If I call for emergency service, how long do I have to wait?

We value our customers, so we try to arrive at your location within one hour, if possible. We know how it is to be without heating and cooling.

How much does a HVAC system cost?

Heating and cooling systems vary in price. A lot is used when pricing a system, such as: location of system, tonnage, SEER ratings, and more. We offer free estimates because we want to give you the correct cost without charging you before we perform any HVAC services.

Are programmable thermostats good for my home?

A programmable thermostat is a great piece of equipment for anyone who spends more than a few hours a day away from home. The thermostats can reduce your energy bills by 15% and the newest ones can even be set from your phone! Think your thermostat might not be working as well as it once was? Check out our page for thermostat installation and repairs.

What is a good temperature for my home in the winter and summer?

This can be answered in two ways, but we need to know what your goals are. If you are looking to be comfortable in your home, you should keep the house at whatever temperature keeps you cool and comfortable. If you are asking what temperatures to leave your house on to save on energy bills, you should put it on 78° in the summer and 68° in the winter.

What is a cracked heat exchanger?

A cracked heat exchanger makes up the main component in your gas furnace. If a heat exchanger has a crack or rusted holes, then your furnace could send carbon monoxide through the duct system and into your house. If you have discovered a crack in your heat exchanger, you might need a furnace replacement. It is important to shut the heating system down immediately and call Unique Air Heating & Air Conditioning for emergency service at (704) 865-7474.

How do I know if I should repair or replace my system?

  • The room stays warm, even though the system is running
  • Water leaks out of the unit
  • The unit won’t turn on
