does not solve the problem, you are most likely facing a mechanical issue that needs a HVAC contractor on site.
