  • Improve Insulation: Add insulation to your attic, walls, and floors to reduce heat transfer and improve your home's energy efficiency.
  • Use Window Coverings: Close curtains or blinds during the day to block out sunlight and prevent heat gain.
  • Zone Your HVAC System: If you have rooms that are rarely used or require different temperatures, consider zoning your system to efficiently cool specific areas.

What are the different types of AC units?

Here are some of the most popular types of air conditioning systems:
  • Central AC Units: These systems use a network of ducts to distribute cooled air throughout the entire home or building. They are a common choice for larger homes or commercial properties.
  • Ductless Mini-Splits: Ductless mini-splits provide zoned cooling to individual rooms. They allow for personalized comfort levels.
  • Window AC Units: These units are designed to cool individual rooms and fit into a standard window. They are relatively inexpensive but lack the efficiency and quiet operation of other models.
  • Portable AC Units: Portable AC units offer a flexible cooling solution for single rooms. They require a window for venting.
  • Heat Pumps: Heat pumps provide both heating and cooling, using heat from the air to provide year-round comfort. Heat pumps are ideal for climates with mild winters.
  • Geothermal Heat Pumps: Geothermal heat pumps use the constant temperature of the earth for highly efficient heating and cooling. Though expensive to install, their operating costs are quite low.
The best system for your home or business will depend on various factors, so consulting with a qualified HVAC technician is highly recommended.

What is a heat pump, and how does it work?

A heat pump is an HVAC system that can both heat and cool. It extracts and moves heat between the indoor and outdoor air. In cooling mode, the heat pump works like an AC unit, just like a traditional air conditioner. In the winter, it reverses this process, effectively moving heat from outdoors to indoors to heat your space. A heat pump could reduce your utility bills while providing year-round comfort.

What should I do if my AC breaks down?

If your AC breaks down, follow these steps::
  • Check for Obvious Issues: See if there are any easy fixes, like a clogged filter or power outage.
  • Turn Off the Unit: If you can't identify an easy solution, turn off your AC unit at the thermostat to prevent further damage.
  • Contact a Qualified HVAC Technician: Call a reputable HVAC repair company to diagnose the issue and provide repair options. If it's an emergency, contact an emergency HVAC service.
  • Document the Problem: If possible, note the specific symptoms and take photos or videos of the problem to show the technician.
  • Prepare Questions: Make a list of questions for the technician to ensure you understand the problem, repair options, and costs.
Preventative HVAC services reduce the risk of emergency breakdowns. Consider scheduling an annual tune-up with an HVAC contractor to keep your AC unit in top condition and avoid future breakdowns.
