Important Signs You Need Furnace Repair The average life expectancy of a furnace is about fifteen years, and it is important to have regular maintenance to ensure that it runs to its maximum level. Before your furnace’s lifespan decreases, watch and listen for signs that your heater might need some tuning. The first manifestation that there is a potential problem with your furnace is a neglected or ignored furnace for a year or more. When was the last time you had your furnace checked by a professional HVAC technician? If your answer is a year or even longer, don’t waste too much time and contact as trusted and reliable furnace technician in Philadelphia to perform an annual maintenance. Most HVAC service companies offer monthly services for filter cleaning and replacement, and annual check-ups. A home furnace can either cause gas or water leak, wherein water leak is manifested by water pooling under or around your furnace, which is possibly caused by a clogged condensate line that should be addressed by a professional furnace or HVAC repair technician. If you smell gas, gas leak happens, and you need to shut-off your furnace right away by opening up your furnace, finding the gas supply valve, and turning it off. Avoid turning on a light switch, using gadgets or appliances, and lighting matches or lighters that can ignite a fire, and call a local professional furnace technician as soon as possible. If you are hearing strange sounds at night like scrape, thump, or bang that is a clear red flag needing furnace repair. Air barely comes out from the vents because of issues with the fans, belt or motor, so contact a professional furnace repair technician to rule out the real problem. A definite warning sign that your furnace needs repair is if the thermostat stops working, wherein you need to turn it higher and higher to get the heat you need. Thermostat issues may include loose wiring, blown fuses, or tripped circuit breakers. If your utility bill suddenly increased, it is either caused by a heating issue or AC problem, and an HVAC technician can help in ruling out the problem using his expertise, tools, and equipment. The same is true if your furnace is blowing cold air because it might have issues with pilot light or thermocouple. Thermostat issues, improper air circulation, and clogged filter may cause your furnace to kick on and off repeatedly, a clear indication that your furnace is over cycling. If your HVAC is as old as you and it is more than 15 years, it is high time to have it replaced than waste money on very high utility bills.
