Our Comprehensive AC Services

Central AC Installation and Replacement

Central air conditioning units have an expected lifespan of 10 to 15 years. The quality of installation determines how well your system performs during that time. Our AC installation experts will assess your home's cooling needs, considering things like square footage, ductwork layout and insulation levels. Based on our findings, we'll help you choose a new system that can efficiently cool your space.

As a premier dealer for major brands like Trane, Daikin and Goodman, we can help you access some of the most efficient central AC units and manufacturer warranties that protect your investment. Our technicians are trained on the best installation practices for all systems we install to ensure efficient operation from the start.

We also replace AC units that have exceeded their lifespan. Signs it may be time to replace your central air unit include:

  • Frequent repairs
  • Sudden spikes in energy bills
  • Uneven cooling
  • Unusual noises
  • Poor humidity control

If you're not sure whether your current system needs a simple repair or replacement, we'll assess it and explain your options so you can make the right decision.

Planning around a budget? Qualified homeowners can take advantage of flexible financing through Optimus, making it easier to invest in a new high-efficiency cooling system.

Professional Repairs for Home AC Units

We help homeowners deal with common AC problems like:

  • Short cycling, or turning on and off without reaching the set temperature
  • Uneven cooling
  • Unusual noises
  • Weak or no airflow
  • Warm air from vents
  • Water puddles or leaks
  • Sudden spikes in energy bills with the same usage

These signs usually warn you of underlying problems before the system stops working. A single symptom could indicate one of several issues. For example, if your AC runs constantly but won't cool the house, the issue might be a refrigerant leak or something simple like a thermostat reading the wrong temperature.

Fixing problems on the surface rather than at the root often leads to even more damage to the unit — and repeated service calls. That's why our AC repair technicians perform thorough assessments before recommending any repair. Once the diagnosis is complete, we walk you through what's actually wrong, why it happened and what needs to be done to fix it properly.
