HVAC Services

HVAC systems are one of the most important inventions of all time. No matter how hot or cold it gets outside, your HVAC works tirelessly to maintain home comfort.

Even with proper care and maintenance, your HVAC can develop problems. If your HVAC is acting up, give us a call. We will get to the root cause of the problem and treat it before it snowballs into a major concern.

With proper care and maintenance, an HVAC can last around 15 years. If your HVAC is on its last legs, replacing it would be a better option than repairing it.

Thinking of replacing your AC? Before you make a decision, let us inspect your unit. We recommend replacing an AC only after we have exhausted all repair options.

AC Problems We're Equipped For Include:

  • Refrigerant leaks
  • Unclean condenser coils
  • Frozen evaporator coils
  • Clogged drain line
  • Faulty motors

We will only suggest AC replacement if the system is on its last legs or damaged beyond repair, and repair and other costs outweigh the benefits of the unit.

Planning to install a new AC? You can trust us to manage your project from start to finish. We have extensive experience managing air conditioning installation and repair projects of varying complexity near Windsor.

The Importance of Regular HVAC Tune-ups

Your HVAC is one of the most hardworking equipment in your home. Like all other household equipment, HVACs require proper care and maintenance. Periodic maintenance extends system lifespan, improves performance, and minimizes equipment breakdowns.

Lack of maintenance can affect HVAC efficiency. A neglected system is unreliable and requires frequent repairs. A low-efficiency HVAC has to work harder and longer to meet your home’s heating and cooling requirements.

An overworked system can get stressed and develop problems. In a worst-case scenario, an unaddressed problem can snowball into a major issue and your HVAC might go kaput.

You can avoid the following problems with periodic maintenance:

  • Airflow problems
  • Short cycling
  • Bad compressor
  • Clogged/damaged filters
  • Drainage problems
  • Refrigerant leaks
  • Unclean condenser and evaporator coil

During a tune-up, our team will:

  • Inspect and clean or change air filters
  • Clean the condensate drain
  • Inspect the outdoor unit
  • Check electrical connections
  • Lubricate moving parts to reduce friction between them
