"I contacted Petrocelli Services and relayed potential HVAC issues raised by a home inspector on a property my wife and I were purchasing in Austin, TX. I spoke with both Krystal Mitchell and owner Joe Petrocelli. We needed the HVAC inspection performed quickly to stay within a 'purchase option' time period. Petrocelli Services were extremely responsive in scheduling, conducting an inspection and assuring us that the home's HVAC system had no issues to be concerned over. Joe Petrocelli the owner personally talked with me and relayed there was no cause for any concerns, but if anything ever arose in the future to keep them in mind :-)… We certainly will keep Petrocelli Services in mind, and have no reservations in recommending them to anyone requiring HVAC service in the Austin area. They are tremendous!!!"

Heating and Air Conditioning questions, answered by experts

When faced with HVAC issues, it's best to begin by ensuring the thermostat settings are correct for either heating or cooling. If the system isn't responding, check the thermostat for proper function and power supply. It's also important to examine air filters, as clogged ones can decrease performance. Confirm the power supply to the system by checking the circuit breakers and fuses. If these basic steps fail to resolve the issue, contact an HVAC professional for a more detailed diagnosis and repair.

ACs don't run on water. They're not connected to drain pipes or any part of your plumbing system. However, they need refrigerant to run. Refrigerant is a gas or liquid that has a low boiling point and absorbs the heat in your home. ACs need this in order to be functional and cool your home. If you suspect your AC is low on refrigerant, you need to contact a licensed HVAC professional. Refrigerant is a dangerous chemical that requires specialized training and permits to work with. 

If your drain line is clogged, your AC might stop cooling, shut down, or refuse to turn on at all. Otherwise, you might see your AC leaking water, find standing water or water damage near the unit, or notice a musty smell coming out of your air conditioner or vents.

On a summer day, expect your AC to run between 12 and 16 hours. However, this time frame depends on just how hot it is outside and the comfortable temperature you’re hoping to maintain indoors. Assuming the size of your AC is appropriate for the space you’re trying to cool, it shouldn’t be a problem for it to work this many hours.

Yes, you should turn off your AC if it’s leaking. Turning off the system prevents more condensation from leaking and reduces strain on the unit if a damaged internal component or lack of refrigerant is the cause. While this may temporarily stop the leak, water can continue to drip from a thawing coil even after the system is off. As soon as you notice a leak, turn off the unit and investigate the source or call a professional for an inspection.
