Frequently Asked Questions About HVAC Companies

Find answers to common questions about HVAC services, finding contractors, and getting the best heating and cooling solutions for your needs.

What is the difference between an AC unit and a heat pump?

While both air conditioners and heat pumps provide cooling, they differ in how they generate heat. An AC unit cools your home by extracting heat and transferring it outside. It uses a separate furnace or heating system for heating in colder months. A heat pump, however, can both cool and heat. In cooling mode, it functions like an AC, extracting heat from indoor air and releasing it outdoors. In heating mode, it reverses this process, extracting heat from the outside air (even in cold temperatures) and transferring it inside. This makes heat pumps more energy-efficient for heating than traditional electric resistance heating, especially in mild to moderately cold climates.

What are the different types of HVAC systems?

Several types of HVAC systems are available for residential and commercial buildings:
  • Split Systems: The most common type, consisting of an outdoor unit (condenser/compressor) and an indoor unit (air handler/furnace).
  • Heat Pumps: Provide both heating and cooling by transferring heat between indoor and outdoor air.
  • Ductless Mini-Splits: Ideal for homes without existing ductwork or for adding heating and cooling to specific zones.
  • Packaged Units: A single unit that contains all the system's components.
  • Geothermal Heat Pumps: Use the earth's stable temperature to provide highly efficient heating and cooling.
An HVAC professional can help determine the best type of system for your needs and budget.

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 individual temperature control. Ductless mini-splits are more energy-efficient than traditional ducted systems and are a good option for homes where adding ductwork is impractical.

What is the best temperature to set my thermostat in summer?

The best temperature to set your thermostat in summer depends on your personal preferences and how much you’re willing to spend on energy costs. A general recommendation is to set your thermostat to 78°F (26°C) when you're home and awake. You can save energy by setting the thermostat higher when you're away or asleep.

What is the best temperature to set my thermostat in summer?

The best temperature to set your thermostat in summer depends on your personal preferences and how much you’re willing to spend on energy costs. A general recommendation is to set your thermostat to 78°F (26°C) when you're home and awake. Consider a programmable thermostat that allows you to automatically adjust the temperature based on your schedule.
