Frequently Asked Questions About HVAC Companies

What regular maintenance should I do on my HVAC system?

You can perform some simple maintenance tasks on your own to keep your HVAC system running smoothly:

• Change Air Filters: Change or clean your air filters every 1-3 months. Dirty air filters restrict airflow and decrease system efficiency.
• Clear Debris: Keep the area around your outdoor unit clear of debris, leaves, and snow.
• Check Thermostat Settings: Make sure your thermostat is set to the desired temperature and is functioning correctly.

For more complex maintenance, like cleaning coils or checking refrigerant levels, contact a qualified HVAC technician. Schedule annual or biannual maintenance with a reputable HVAC contractor.

What are the signs my air conditioner needs refrigerant?

Low refrigerant levels can cause various problems with your air conditioner:

• Warm Air: The most noticeable sign is that the AC is blowing warm or not cool air.
• Ice Buildup: Ice may form on the AC unit.
• Increased Energy Bills: Your system has to work harder to cool, leading to higher energy consumption.
• Hissing or Bubbling Sounds: These sounds may suggest a refrigerant leak.

If you suspect low refrigerant, contact an AC repair specialist to diagnose the issue and recharge the system.

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