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 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 HVAC technician to diagnose the issue and recharge the system.

Should I repair or replace my old furnace?

Here are some factors to consider when deciding whether to repair or replace your furnace:
  • 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.

What regular maintenance should I do on my HVAC system?

You can perform some simple maintenance tasks yourself 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.
