What is a ductless mini-split system?

A ductless mini-split system is a type of HVAC system that doesn't require ductwork. It consists of an outdoor unit (compressor/condenser) and one or more indoor units (air handlers) connected by refrigerant lines and electrical wiring. Each indoor unit cools or heats a specific zone or room, providing customized comfort. Ductless mini-splits are more energy-efficient than traditional ducted systems and are a good option for homes without existing ductwork.

What type of HVAC system is best for my home?

The best HVAC system for your home depends on several factors, including your:
  • Climate: Heat pumps are generally more efficient in moderate climates, while furnaces are better for colder regions.
  • Budget: The upfront cost of different systems can vary significantly.
  • Energy Efficiency Goals: Higher-efficiency systems are usually more expensive upfront but result in lower energy bills over time.
  • Home Size and Layout: The square footage and layout of your home affect the system's capacity and ductwork requirements.
  • Existing Ductwork: If you have existing ductwork, you'll need a system compatible with it.
A qualified HVAC contractor can assess your needs and recommend the best heating and cooling system for your property.

What are the benefits of a programmable thermostat?

A programmable thermostat allows you to schedule temperature changes throughout the day, lowering your utility bills when you are not at home. This can significantly reduce your energy costs and improve home comfort.
