Appliance and AC Repair FAQs

1. What does “HVAC” mean?

HVAC stands for heating, ventilating, and air conditioning. The term describes the products that keep the indoors comfortable. Accordingly, the primary purpose of HVAC systems are to provide thermal comfort and to maintain good air quality. People commonly refer to HVAC systems as using different terms such as air conditioners, air conditioning, A/C, AC, heaters, or heating systems. When your HVAC unit is not running properly you may notice hot air, no air, or fans not running. Therefore, any of these issues require an ac repair.  

2. How often should air filters be replaced?

All of the air that travels to your home or business must first pass through the system’s air filter. In a point often overlooked, people forget that dirty air filters can worsen allergies and other ailments. Without a doubt, the EPA recommends home owners should check their filters every month. Especially during periods of heavy use, such as the summer months. At a minimum, the EPA recommends changing filters at least every three months. In fact, by changing the filters on a regular basis, you decrease the chances of needing an ac repair.

3. How often should you call for air conditioning service?

Preventative maintenance improves the efficiency of your HVAC system. Generally, the EPA recommends have cooling systems serviced by a professional HVAC contractor at least once each year. Check our coupons page or call 702-877-100o to check current specials seasonal discounts!

  • Fan not running 
  • Compressor not running

5. When should I replace my air conditioning system?

Experts recommend that consumers consider HVAC replacement for equipment over ten years old. In particular, modern systems are up to 50 percent more energy efficient than those made just a decade ago. Not surprisingly, cooling systems that require expensive repairs or that simply aren’t keeping you comfortable are also good candidates for replacement. We offer professional installation on new HVAC units. Check our coupons page or call 702-877-100o to check current specials!

6. What do the terms “SEER” and “EER” mean?

The HVAC industry uses standard to rate the energy efficiency of cooling products. The seasonal energy efficiency ratio (SEER) compares the system’s cooling output over the entire cooling season against the energy that the system consumes. Since 2006, central ac systems installed in the United States are required to have a SEER rating of at least 13. Energy Star qualified products must have at least a 14 SEER rating.

The energy efficiency ratio (EER) is similar to SEER ratings, but instead of comparing cooling output to energy consumption of a specific season, EER ratings reflect the system’s efficiency during peak operating usage. The EER rating must be at least 12 to qualify as an Energy Star product. 

7. Why are air conditioners sized by the ton?

The cooling capacity of an air conditioner is measured by the amount of heat that the system can extract from the environment, as measured in British Thermal Units (BTUs). Interestingly, the term “ton” refers not to weight, but to the amount of BTUs that it takes each hour to freeze one ton of water over a single 24-hour period, which is 12,000 BTUs. Generally, one ton of cooling capacity is required for every 600-square-foot area.

8. How does my cooling system move air through my home?

HVAC work by using freon to take heat from the air as a fan pulls household air over the unit’s coils. To complete this, an air handler moves the cooled air through ductwork to supply vents in conditioned spaces. Return grills draw air back through the air ducts to the coil where the air cycle continues until the temp set on the ac system’s thermostat is reached. When any of these components do not work, the unit will not cool properly. As a result, you will require a qualified technician to perform an AC repair.
