WHAT IS A

Q: What is "HVAC"?
A: HVAC is a system that provides different types of heating and cooling services to residential and commercial buildings.
Q: What is "ENERGY STAR"?
A: The ENERGY STAR logo is a small blue and white logo that is placed on items that meet superior energy efficiency standards. This label provides an easy way for consumers to identify quality, high-efficiency products.
Q: What is a "Heat Pump"?
A: A heat pump is an all-in-one heating and air conditioning system that works year-round to keep you comfortable. In colder weather, the heat pump pulls the heat from the cold outdoor air and sends it inside to warm your home.
Q: What is an "Air Handler"?
A: An air handler is a large metal box that contains a blower, heating or cooling elements, filter racks or chambers, sound attenuators, and dampers. It usually connects to a ductwork ventilation system that distributes the conditioned air through the building and returns it to the AHU.
Q: How does a "Ductless Split System" work?
A: A ductless split system can be used to replace a traditional central ducted system or to supplement it. It uses an outdoor condensing unit, indoor air handler/evaporator (fan coil), and refrigerant line sets to transfer cooled or heated air to individual rooms as needed.
Q: What is "Two-Stage Heating"?
A: Two-stage heating means the furnace has two levels of heat output: high for cold winter days and low for milder days.
Q: What is a "Thermostat"?
A: A thermostat is a temperature-sensitive device that controls and regulates the temperature in a space for systems such as a furnace, air conditioner, or both. When the indoor temperature drops below or rises above the thermostat setting, the device initiates or terminates either the heat or cooling modes, depending upon the thermostat setting and temperature set point.
Q: What is "Indoor Air Quality"?
A: Indoor air quality is important for our health and comfort.
Q: What is the difference between "UV Air Purifiers" and air filtration?
A: – UV Air Purifiers are more effective at removing airborne germs, bacteria and mold than air filters.
Q: What is "Air Purification"?
A: The Blueair Classic 405 Air Purifier is an excellent choice for people with allergies or asthma. It is also a great choice for people who want to improve the air quality in their home.
Q: What is a "MERV Rating"?
A: MERV is a rating system that allows consumers to compare the performance of one filter to another. The higher the MERV rating, the more particles - dust mites, pet dander, air allergens, etc - your filter will remove from the air.
Q: What does "MERV" mean?
A: MERV is a filter rating system devised by the American Society of Heating, Refrigeration and Air conditioning Engineers (ASHRAE) to standardize and simplify filter efficiency ratings for the public. The higher the MERV rating, the higher the efficiency of the air filter. Simply stated, a MERV 12 filter will remove smaller particles from the air than a MERV 8 filter.

AIR CONDITIONER

Q: How does an air conditioner work?
A: The refrigerant in an air conditioning system helps to cool and dehumidify the inside air. The system uses an outside fan to pull air across the external parts of the system to cool and condense the refrigerant.
Q: What maintenance does a UV Air Purifier require?
A: A UV air purifier is a great way to improve your indoor air quality. They are low maintenance and can help to remove harmful airborne contaminants from your home.
Q: What air temperature should my air conditioner produce?
A: The air coming out should be 15°-20° below the temperature of the air coming in.

A DUCTLESS MINI

Q: What makes up a ductless mini split system?
A: Ductless mini split systems are composed of an indoor air handler/evaporator (fan coil), and outdoor condensing unit and an approximate 2.5-3" conduit that accommodates the power (wiring), refrigerant line sets and a PVC condensate line (drain).
Q: How noisy is a ductless mini split?
A: Ductless air handlers are very quiet and are similar to whispering in a library. The outdoor units are less quiet but are still much quieter than a conventional air conditioning condenser.
Q: Why does my heat pump system sometimes freeze up?
A: There are several factors that can cause system freezing. First, if running in the cooling mode check your filters; restrictions in air flow can lead to freezing. Next, thaw the system out by turning off the cooling and running the fan. Also, try turning the system to the heat mode until the ice has melted. If the problem recurs after checking for air restrictions and thawing your system thawed, schedule a service call.
