Have you noticed that your monthly energy bill has skyrocketed? Do you feel uneven heat at home? Well, it is likely that there is something wrong with your HVAC system and don’t think that DIY repair is a good idea, because your heating and cooling systems have complex components that are beyond your know-how. Call a professional HVAC technician if you experience the following. Increased energy bills An increase in your energy bill is a good indicator that your HVAC is not functioning properly. If you notice fluctuations on your utility bill, it means that you need professional repair or tune-up. Your system uses fuel to keep working at its peak, and if there is a serious problem with the inner components, it will need more energy to compensate for the failure. If these issues are not fixed earlier, they may escalate to more serious problems or even complete failure. Frequent repairs If you are frequently fixing your boiler or heater, it’s time to call a professional for a thorough check-up and repair. When your system is already old and is already beyond repair, your local HVAC contractor will recommended you to invest in a new one. Go over the last two years and find out how many times you needed an HVAC repair. If the repair costs equate to your monthly payment, buying a new heater is a great idea. Age Your heating and cooling systems also have expiration dates. Regardless of how well you take care of it, your unit won’t last forever. Once your system reaches its age limit, you should buy a new one. Buying a new unit can be challenging due to the plethora of HVAC types, makes and models in the market. You can tap a professional HVAC contractor to help you choose the right unit for you. Uneven heat Inspect your home and check if certain parts or areas are warmer than the others are. If there are, it’s a bad sign. One of the functions of your furnace is to distribute heat evenly throughout your space. If some areas are colder, and some are warmer, you can bet that your unit is struggling. Call on a professional to check and repair your unit. Noises and Smells Does your heater produce strange and loud noise? If it produces a grinding, clunking or cranking noise, it is likely that there is something wrong with your unit. Strange noises are a classic sign that your heater is not in good shape. Also, if you smell moldy odor coming from your unit, it can be a sign of poor air quality or water leaks. If there is something that smells like gasoline, it could mean that there’s a more serious issue that needs to be addressed before it’s too late. If you are unsure, whether your unit needs repair or tune-ups, call on a professional technician to have it checked up. A professional HVAC contractor will diagnose any issue and will let you know about necessary repairs, tune-ups, and maintenance.
