Tips for Identifying HVAC Maintenance Problems

Some HVAC problems require cleaning of coils and filters only. This is something you can easily do yourself. On the other hand, many of the ten most common problems with the heating and cooling system become much greater concerns when not serviced in time. You can ignore most of them by regular precautionary calls for maintenance. It is advisable to check your system annually for extreme weather conditions to avoid outages. You can contact professional HVAC contractors to find detailed information about the HVAC problems and to get a discount on all repairs or plumbing.

Common HVAC Maintenance Problems

1. Call Certified Technicians to Inspect Your System

You must contact a service contractor that has a license. They will keep your system in order with regularly scheduled maintenance. For more information about maintenance programs, click here. With proper maintenance, a certified service contractor can avoid many problems that are related to the furnace. Your system of home heating probably must have cost thousands of dollars. Why should this not be protected? You will probably experience unanticipated costs of failure, increased energy costs, low performance, and exhaustion if your failure to perform regular maintenance.

2. Ignition Problems

Several causes may increase the ignition problems. When the pilot is dirty, short cycling or a burner may cause the failure of the pilot, a lockout of the furnace, or delayed burner ignition. It may also result from a problem in gas supply or there is a high chance that the ignition component is not working properly and needs to be replaced. In any case, the professional technician will handle these problems because it deals with hazardous elements such as voltage and gas problems.

3. Filters Replacement

The regular replacement of your filter is one of the most important things to extend your furnace life and efficiency. It will restrict airflows if your filter is blocked, which will make it much harder for your unit to circulate in the air. This puts extra pressure on the furnaces’ blower and leads to damage. Also, the furnace can be overheated and shut down due to the dirty or blocked filter.

4. Regular Services

Your heating system is dependent on several mechanical components. The normal wear and tear of these components can have negative effects on your unit performance. These can include a lot of things such as belts and coats that can lead to poor heating, overheating or airflow problems. The stretched belts, oil bearings, and motors maintenance are a part of regular servicing.

5. Unusual Noises are the Warning Sign

Some furnace noises are normal, while others are a warning or a sign that the problem is mechanical related. An engine that is making a squealing sound can indicate that the bearings in the blower motor or inducer motor fail. Also, the motor replacement may be necessary to prevent a failure of the furnace. Perhaps, dirty burners or other airflow issues may result in unusual noises. In any case, these signs should not be ignored because they may be a sign of malfunctioning, or may cause a failure of the furnace.

6. Circuit Tripping Issues

The blower’s overworking may end up tripping the circuit breaker in the furnace.  It is better to keep monitoring the furnace’s airflow to check if it is blocked by something. If the air filter is not clean, the blower will struggle more to push air through it. This increases the energy consumption of the blower can trip the breaker as well.  Check your filter regularly and keep it clean before you reset your circuit breaker.

Perhaps, it is preferable to contact a professional who can determine whether the problem is due to a furnace problem or whether the circuit breaker is working badly. However, other problems may include blocked air registers, duct leaks, or dirty coils.

7. Thermostat Problems

Many thermostats are available, both programmable and non-programmable. Often, if you think that the furnace doesn’t function properly, probably the issue is with the thermostat. You can avoid paying for a costly or unnecessary service call by referring to the owner’s manual and reviewing the operating instructions. Usually, the programmable thermostats have replaceable batteries. If problems are still inoperative, a service technician can quickly diagnose problems.

8. Dirty Evaporator Coils or Condenser

We often neglect the regular maintenance of the air conditioner.  Dirt can block the system’s coils, reduce efficiency significantly. After the condenser is switched off, you can hose off the coil. Also, switch off the power near the condenser or electric panel at the electric disconnection. Well, if the filters are not frequently changed, it may block the indoor evaporator particularly. A dirty evaporator coil or condenser reduces the furnace and air conditioner’s efficiency. Therefore, it may damage the system badly. However, an experienced service technician may clean the extremely dirty coils properly.

9. Furnace Blower Continuously Working

A furnace blower may run continuously for several reasons. Check the fan switch on the thermostat before you call for service. When the thermostat is set to a fan position, the thermostat runs continuously. Usually, it happens if you switch on the fan accidentally.

In the furnace there is a fan relay that turns on your blower when the heat is required; the blower will not shut off if the relay sticks. The furnace has various kinds of protections and limits. If you activate it, the circuit board on the furnace may bring the furnace to cool down. However, if the limit or security does not reset the blower will not switch off. While a trained service technician may examine the problem or repair it.

10. Water Leakage

High-performance furnaces or air conditioners may produce condensation. However, drain pipes ensure adequate water drainage. When the water is blocked or cracked in the drainage lines, it starts leaking from the furnace. Perhaps, you can keep the drain line clean by pouring bleach regularly into it. Also, the collector box might be possible sources of leaks. Contact an expert technician to determine the source of water leak and repair options. However, other reasons for water leakage may include poor maintenance, installation, and poor service procedures.
