HVAC FAQs

How Much Is a New HVAC System?

The cost of a new HVAC system will really depend on the brand, make, model, type, and size unit you select. Additionally, how efficient the system is, as well as if any other elements are included, such as smart technology, may impact the price.

What Is a Heat Pump?

A heat pump is a type of HVAC system known for it’s energy efficiency. These systems utilize electricity to effectively transfer heat indoors in the winter and outdoors in the summer. Similar to a ductless system, it can provide both heating and cooling to a home. There are a variety of heat pump systems available, such as ductless heat pumps, geothermal heat pumps, and ducted heat pumps.

What Is a SEER Rating?

A SEER Rating, also referred to as a Seasonal Energy Efficiency Ratio, measures the cooling output of an air conditioning system. It essentially measures how efficient and how much energy a system requires. All residential systems are required to have a SEER rating of at least 13. However, it’s best to consult with a qualified HVAC technician to determine what rating is best for your cooling needs.

What Is CFM in HVAC?

A CFM, or Cubic Feet Per Minute, refers to a calculation specific to airflow. It details how much airflow is required in a space. For example if you live in a large home, there is more airflow being distributed  - this would lead to a higher CFM. Understanding your home’s CFM will give you a better picture of what HVAC system you need for your space.

How Often Should You Service Your HVAC?

You should have your heating and air conditioning systems inspected and maintained at least once a year. It’s typically recommended to have your AC maintained in the spring before summer hits and your heating system in the fall prior to the winter months.

Should I Repair or Replace My HVAC System?

It depends on the problem your system is facing. Some heating and cooling issues can be easily solved through a repair, while other problems may indicate that a replacement is needed. It’s best to consult with a skilled HVAC technician to determine which course of action is recommended. However, if the cost of the repair will be higher than a new system, it’s typically best to just have a new heater or AC installed.

What Is a Condenser?

A condenser refers to the part of your air conditioner which is outside the home and consists of a series of coils. It is responsible for transferring heat outside by converting gas, from the compressor, into a liquid. This is what helps keep your home cool.

How to Tell if Thermostat Is Bad

Your thermostat is an integral part of keeping your home cool in the summer and warm in the winter as it communicates with your HVAC system to achieve the desired temperature you set it too. However, when your thermostat malfunctions, it can wreak havoc on your comfort. 

Your Thermostat May Be Broken If:


  • It is unresponsive to changes in settings
  • Your HVAC system won’t turn on or off
  • The temperature in your home doesn’t correlate with what the thermostat is set too
  • It loses previously programmed settings
  • The temperature in your home keeps changing

What Causes Frozen Evaporator Coils?

Typically, evaporator coils become frozen if there is a lack of necessary air flow. This could be caused by dirty filters or damaged ductwork. A frozen evaporator coil could also be due to issues with your systems refrigerant or a malfunctioning fan, as well as clogged condensate lines.
