Benefits of HVAC Maintenance and Repair

If your HVAC system stops working, you know to call Blue Dot for service. However, you may not know that there are plenty of reasons to schedule regular maintenance well in advance of any repair needs. Taking care of your system is a task you should plan for at least once or twice a year. If you do, you can enjoy the following benefits:

  • Longer lifespan for the equipment
  • Better efficiency from the unit
  • Lower utility bills
  • Ability to find faults before they completely break down
  • Better indoor air quality
  • Improved function from each component
  • Peace of mind that your HVAC system is in top condition for the season

If you worry that you might forget to schedule maintenance, you have a great reason to consider signing up for a maintenance plan. With a maintenance plan, you can schedule service around your commitments, whenever it is convenient for you. In addition, maintenance plan membership can give you extra benefits, such as discounts on repairs or priority service.

When to Call for HVAC Repairs

Your HVAC system is designed to operate mostly independent of you. When it starts to have problems, it often gives you several warning signs. If you’re an attentive property owner, you might notice them while the system is still functioning. Here are some signs that you need to schedule residential or commercial HVAC repair.

Inconsistent Cooling or Heating

Your system should work accurately every single time, and it should maintain the right temperature for each room. Inconsistency throughout the building or during the day is an indicator of trouble. All air conditioners should be able to keep up, even on the hottest days. If yours doesn’t seem to be up to the task, it might be undersized or need repair.

Weak Airflow

The system relies on a blower to deliver the conditioned air to various rooms. If the airflow is low or producing only room-temperature air, you need a prompt fix. Weak airflow is likely to result in other problems for your home, so it’s important to schedule repair as soon as possible.

Unusual Sounds

Any heating system makes a small amount of noise while it runs, but there are noises that you shouldn’t hear during operation. Clanking, grinding, screeching or banging sounds aren’t normal. They may indicate that a part is wearing out and causing damage to the rest of the system.

Leaking Water

The heating and cooling processes typically generate some condensation that normally drains away. If any part of your system is leaking, you need immediate repairs to protect the components and your electrical system.
