"They cleaned the outside AC unit, checked the charge in the system, and replumed the PVC drain for the AC coil unit attached to the furnace quickly, completely, and for only $140! I already have additional work going their way, just waiting for it to get scheduled. Very satisfied."

"He came out within about 2 hrs of me calling, which was great. He cleaned everything, replace freon, and advised me on how to handle future problems. The best thing was he did not try to sell me a new unit. All of my HVAC equipment in my house is older, and anytime I have had anyone else over for any reason they always try and sell me on new furnace/AC etc. He did not. He was quick and professional and it was appreciated. I will definitely use and recommend him in the future.

"Within minutes of posting on Angi, I received a call from Tiger and had an appointment for an estimate to replace our Air Conditioner scheduled for the next day. Tiger communicated everything excellently, I received text updates with a photo of the tech "Jalen" and the approximate arrival time. Before leaving, Jalen sent the estimate via email and Tiger has sent a couple of follow up texts / emails asking if I have any questions. I chose a different pro based on cost, but was otherwise happy with the professional and quick service I received from Tiger."

Air Conditioning FAQs, answered by experts

No. HVAC, which stands for heating, ventilation, and air conditioning, includes all of the systems that work together to regulate a building’s temperature and humidity levels. In comparison, air conditioners only provide cooling. You can have an air conditioner as part of your HVAC system, but not all HVAC systems include air conditioners.

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.

One of the first signs of mold in an air conditioner is a musty smell. You're likely to notice the smell when the unit runs, from the air coming out of the vents or the unit itself. You may also be able to see mold growing on the unit, such as near the condenser coils or by the fan. In some cases, there may be visible mold by the vents.

Traditional central air conditioning systems require ductwork to circulate air throughout the home. Alternatively, you can add air conditioning with a mini-split ductless air conditioning system, which can be just as energy efficient as a central air conditioner. This type of system consists of two units–an outside unit that holds the compressor and condenser and an indoor unit that holds an air-handler. With multi-zone ductless systems, there are multiple indoor air handlers tied to a single outdoor compressor/condenser, allowing the system to cool multiple rooms.
