Grinding, Squealing and Screeching: Interpreting the Noises Your HVAC Makes

If something is failing or going amiss with your HVAC unit, chances are, your HVAC unit is letting you know something is not quite right. However, most of the cues come in the form of sounds that many of us may overlook. If you hear your HVAC unit grinding, squealing, screeching or squeaking, it is letting you know it needs help. I was unaware of these cues and overlooked them. It ended up costing me a lot of money in repairs. I want to make sure that does not happen to other people, so I made this website. I hope you learn how to interpret the noises your HVAC unit is making so you can get it the repairs it needs before you incur a costly repair, or worse, permanently ruin your unit for good.

Grinding, Squealing and Screeching: Interpreting the Noises Your HVAC Makes

Common HVAC Services Provided By A Professional HVAC Company

by Billie Carlson

Heating, ventilation, and air conditioning are the primary services provided by any HVAC company. These services help to keep your home warm during the winter and cool during the summer.

A poorly maintained HVAC system will lead to increased running costs of up to 30% resulting from it consuming more energy for temperature regulation.

Professional HVAC companies will do the installation, repair, and maintenance of your unit to ensure that it keeps running at optimum capacity. Here's a quick guide on some of the services provided by an HVAC company.

Inspection and Free Estimate

For any HVAC contractor services, an inspection is performed beforehand to determine the type of unit suitable for your home. The HVAC contractor will inspect your home and advise on the most convenient form of heating, ventilation, or cooling, together with the total estimated cost of installation.

Some professional HVAC contractors will provide this inspection service at no cost.

Air Conditioner Cleaning and Maintenance

A coil leak problem could be why your AC unit runs but does not provide enough cool air. An HVAC service provider would inspect your unit for any such leaks and also advise on whether it is time to make a replacement. In response to the leak, the HVAC contractor would recharge the system through constant cycling, which will help prevent any rise in your utility bills.

Some professionals would advise using a new cooling system with a SEER (Seasonal Energy Efficient Ratio) to provide a suitable temperature and keep your electric bills low.

Cleaning and Servicing of Furnaces

Frequent and periodic cleaning of your furnace will help in promoting airflow in your unit. A regularly cleaned and serviced furnace will help eliminate any potential heating problems in your home during cold seasons. 

The air filters in the furnace must be cleaned to remove traces of dirt or dust. Accumulated dust particles will result in a block of the airflow, leading to your unit's reduced efficiency and consequently an increase in the utility bills.

A professional and licensed HVAC contractor will regularly clean and maintain your furnace for you.

Energy Audit

To prevent your home from accumulating outrageous utility bills, an energy audit is prudent in testing whether your unit is efficiently running. An HVAC contractor would inspect your equipment for heat loss, heat gain, energy efficiency, and proper ventilation.

Install Programmable Thermostat

An efficient way to save on energy is through a programmable thermostat that automatically turns itself on and off when someone enters or exits the room.

An HVAC company will install this device to save you money on heating or cooling bills while you are away.

Conclusion

Before you engage any HVAC contractor for the above services, ensure that they are licensed and have the proper HVAC certification.
