Commercial Heating and Cooling Repair To fix household things that break, you need to know how it works, what can go wrong, how to identify the problem, as well as the steps to fixing it. Here's what you need to know about gas furnace repairs.How Does It Work?Natural or propane gas from an outside source is piped to the furnace where it is burned to produce heat. Usually a fan-driven forced-air distribution system blows the warmed air through ducts that vent into the various rooms of the house. Older gas furnaces use a standing-pilot ignition. Maintenance involves turning off the pilot each spring and relighting it each fall. Newer, more efficient gas furnaces use an electric spark to light the gas as necessary.What Can Go Wrong?Most gas furnaces are quite reliable. What are the symptoms of problems? The furnace may not produce heat or may not produce enough heat. The pilot light may go out repeatedly or refuse to light. The thermocouple may be faulty. The pilot may light but not ignite the burner. The furnace may be noisy. There are some maintenance and a few minor repairs that you can make. However, major service should be left to a trained technician.Fix-It TipTo minimize problems with your gas furnace, take time each month to check the air filter and clean or replace it if necessary. Once a year, clean the blower blades, lubricate the blower motor, and inspect the belt.How Can I Identify the Problem? If there is no heat, check the electrical service panel for a burned fuse or tripped breaker. Relight the pilot light (see below).If there is not enough heat, adjust the burner air shutter (see below); and clean the burner ports (see below).If the pilot light does not light or does not stay lit, clean the pilot orifice carefully with a toothpick, test the thermocouple and replace it if it is faulty (see below).If the flame flickers, adjust the pilot (see below).If there is an exploding sound when the burner ignites, adjust the pilot to a higher setting and clean the pilot orifice and the burner ports.If the burner takes more than a few seconds to ignite, clean the pilot orifice and adjust the pilot light.If the burner flame is uneven, clean the burner ports. If the burner flame is very yellow, clean the burner; open vents in the furnace room to provide more air; adjust the burner air shutter.If the furnace makes a rumbling noise when the burners are off, clean the burner and adjust the burner air shutter.If the air is too dry, wash or replace the evaporator pad if you have a humidifier; test the humidistat; and adjust the water-level float to raise the water level.If some rooms are too cool and others too warm, the distribution system may require balancing. Refer to the Forced-Air Distribution Fix-It Guide at FixItClub.comFix-It TipBe sure your filter is the right size for your furnace.What Parts, Materials, and Tools Do I Need?Some replacement parts for gas furnaces are interchangeable (filters, fasteners) and available at your local hardware store. Others, such as burners and controls, must be purchased from the manufacturer or aftermarket supplier or through a heating equipment supplier listed in your local telephone book.The primary tools you will need for fixing a gas furnace include these:* Screwdrivers* Wrenches* Pliers* Wire brush* MultimeterWhat Are the Steps to Fixing It?To light the pilot on a standing-pilot (always on) ignition system, follow the lighting instructions located near the control. Otherwise, try these steps:Light the pilot:1. Press and hold the pilot control knob to start the pilot. Set the control knob to the pilot position. Hold a long match under the pilot gas port.2. Press the control knob; the pilot should light. Hold the control knob down until the flame is burning brightly (about 30 seconds). Release pressure on the knob, and turn it to the on position.3. If the pilot goes out when you release the control knob, try relighting, holding the control knob down longer. If the pilot again goes out, check the thermocouple (below).Adjust the pilot:1. Remove any cap covering the pilot adjusting screw on a combination control. 2. Turn the adjusting screw counterclockwise to increase the flame or clockwise to decrease it. It is correctly adjusted when the flame envelops the thermocouple bulb by 1/2 inch and appears dark blue with a small yellow tip.Test and replace a thermocouple:1. Hold the control knob to pilot and light the pilot as above.2. Unscrew the thermocouple fitting with an open-ended wrench.3. Set a multimeter to the DVC (lowest voltage) scale.4. Clip one multimeter lead to the end of the thermocouple tube nearest the pilot and the other lead to the fitting on the other end of the tube.5. If the multimeter shows a reading besides zero, the thermocouple is functioning. Replace the thermocouple tube.6. If there is no reading, you will need to clean or replace the thermocouple following steps 7 through 11.7. Release the control knob and shut off the main gas valve on the gas-supply pipe that leads into the burner. Shut off power to the burner at the electrical service panel .8. Remove the thermocouple from its mounting bracket.9. Wipe the combination control clean and install a new thermocouple, tightening it by hand, then give it a one-quarter turn with a wrench.10. Insert the thermocouple into the pilot bracket, being careful to not crimp the tubing.11. Turn on power to the furnace and relight the pilot (above).

Home HVAC Maintenance An HVAC system is a large investment on your part. We're not just speaking in reference to the initial costs of purchasing and installing the equipment, but we're also referencing the amount of money you will spend on energy bills over the years. Statistics say that you will spend well over $2,000 this year on energy bills alone. Your HVAC system accounts for almost half of the energy your home consumes within that time period. Your home, no matter how old or new, is an energy hog. Whether you're choosing to upgrade your existing HVAC system or installing a new one in your new home, here are some tips you should adhere to in order to choose the proper-sized system that will ensure energy-efficiency.So what does one do to prevent your home from sucking up so much energy? First, understand that if your equipment is old, it's time to replace it. Equipment that is 10 years or older is extremely inefficient and should be replaced, preferably with an energy-efficient model (i.e. Energy Star qualified). When purchasing any type of HVAC equipment, it's smart to go with an energy-efficient model. It will save you a ton of money over the years. You're probably wondering, "So if I choose energy-efficient equipment, why does sizing matter?" It matters! Choosing the proper-sized equipment (i.e. proper heating/cooling output) directly affects your comfort, your HVAC system's efficiency and its maintenance and operating costs. You can see how important and underestimated this topic is. In fact, it has been estimated that over half of the HVAC industry does not size your HVAC systems properly."Oversizing" tends to be the biggest mistake that is made. When you oversize an HVAC system, it can affect a number of areas within the process. For example, the installation will be more expensive. Typically oversized systems tend to cost more to operate, break down often, run inefficiently and require more maintenance. Oversized air conditioners tend to shut off before they've had a chance to dehumidify the air properly. This results in a clammy environment that may be prone to mold. Oversized furnaces create uncomfortable temperature swings.When your HVAC technician attempts to size your system, they should not be reading a label or simple by-the-book standards. Instead, the calculation should be multi-variable and include factors that are unique to your situation. For example, what is the climate like in your area? How many windows do you have and what size are they? How much insulation is there and what type of insulation is it? How big is the house? Is the house two-story or one-story? How much outside are is sneaking in? How many occupants are there? There are two industry standards that should be used to help determine the proper size for your system. These are "Manual J" and "Manual D", created by the Air Conditioning Contractors of America. Manual J, also called "Residential Load Calculation", is primarily used to determine HVAC size calculations. A reputable HVAC company will tell you that they use Manual J to determine sizing. Manual D, also called "Residential Duct Design", is used to determine duct sizing. When looking for a company to help install your new HVAC system, always be sure to inquire whether or not they use Manual J and D in their sizing and installation process. Replacing A Gas Furnace
