"The company was paid to diagnose and fix a leak to my roof. They determined that a small patch of roof needed to be replaced. A couple of weeks later the leak continued from the same spot in the ceiling. The tech again came out and claimed it was another leak in a different spot although the leak inside was in the exact same spot. They did not fix the problem the first time and wanted more money for this “new leak.”"

Heating and Air Conditioning questions, answered by experts

If you’re shopping around for a rooftop AC unit, you may hear them referred to as “package units.” That’s because rooftop AC systems are all-in-one heating and cooling units that connect directly to your home’s ductwork. If your AC repair pro references a package unit, they are referring to the system on your roof.

Split systems are the most common type of HVAC system. Split systems have two main units: an indoor one and an outdoor one. These units work together to pull in air, heat or cool it, and distribute it throughout your home. Other popular types of HVAC systems include hybrid systems and packaged heating and air systems.

An AC compressor is one of the most expensive parts to replace on an AC unit if it breaks. You’ll pay up to $2,300 if you need a new one. If your AC is blowing warm air, there doesn’t seem to be a lot of air coming out of the ducts at all, or the unit cycles on and off a lot, you may have a broken compressor. Call a pro to check out your system. 

The right type of HVAC system will depend on several factors, including your climate, budget, preferences, and existing HVAC setup. For example, if you live in an area that experiences extreme weather, then a split system would likely be the best option. Or, if budget is a concern, consider installing a ductless system in just one room.

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.
