The installation of a new central air conditioning system should always be performed by a licensed professional HVAC installer. Attempting to install a new cooling unit without the proper training and knowledge can be dangerous. Improper installation can cause damage to the cooling system, as well.

How to Support a Window Air Conditioner Heating, ventilation and air conditioning, known as HVAC, systems can be complex in large or multistory homes; but in manufactured homes, they are one story, straight-line systems. Manufactured homes seldom come with air conditioning, especially in areas with cold winters. Adding air conditioning to an HVAC system in a newer manufactured home is a matter of adding an evaporator coil and drip pan to the existing air handler and a condenser unit alongside the building near the utility closet.

Older manufactured homes may not have air handlers and require both air handler and upgraded furnace. Turn off the gas at the meter if the furnace burns natural gas. Models may have different fittings and assembly requirements; read the complete directions. In manufactured homes, the plenum is under the furnace, since ductwork is typically installed under the floor.

Slide the evaporator coil onto its rails in the cabinet. It sits underneath the blower and above the exit to the plenum on a downflow mobile home system. Seal the ducts with mastic and fiberglass tape or butyl tape, as directed in the air-handler instructions. Tighten the bolts until they are firm; loose bolts can rattle loose. Manufacturers recommend that you match their furnaces and air handlers because they are made to fit together.

Look for a spot that is strong enough to support the unit and allows the unit to be serviced easily. Level the unit and place on treated lumber or steel framing. Anchor the unit down to prevent the unit from shifting during operation. Inspect the unit and ensure no components have come loose during shipment. Check all bolts, electrical connections, etc. Properly size all copper tubing using a line chart. Install and braze the copper tubing for the liquid and suction lines.

When brazing, flow an inert gas like nitrogen through the lines to prevent scale and oxidation in the lines. The copper tubing will hook up from the condensing unit outside to the evaporator coil on the indoor unit. Secure and support all lines with copper pipe straps. The smaller the pipe, the more straps you will need. Leak-check the unit by opening all service valves and pressuring the unit to PSI with dry nitrogen.

How to Install a New HVAC Condenser Unit

I get this question a lot and I also see this question used in my stats on how people find the site but I do not believe I have directly addressed or dedicated an article to this subject yet but there are residential HVAC systems out there that use 2 transformers and it befuddles some people. In commercial systems, you can have several step-down transformers in a single unit that will break down the voltage from volts all the way down to 24 volts and everything in between but in residential systems, there is usually only a need for one step down transformer to provide a control voltage for the entire system.

Read on for more explanations. The only requirement which I am aware of that would be applicable to the NEC would be running the wire in a plenum if the wiring is not plenum rated wire no matter the voltage. How Can I Tell 1 or 2 Transformers for Heating Cooling System – VA Rating One other additional note about using a single transformer in residential versus sometimes using multiple transformers in commercial units: Every transformer has a VA rating on it.

Hook Up kits or the FCU Links as it is called are Terminal valve assemblies has been designed to include all of the valves and and connections for controlling and maintaining terminal units.

Gauges are used to read the pressure of various liquids and gases in a cooling system, as well as vacuum pressure when you are pressure testing or charging the device. There are a number of different ports on the HVAC gauge set, also known as a manifold, and the main difference in the types of manifolds is the number of ports that you have available to attach accessories to, as well as the pressure that the gauge set can withstand, which is important when working with different refrigerants.

Step 1 Connect the high pressure side of the cooling line to the red port on the gauge. The red port and red gauge are always the high pressure gauges. You will want to attach a code-approved red hose, which is made to withstand high pressure, using the flare fittings that are included with it, to the high pressure port on the cooling unit. The high pressure port is typically of a different size and thread pitch than the low pressure side in order to avoid the potential for accidental incorrect hookups.

Step 2 Connect the low pressure side to the blue port on the gauge. The low pressure side will be connected with a blue low pressure hose to the blue pressure gauge and the low pressure side of the cooling unit. This will allow for the proper flow of vacuum pressure or a micron meter in order to determine the vacuum pressure in the system already.

Thermostat C Wire: Everything you need to know about the “common” wire

Below we will describe to you how to hook up a digital thermostat, hook up a programmable thermostat, or hook up any type for that matter. Whether the old thermostat is bad or not if you simply want to replace your old one and hook up a new one the first thing you need to take into consideration is to select the right replacement thermostat. To select the correct replacement you need to know what kind of HVAC equipment you have in your home or where you want to hook up the new thermostat.

There are numerous types of air conditioner and heating combinations so in this article we will cover a basic gas furnace and air conditioner split system HVAC system. Thermostat Wiring Colors Code – Learn More about the Thermostat Installation opens in a new window How to Hook Up a Home Thermostat If you do not know what kind of unit you have take a look at the paperwork from the last time the unit was serviced.

Perhaps it will show the type of equipment on the service ticket where the unit had maintenance.

The HVAC gauges and AC hoses are color coded. The manufacturers color coded the exteriors of the HVAC gauge (compound gauge and high pressure gauge) to distinguish between high pressure and low pressure gauges.

An air conditioner and furnace is a popular matched system in the Northeast, the Midwest and some places in the South. What does an air conditioner do? Connected to the inside cooling coil, the compressor pumps refrigerant back and forth, extracting heat and moisture from the indoors. It transfers the heat to the outdoors. Warm indoor air is blown over the indoor cooling coil, where it is cooled and then distributed throughout your home.

To deliver the highest system efficiency, performance and climate control, an indoor cooling coil must be matched in size and rated with your air conditioner.

HVAC: Install an Air-Supply Line and a Cold Air Return

The systems set up to allow objective comparison of air conditioners are hindering that very goal because of the many different measurement systems and terminology. Before discussing the different terms I would like to quickly explain what an air conditioner does: Much like a sump pump pumps out water from a basement or crawl pace, an air conditioner pumps heat out of your house.

How It Works Given all the attention being paid to solar power these days, you might be surprised to learn that one of the most promising solutions to high energy costs isn’t up in the sky but buried deep under your lawn. Superefficient geothermal heat pumps provide clean, quiet heating and cooling while cutting utility bills by up to 70 percent. In principle, a geothermal heat pump functions like a conventional heat pump, by using high-pressure refrigerant to capture and move heat between indoors and out.

The difference is that conventional systems gather their heat—and get rid of it—through the outside air. Geothermal systems, in contrast, transfer heat through long loops of liquid-filled pipe buried in the ground. As our cave-dwelling ancestors discovered long ago, if you go far enough underground, the earth’s temperature stays at a constant 50 degrees or so, no matter how hot or cold it gets outside.

So while a conventional “air-source” heat pump struggles to scavenge heat from freezing winter air or to dump it into the summer swelter, its “ground-source” counterpart has the comparatively easy job of extracting and disbursing heat through the degree liquid circulating in its ground loop. That’s why it takes only one kilowatt-hour of electricity for a geothermal heat pump to produce nearly 12, Btu of cooling or heating.

To produce the same number of Btus, a standard heat pump on a degree day consumes 2. Geothermal systems are twice as efficient as the top-rated air conditioners and almost 50 percent more efficient than the best gas furnaces, all year round. Another advantage is that there’s no need for a noisy outdoor fan to move air through the compressor coils. Geothermal units simply pump liquid, so they can be parked indoors, safe from the elements.
