Sound familiar?
If any of this is happening, it is worth a call
You do not need to know what failed. Describing the symptom is enough to get a real answer on the phone.
- Garage or workshop you want to actually use in August
- Addition or converted space with no duct run
- Bonus room over the garage that never cools
- Master bedroom that runs hot while the rest of the house is fine
- Florida room or enclosed porch
- Home office or detached studio
What the visit includes
The part most quotes leave out: what you actually get
Four things that separate a proper job from a parts swap. All four happen on every call.
Sized for the room, not the catalog
An oversized mini-split short cycles and leaves the room humid. Capacity is matched to the actual load of that specific space.
Clean line set routing
Penetrations sealed, line hide used where it is visible, condensate routed so it never becomes your problem later.
Single and multi-zone
One head or several off one outdoor unit, depending on what the space and the budget call for.
Serviced after the sale
Mini-splits need their blower wheels and drain pans cleaned. That is included in maintenance visits — many installers never mention it.
Questions
Ductless Mini-Splits, answered plainly
Can a mini-split heat as well as cool?
Yes. Nearly all modern mini-splits are heat pumps and handle Northeast Florida winters comfortably.
How loud are they?
The indoor head is typically quieter than a refrigerator. The outdoor unit is quieter than a conventional condenser.
Can you add one to my existing system?
A mini-split is fully independent — it does not tie into your existing ductwork or air handler, which is exactly why it works for problem spaces.
