HVAC Maintenance Services

When the Den-Son team performs maintenance services for your heating or cooling system, we work our way through a complete checklist. Here’s what to expect from an HVAC tune-up:

  • Inspect electrical connections: Many HVAC components rely on electricity to run efficiently. We’ll test the connections to ensure that they receive the appropriate voltage, and we’ll advise you about any necessary repairs or replacements.
  • Refill refrigerant: Your cooling system relies on refrigerant to keep your home comfortable during the summer months. We’ll refill this fluid as necessary and ensure that it’s at the optimal level for the cooling system.
  • Lubricate moving parts: Every HVAC component is composed of numerous moving parts, and the system’s performance suffers if each part doesn’t move efficiently. We’ll lubricate moving parts to prevent friction and overheating.
  • Calibrate system: For optimal comfort, your HVAC system must work together with your thermostat. Our technicians will calibrate the thermostat so that your home’s temperature and relative humidity level are as accurate as possible.

HVAC Maintenance Agreements

When was the last time you scheduled an HVAC tune-up? Our technicians can perform a one-time inspection, but it may be in your best interest to opt for a maintenance agreement instead. Our Preferred Customer Maintenance Agreement includes annual heating and AC maintenance services for your systems, along with priority emergency repairs should you need them.

We also offer discounts on HVAC parts, which can help to keep your costs manageable if you need a replacement part or a new system.
