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 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.

Should I repair or replace my old furnace?

Deciding between repairing or replacing your furnace depends on
  • Age: Furnaces typically last 15-20 years. If yours is significantly older, replacement is often the better overall choice.
  • Frequency and Cost of Repairs: If you've been having frequent or expensive repairs, replacing the furnace might be more cost-effective in the long run.
  • Energy Efficiency: Newer furnaces are significantly more energy-efficient, which can lead to lower energy bills.
  • Safety Concerns: Older furnaces can pose safety risks, such as carbon monoxide leaks. A new furnace offers enhanced safety features.
Consult with a trusted HVAC professional to assess your furnace and get recommendations.

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.

Deciding between repairing or replacing your furnace depends on
  • Age: Furnaces typically last 15-20 years. If yours is significantly older, replacement is often the better long-term choice.
  • Frequency and Cost of Repairs: If you've been having repeated repairs, replacing the furnace might be more cost-effective in the long run.
  • Energy Efficiency: Newer furnaces are significantly more energy-efficient, which can lead to lower energy bills.
