Frequently Asked Questions

How long does a mini split installation take?

Most single-zone ductless mini split installations are completed in 4 to 8 hours — often in a single day. Multi-zone systems or more complex configurations may take a full day or spread across two visits. We'll give you a clear timeline upfront so you can plan accordingly.

Do I need ductwork to install a mini split system?

No — that's one of the biggest advantages of ductless mini split systems. They require only a small 3-inch hole through an exterior wall to connect the indoor and outdoor units. This makes them ideal for older Plaistow homes, room additions, garages, and any space without existing ductwork.

Can a mini split system also heat my home in winter?

Yes! Modern mini split systems operate as heat pumps, providing efficient heating even in below-freezing New Hampshire winters. Many of today's cold-climate models are rated to operate efficiently down to -13°F, making them an excellent year-round solution for Plaistow homeowners looking to reduce heating costs.

What brands of mini split systems does Big Al's install?

Big Al's Services installs and services all major ductless mini split brands including Mitsubishi Electric, Daikin, LG, Fujitsu, and more. We'll help you choose the right brand and model based on your home's layout, efficiency goals, and budget — with no brand bias, just honest advice.
