3 Signs You Should Hire An HVAC Technician

If your furnace or air conditioner won't turn on at all, it's fairly obvious that HVAC repairs are in order. However, there are a few indicators of HVAC problems that are somewhat more obscure. Here are three signs that you should consider hiring an HVAC technician.

Short-Cycling Furnace or Air Conditioner

When your furnace or air conditioner is turning on and off too frequently, it is said to be short cycling. Short cycling can be caused by a number of different problems, the most common of which is a system that is too large for the home that it is installed in. If short cycling is a recent problem, it is likely that your furnace is sized properly and a technical malfunction is causing your system to short cycle.

If your air conditioner is short cycling, the first place you should look is the evaporator coils above your furnace. If the coils are iced over, it is likely that your system is low on refrigerant, which is in turn causing it to short cycle. Furnaces that short cycle may be suffering from fuel or electrical interruptions. A bad thermostat can cause both the furnace and air conditioner to short cycle. Contacting an HVAC technician is the best way to determine the cause of your system short cycling.

Energy Bills Steadily Increasing

If you are gradually paying more on your energy bill each month, but your home energy usage hasn't changed, it is likely that your HVAC system is losing efficiency. While your system will inevitably lose efficiency as it ages, the upward creep in the cost of your bill may be simple to stop if you hire a professional.

A reduction in HVAC efficiency may not directly indicate a problem with your furnace or air conditioner. Instead, a leak in your ductwork could be causing heated and cooled air to go to waste, forcing your system to work harder to heat or cool your home. Other causes of HVAC efficiency loss range from easy fixes, like low refrigerant, a clogged furnace filter, or blocked airflow at the outdoor unit, to more severe problems, such as a malfunctioning compressor.

Your System is Outdated

According to Energy Star, you should consider replacing your air conditioner or heat pump if it is more than 10 years old, as well as your furnace or boiler if it is more than 15 years old. An HVAC technician can inspect your system to determine if replacement is a financially-viable option based on the efficiency improvements you might see.

Knowing when to hire an HVAC professional or heating services is important to avoid sudden system breakdowns and avoid paying extra for an inefficient or outdated system.
