Air Conditioning Service & 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).

Furnace Maintenance Service While it is a term commonly used by contractors and home improvement hobbyist, not everyone knows what HVAC means. HVAC is actually an acronym that stands for "heating, ventilating, and air conditioning." (Yes - it is also an acronym for "high-voltage alternating current" but thats another article.)Sometimes referred to as "climate control," an HVAC system is integral in office buildings and commercial buildings. HVAC systems are extremely common in US homes and that trend is only rising. Depending upon where you live in the US you may "not be able to live without" your AC.So what does an HVAC system do? An HVAC system is designed with the two following major goals: Providing and maintaining "thermal comfort" Maintaining acceptable indoor air quality These goals are often compromised relative to the underlying manufacturer goal of maintaining reasonable installation, operation, and maintenance costs. Many people don't realize that depending where they live either their cooling system or their heating system (both parts of their HVAC) will be the biggest energy guzzler in their homes. To reduce to energy use and thus operational expense of either device energy efficiency is the key. Many recent technological advances have allowed to improve the efficiency of HVAC systems.Energy Efficiency and HeatingThanks to technologies like water heating, geothermal heating and zoned heating - heating systems are in general becoming much more energy efficient. In some cases today's forced air systems can even double for air conditioning systems.Energy Efficiency and CoolingThanks to SEER it's now becoming easier and easier to purchase efficient cooling systems as well. In the USA it's rare to see systems rated below SEER 9 because of the benefits of energy efficiency. Major energy savings can be obtained from more energy efficient systems. Here is an example: Upgrading from SEER 9 to SEER 13, the power consumption is reduced by 30% (equal to 1 - 9/13). It is claimed that this can result in an energy savings valued at up to US $300 per year depending on the usage rate and the cost of electricity. Replacing an existing HVAC system can be a very costly proposition. So many companies are now working on technologies to improve the efficiency of existing HVAC systems.An example of this type of add-on technology is: Cool-N-Save(tm). The Cool-N-Save(tm) is an "Air Conditioner Pre-Cooling System" that works in concert with your existing HVAC system. The Cool-N-Save(tm) system uses purified water vapor to create a "chill zone" surrounding your AC unit. This "chill zone" can reduce the ambient temperature by as much as 30 degrees. By reducing the ambient temperature around your air conditioner, the Cool-N-Save(tm) device reduces the power your AC unit draws. This in turn reduces your monthly electric bill. The Cool-N-Save(tm) gives consumers a simple and cost effective alternative to replacing your entire HVAC or AC system. According to an independent study performed by Tulane University the Cool-N-Save(tm) system can improve the efficiency of your AC by up to 30%.As more and more companies focus on ways to improve efficiency in existing technologies more and more devices like Cool-N-Save(tm) will become available and affordable for the average consumer.
