Central split systems combine indoor equipment, an outdoor unit, and ductwork to cool the property. Tell us which part of the system is showing symptoms, and whether the issue affects every room.
When your system needs attention
- Air is moving, but it does not feel cool.
- Some rooms are comfortable while others stay warm.
- The system runs longer than expected.
- You notice water around indoor equipment or a drainage problem.
You don’t need to know the cause before contacting us. Tell us what you’ve noticed, and we’ll discuss the next step.
Installation and replacement
For a replacement or new installation, the property layout, existing ducts, and equipment compatibility all matter. We can discuss the current setup and the areas you want to cool before defining the work.
Discuss an installationRepairs and troubleshooting
Warm air can have several causes. A visit helps distinguish airflow, electrical, drainage, and refrigeration issues. Describe what you notice, including whether the indoor and outdoor units run.
Maintenance for the season ahead
Our AC maintenance checklist covers refrigerant-charge checks, applicable capacitor testing, drainage, coil cleaning, and a new one-inch filter. Read the maintenance page for details and discuss system-specific requirements with us.

Let’s talk it through.
Can central AC be added to an existing property?
That depends on the property, available space, and existing ductwork. Contact us to discuss your setup. Ductless mini-splits may also be worth discussing where ductwork is limited.
Why is one room warmer than the others?
Room exposure, airflow, ducts, and the cooling setup can all play a role. Include which rooms are affected and whether the problem is new.
Can I arrange maintenance before summer?
Yes. Choose maintenance on the request form and include your town and system details. The team will follow up about the work and scheduling.
