Why hire and air conditioner contractors?
Almost all the air conditioner manufacturers require you to get assistance from and air conditioner professional while installing an ac system. If you fail to do so, your warranty may be voided and that would lead to more issues down the line. Moreover, hvac professionals are trained to repair and work with ac systems. If a person who is not trained, tries to repair an air conditioner, he/she may lead to creating more problems or might even injure themselves. Hence it is always recommended to get an air conditioner contractor while working with heating and cooling systems.

How does an air conditioner warranty work?
Every unit comes with a warranty card and toll free tech support number. Warranty card must be filled out by an HVAC installer and mailed as per instructions to the manufacturer’s corporate office in the US.

What are the different types of air conditioners?
There are various different types of air conditioners out there. But few of the most common ac units are:
1. Central Air Conditioning System: This unit is used primarily to cool big buildings, houses, offices, entire hotels, factories, etc. The central air conditioning system is comprised of a huge compressor that has the capacity to produce hundreds of tons of air conditioning. If you have a big area to cool, central air conditioning may be the only way to go.

2. Split Air Conditioner: This unit is comprised of two parts: the outdoor, which houses the compressor, condenser and expansion valve; and the indoor, which is comprised of the evaporator coil and cooling fan. The split air conditioner can be used to cool one or two rooms.

3. Window Air Conditioner: This type of unit is designed to cool a single room. In this air conditioner all the components, namely the compressor, condenser, expansion valve or coil, evaporator and cooling coil are enclosed in a single box. This unit sits in the window. Because of this, it is not the most aesthetically pleasing option available. But if you are looking to cool a single room, it is the most cost-effective option around.

4. Portable Air Conditioner This system is another flavor of the unitary air conditioning system. The portable air conditioner consists of a mobile self contained air conditioning unit that is placed on the floor inside a room and discharges exhaust heat using a hose vent through an exterior wall. Portable air conditioning units are a bit noisier than other types of units and can typically cool rooms under 500 SF. These units are a solution to those stubborn hot rooms that may exist even with central air conditioning. Like the window air conditioner, the portable unitary system has all the refrigeration components on one compact box. It also ejects heat out one end and blow cooled air out the other end.

5. Packaged Air Conditioner: This type of unit is perfect for cooling multiple rooms or a large space in your home or office. There are two possible arrangements with the package unit. In the first one, all the components, namely the compressor, condenser (which can be air cooled or water cooled), expansion valve and evaporator are housed in a single box. The cooled air is thrown by the high capacity blower, and it flows through the ducts laid through various rooms. In the second arrangement, the compressor and condenser are housed in one casing. The compressed gas passes through individual units, comprised of the expansion valve and cooling coil, located in various rooms.

Can you cool multiple rooms with one split air conditioner?
Yes. You can buy multiple air handlers with one condenser. Remember if you just buy one air handler with one condenser that air handler can only blow air in the room its installed. The air from that room cannot easily travel to another rooms with doors and walls around, unless you have a great air circulation setup with fans. Unless it is a open floor plan, normally you need to buy multiple air handlers (indoor units) for multiple rooms. In that case you can connect multiple indoor units to one condenser outside.

For example, when you connect two indoor units to one condenser, they are called Dual Zones. When you connect three indoor units to one condenser, they are called Tri Zones.
When four indoor units are connected to one condenser, they are called Quad Zones. We do have some 5-8 zone systems as well, but they are very rare offered by Mitsubishi, YMGI, Fujitsu and Daikin Brands.

How long does an air conditioner unit last?
With proper maintenance, industry averages suggest that an air conditioner should last 12-15 years (high humidity/salt air applications may be less than that) and a gas furnace should last as long as 20 or 25 years.
