Turn off the gas supply valve, typically located by your gas meter on the gas inlet pipe. Turn off the gas by rotating the valve one quarter turn with an adjustable wrench. When the gas is off,  the valve’s oblong stem points perpendicular to the inlet pipe. Then call your gas utility or the fire department from a remote location. Do not return to your home until you know it is safe.
For starters, once a year, vacuum out the area around the furnace’s blower. If possible, also slide out the fan unit, clean each fan blade with a toothbrush, and then vacuum with a brush attachment on a vacuum cleaner. While you’re at it, look for oil ports on the motor, normally located near the motor shaft. If the motor has these, apply two to three drops of non-detergent motor oil into each port (you may have to remove a cover plate to do this). Though most contemporary motors don’t require lubrication, do lubricate motors with oil ports once a year. For more about maintenance, see Maintenance Checklist for Central Heating Systems.
Regarding your post, Every technician performs a maintenance differently. Today's modern furnaces really don't require as much maintenance as older style systems did. For instance: Older furnaces had drive belts, pulleys and motors with oil ports.Today's blowers are direct drive no belts, no pulleys, sealed bearing motors no oiling required. All of the new modern technology cuts the maintenance time in half if not more. Today's equipment has multiple safety's in place so that in case of a failure the system will shut down. non serviceable control boards or (Brains) monitor system functions. Unlike oil systems, the maintenance on a gas system can possibly be completed in less than half the time. I'd say 20 to 30 minutes is about right unless a service issue arises. In the 30 minute time span, the doors can be removed, system components can be visually inspected, the flame can be inspected and co test can be performed for spillage and vacuum of the combustion area can be performed if needed. The air filter should be checked and the humidifier can be activated. Remember that probing into a perfectly functioning system can be detrimental to its lifespan. My advice is change you air filter, keep the area around the equipment free of dust and try not to store in close proximity to the heating plant. Be sure you have an updated quality carbon monoxide detector in your home. Regarding the crack in your heat ex-changer, If the heat ex-changer had a crack in it, the system it should have been shut down right then and there. Be aware that Carbon monoxide may be entering your living space due to that crack. Have a knowledgeable company come back and do a CO test in your home at the supply vents and use a scope to check your heat ex-changer for cracks. I hope this helps you. Bottom line, you have to trust the company that you are using. If you feel uncertain about their capabilities, then more than likely, you instinct is correct. Good Luck to you.. Happy Holidays
Sometimes a heating and air conditioning system just needs to be repaired rather than completely replaced. You may need air conditioning repair services if there is leaking around the outside unit, the air coming into the house isn't hot or cool enough, the unit is short-cycling or constantly turning on and off, using the system is consistently resulting in higher-than-normal energy bills, or if there is excessive noise during startup and operation.

Customer stated their blower fan is consistently running. She has had the furnace off all summer and just fired it up and it will just blow consistently. Upon investigation, the technician found that the damper control was sending 24V to G terminal while switched off. This indicates a stuck closed relay. I disconnected it and tested the unit. Due to age of unit, I would recommend upgrading to a more efficient model.
Your HVAC system is an important appliance with a limited lifetime. Depending on use, with regular maintenance you can expect your furnace and air conditioner to last between 8-18 years before you will need to replace the old one. However, poor maintenance is one of the primary reasons for early replacement HVAC systems ahead of end of average life expectancy.
The cost to replace your gas furnace will vary based on the type and size of furnace you select, labor and installation costs, and any repairs your HVAC system may need. Nationally, average HVAC prices for a heating specialist range between $1,800 and $2,500. It’s important to select the right size gas furnace for your heating needs. A furnace that’s too small won’t heat your house properly, while a furnace that’s too large will run inefficiently, cycling on and off and likely breaking down sooner. HVAC specialists calculate your exact heat needs by measuring your home and incorporating variables such as the regional climate and your home’s level of insulation. Retail pricing for gas furnaces can range from $650 up to $3,000 and more. The higher the AFUE (annual fuel utilization efficiency) rating of the furnace, the more efficient it is at turning fuel into heat and the lower your carbon footprint and utility bill will be. HVAC installation costs are often based on an hourly rate and can range from under $50 to over $100 per hour, depending on the company and the furnace being installed. Higher-end furnaces cost more to install because they require added labor and expertise. For a typical installation, it might take two HVAC installation pros one day or less to remove your old furnace and replace it with a new one.
Finally, don't underestimate the thermostat as a potential reason why your furnace is not working. Everything on the heating unit itself may function perfectly, but your home still will not heat right if the console you use to set the temperature doesn't communicate your input. A faulty thermostat can either be due to the wall unit itself, or the wiring that connects it to your furnace. Average thermostat repair costs are between $108 and $282, including labor. Replacement costs, of course, depend on the thermostat you choose. Visit our thermostat repair cost guide to learn more about this type of issue.

Great article! I am having trouble identifying what to use for the aluminum or zinc strips to prevent organic growth and staining. How wide are the strips? Are they predrilled? I am starting to see black stains on the north facing asphalt shingles. Do you recommend treating that befor adding the metal strips? If so, 50/50 bleach and water or a commercial product?

Richard sets up a combustion analyzer, which calculates furnace efficiency by measuring gasses in the exhaust flue. He makes sure that the burner's air gates are adjusted for the proper ration of fuel to air. "You want the fuel that you've brought to the be burned before it goes up the chimney," Richard says. He also replaces the oil nozzle, which atomizes the fuel just before it ignites, and checks the flame color and shape at the igniter. For either oil or gas, this is a key indicator of stable and complete combustion. In a gas system, this is the time when the burner tubes should be vacuumed clean.
Your heating and air conditioning system naturally loses energy efficiency over time. This loss of efficiency is due to many factors, including dust and dirt, natural wear and tear, and buildup in drains or on burners. Keeping your heating system maintained with regular professional tune-ups can help to reduce these factors. During your tune-up, your maintenance technician will clean and check over your heating equipment, identifying areas of wear and tear. They can identify failing parts in need of replacement before they become a serious problem. A tune-up alone may instantly improve energy efficiency by up to 30%. You’ll also enjoy cleaner air and a cleaner residence because your HVAC system will be distributing clean air through a clean air filter. Perhaps one of the greatest benefits you’ll enjoy following a fall furnace or AC tune-up is decreased utility bills. A neglected HVAC system must work much harder to heat and cool your home, while a furnace or air conditioner that has been finely tuned can take less energy to maintain indoor comfort. Because your heating system will function more efficiently, it will deliver superior heating at lower cost than you otherwise may have had through the winter season.

When it comes to heater repair in Denver, a properly serviced system means significant savings for the homeowner. When a Denver heating technician inspects your system before the winter sets in, the first thing they will check is the condition of the air filters. These filters are important, because they are responsible for removing contaminants, allergens, and dust particles from the air every time the system is turned on. When the filters are clogged, expect more particles to easily pass through right into the air you breathe inside the home. The Denver heating experts will inspect and replace any filters that are no longer effective.
