These are some general HVAC service techniques I’ve picked up over the years, and I’ve written this page hoping these tips will help technicians who are just starting out in our trade. If you’re looking for a more detailed, step by step troubleshooting guide, you might want to take a look at some of the other pages on the site. Start out by getting focused. I think almost everyone would agree that sharp, clear mental focus improves HVAC service and troubleshooting efficiency, and I think that the types of questions you ask yourself while troubleshooting can affect your mental focus. Open ended questions like “Why isn’t this thing running? They’re too general, and allow open-ended and un-focused answers like “Something’s broken. The next two questions to ask yourself on HVAC service and troubleshooting jobs would be: While you’re answering these questions and building these mental pictures of the equipment, you’ll start opening the panels to see what components are inside and start evaluating the condition of those components. While you’re inspecting the components you should start asking yourself even more tightly focused questions like “What is this? The schematics in the equipment, the owners manual, and factory HVAC service manuals will help you identify the components and figure out how they’re supposed to work; and it’s always a good idea to keep a good HVAC book in your service truck for reference.

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.

The Ultimate Guide to HVAC Systems For Rental Properties

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.

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. You need a sump pump that can pump water out as fast as it leaks in, or your basement will flood. With air conditioning, you need one that can pump heat out of your house faster than it leaks in, or your house will still get hot.

The key point is that the air conditioner moves heat.

Modern thermostats with Wi-Fi and backlit display, by contrast, need a steady supply of juice. Technically speaking, power flows from the R red wire, but not continuously not on its own, anyway. To make it continuous requires a common wire to complete the circuit. When the circuit is complete, 24V energy will flow continuously. If your system has a C-wire, it might be in use or just tucked away behind your current thermostat.

Thermostat wire is just a big spool of bundled, color-coded wires. Thermostat wire comes in various weights. Pull back the plastic sheath to reveal the individual wires. It might be stuffed into the wall, which is what some installers do when the C-wire is present but not needed. The ease of doing it this way will vary by furnace and installation.


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.

How to Hook Up a Home Thermostat – If you need to install a new thermostat then you have found the right place to learn. 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.

R — The R terminal is the power for the thermostat. This comes from the transformer usually located in the air handler for split systems but you may find the transformer in the condensing unit. For this reason, it is a good idea to kill the power at the condenser and the air handler before changing or working on the wiring at the thermostat. If you have a package unit then the transformer is in the package unit. Red for the R terminal.

RC — The RC terminal is designated for the power for cooling. Some HVAC systems use two transformers. A transformer for cooling and a transformer for heating. In this case the power from the transformer in the air conditioning system would go to the thermostat terminal. It should be noted that a jumper can be installed between RC and RH for a heating and cooling system equipped with a single transformer. Red for RC terminal. Most installers use the color coding as noted but be aware that some do not use the thermostat color coding.

Verified -Could you explain your situation a little more? With your meter, check that you have 24 volts at the 24 volt side of the transformer. If you verify that you have 24 volts coming out, then hook you 24 volt side to red and common at the furnace control board. So do you think that hooking up the transformer to the blue wires caused the burn out of the previous transformer?

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.
