What do homeowners ask about ductless mini-split installation?

How much does a ductless mini-split cost installed in San Diego?

Heat Pro SD does not set prices or equipment life. Ask the licensed independent HVAC pro for an itemized written quote and the manufacturer documents for the proposed equipment.

Do I need a permit for a mini-split installation in San Diego?

Ask the licensed independent HVAC pro what the city or county requires for your scope. Heat Pro SD does not pull permits. Mechanical and electrical permits are common when new equipment or a new circuit is involved, but the contractor confirms that at the address.

Can a mini-split heat as well as cool?

Yes. A heat pump mini-split moves heat in both directions. Whether it can heat your house without backup depends on the published capacity at the outdoor temperatures your address actually sees. Ask the contractor for that number. Coastal nights are a different question than Alpine, Ramona, or Julian.

Will a mini-split work in the coastal marine layer?

Yes, but salt air accelerates outdoor coil corrosion. Your crew selects units with coated coils and stainless fasteners for coastal installations in communities like Encinitas, Carlsbad, and La Jolla.

How long does a ductless mini-split last?

Ask the licensed independent HVAC pro and the manufacturer documents for the proposed equipment. Heat Pro SD does not publish a typical lifespan.
