Important Signs You Need a Furnace Repair Service When it comes to the life span of an average furnace, it usually lasts up to fifteen years, and it is crucial to have regular inspection and maintenance to ensure it is always running smoothly at its maximum functionality until it reaches its life expectancy. 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 your furnace was checked by a professional HVAC technician? If your answer is one year or even longer than that, call a trusted, reliable, and reputable professional furnace technician immediately for the annual maintenance. You filter likely will need to be replaced, and experts actually recommend replacing filters every month. 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 using gadgets or appliances, turning on light switch, and lighting matches or lighters that may start a fire, and contact a local professional furnace or HVAC 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. If your furnace is blowing cold air, then there must also be a problem with your furnace’s pilot light or thermocouple that needs to be checked by your HVAC technician. Improper air circulation, clogged filter, or thermostat complications may cause your furnace to kick on and off repeatedly, an indication that it is over cycling. Obviously, if your HVAC is older than 15 years, you really need a new one than waste your money on repairs and monthly high energy bill.
