"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

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.

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.

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.

Replacing an HVAC system does not always include new ductwork. The decision depends on the condition of your existing ducts. If they are in good shape, correctly sized for the new unit, and meet current standards, they can often be reused. However, if the ducts are damaged, poorly designed, or improperly sized, they will likely need to be replaced or upgraded to ensure the new system operates efficiently. An HVAC contractor will assess your ductwork and recommend the best course of action. Typically, ductwork is purchased separately, and a full replacement will add to the overall project cost.
