Frequently Asked Questions About HVAC Companies

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

What are the most common HVAC problems?

Common HVAC problems include:

  • AC not cooling: Refrigerant leaks, compressor issues, or thermostat problems.
  • Furnace not heating: Pilot light or ignition control issues, blower motor problems, or clogged filters.
  • Uneven temperatures: Ductwork leaks, inadequate insulation, or faulty thermostats.
  • Poor air quality: Dirty air filters, mold growth in ductwork, or inadequate ventilation.
  • Strange noises: Unusual sounds from the system can indicate a variety of problems with different components.
  • High energy bills: Inefficient systems, ductwork leaks, or improper thermostat settings.
If you're experiencing any of these issues, contact a qualified HVAC technician for diagnosis and repair.

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 without existing ductwork.

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 refrigerant lines or evaporator coil.
  • 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 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.
