Your HVAC system is essential to staying comfortable in your home. If you have questions, you aren’t alone. Here are some of the most frequently asked questions from our customers at DTC Texas to help you manage your HVAC system more effectively.

What Does HVAC Stand For?

HVAC stands for Heating, Ventilation, and Air Conditioning. These systems provide temperature control and improve indoor air quality. Our HVAC technicians install, maintain, and repair your heating and AC systems in Georgetown and the surrounding areas.

How Do HVAC Systems Work?

Your heating and cooling systems condition your indoor air and circulate it throughout the space. Your HVAC system filters out dirt, dust, and other particles. Conditioned air is distributed throughout your home via ducts, vents, or registers.

How Often Will I Need a New HVAC System?

Whether you have an AC, furnace, or other HVAC unit, the length of time it lasts depends on many factors. A well-maintained system typically lasts at least 10 years. Your system will also benefit from HVAC tune-up services that keep it performing at peak efficiency. Ask our representatives about which maintenance plans would work best for you.

Does My HVAC System Need Repairs?

There are numerous signs your HVAC system requires service. Look for the following symptoms and give us a call to determine whether there’s an issue with your heating and cooling system:

  • Loud Noises: If your heater or AC makes louder noises than usual, contact us to determine the source. It could be a loose belt or damaged component.
  • Strange Odors: If you notice moldy or burning smells coming from your cooling or heating system, turn the system off and contact an experienced HVAC technician right away.
  • Doesn’t Maintain Temperature: Does your system maintain an even temperature throughout the home. If not, your HVAC system may need attention.
  • Anything else that seems out of place.

If your system acts differently than normal or fails to keep your home comfortable, our team will evaluate the situation and give you an upfront quote on any repairs needed.

How Often Should I Put in a New Filter?

Although we recommend checking your air filter every month, you only need to change it when it becomes clogged or dirty. For most families in our service areas, that’s about once every three months. If you need help determining whether to change your filter, we can help.

What Is an HVAC Tune-Up?

An HVAC tune-up provides essential care for your heating or cooling system. When you choose a maintenance plan, our technicians will inspect both the indoor and outdoor units. The tune-up includes cleaning and lubricating all components of the system. This can prolong the life of your unit and save you money on your energy bills.

How Can I Improve My HVAC Energy Efficiency?

If you can do so without becoming uncomfortable, consider adjusting your thermostat a bit higher in the summer and lower in the winter. You can also invest in a programmable thermostat that can automatically adjust the temperature depending on your criteria.
