"I hired this company to Indy my air conditioner , it was represented by Tom . Hi seemed very nice and intelligent person , so I trusted him . If I only can imagine what they would do to my house I would never let this people close to my house . I am very disappointed and shocked about coming to my home and finding the disturbing mess and unprofessional work done. I have witnessed a few things in the previous days but have not said anything. What I came home to yesterday was disgusting and caused damage to my personal property. Oil was thrown into my shower, dirt all over my rugs in the basement, door broken, my towels beyond filthy with the mess your workers did. Oil dumped all over my shower and me getting dizzy from the smell and almost fainted. I do not need to write anymore as the evidence with pictures explains everything. This is the first time I have experienced such terrible customer service. When I asked them to came and fix a problem which was also don by the company they simply said to me Goodby , we do not care about it à ¢à  à  please didnà ¢à  à  t trust this people you can call me and ask me about the horrible damage they did to my house 203-243-0946 .

Heating and Air Conditioning questions, answered by experts

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.

Ceiling fans can be a great way to cool your home without the expensive utility bill of running an air conditioner. Plus, ceiling fans can sometimes run in both directions, pushing hot air down in winter and pulling cold air up in summer. With that said, air conditioning might be the only thing that helps if you live in a very warm climate.

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.

No, you should not run an air conditioner with a Freon leak. If you think your AC unit is leaking refrigerant, shut it off immediately. When you keep using a leaky air conditioner, it could damage the unit and release more refrigerant. After turning off the AC, have an HVAC pro come take a look at the unit.

You will enjoy greater energy efficiency and save on your annual energy bills, with new, modern HVAC systems using 30% to 50% less energy than older models. Upgrading your HVAC system is also a great way to embrace new technology, such as smart thermostats, lighting, fan speed, and humidity from your phone or tablet.
