What is a heat pump?
A heat pump is a central air conditioning system that also heats your home in during the winter season. The term 'heat pump' comes from the unit pumping heat out of the house for cooling and into the house for heating.

Why is the right system size so important?
Getting the right HVAC system size for your home is quite important. A system that is too large for your home will not adequately remove moisture from the air, leaving an unwanted sticky feel during the summer and a fresh from the oven feel in the winter. A system that is too small for your home will constantly start and stop, causing itself to overwork and wear out more quickly.

Heating FAQS

Why won't my pilot light stay lit?
You may have a dirty pilot or bad thermocouple. The best solution is to call AirMaster to have this checked and serviced.

The burner comes on and only stays on 1 minute, then goes off.
The most common solution for this is to check your thermostat and make sure that it is set to the correct temperature. If the temperature is set to a comfortable degree, then the filter or the thermostat's heat anticipator is dirty and needs cleaning.

The burner comes on, but the fan doesn't.
This problem is usually due to a bad fan motor or fan control.

My furnace won't come on and the pilot is on.
Check the thermostat and breakers or fuses to make sure that there is not an electrical problem.

The furnace runs but goes off before it gets up to temperature.
Check thermostat, it could be out of calibration.

Cooling FAQS

The air conditioning unit is not turning on.
Check the thermostat and breakers

The AC unit is running, but is not properly cooling the house.
Check filters on furnace or air handler and clean condenser coil on outside unit.

The inside coil on furnace freezes up
Check filter on furnace or air handler and check if motor is running.

It's 95 degrees outside, and my AC is constantly on.
Your AC unit is designed to run constantly when the outside temperature is greater than 95 degrees.

I just turned on the air conditioner after coming home, and the temperature has not changed at all. What's wrong?
If you turn the AC on in the afternoon when it is hot, it could take 3 or 4 hours or more to cool the air inside the house.

Water is running out of coil on furnace down through furnace.
Check condensate drain to see if it is plugged up.

My AC runs all the time and doesn't cool and filter is clean and condenser coil is clean.
Call AirMaster to diagnose and service your air conditioner. The unit could be low on freon or compressor isn't pumping.

The blower on furnace runs but outside unit doesn't run.
Check thermostat to see it is calling for cooling. Check breaker for unit and check disconnect switch outside.

The outside unit runs but fan on furnace doesn't
The problem could be a bad blower motor or blower relay. Call AirMaster for service to your unit.

The blower inside or unit outside doesn't run and thermostat is set right and breakers oar on.
Call AirMaster for service. It could be a bad transformer in furnace or air handler.

Terms to Know:

Advanced Reciprocating Compressor
Type of compressor that uses a more efficient process for compressing refrigerant for better cooling efficiency.

AFUE
Annual Fuel Utilization Efficiency. Indicated as a percentage, your furnace's AFUE tells you how much energy is being converted to heat. For example, an AFUE of 90 means that 90% of the fuel is being used to warm your home, while the other 10% escapes as exhaust with the combustion gases.

BTU
British Thermal Unit. Used for both heating and cooling, BTU is a measure of the heat given off when fuel is combusted. Or for cooling, it's a measure of heat extracted from your home. One BTU is equal to the heat given off by a wooden kitchen match.

Capacity
The ability of a heating or cooling system to heat or cool a given amount of space. For heating, this is usually expressed in BTUs. For cooling, it is usually given in tons.

Compressor
Part of a split-system heat pump or air conditioner's outdoor unit that controls the pressure applied to the refrigerant, necessary for taking in heat to warm your home or getting rid of heat to keep your home cool.

Condenser Coil
Part of the outdoor portion of a split-system air conditioner or heat pump. By converting refrigerant that is in a gas form back to a liquid, the coil sends heat carried by the refrigerant to the outside.

Damper
A type of "valve" used in duct work that opens or closes to control airflow. Used in zoning to control the amount of warm or cool air entering certain areas of your home.

Downflow
A type of furnace that takes cool air from the top and blows warm air to the bottom-common where your furnace must be located in a second-floor closet or utility area.

Electronic Air Cleaner (EAC)
An electronic device that filters out large particles and contaminants in indoor air. It then electronically pulls out tiny particles that have been magnetized, such as viruses and bacteria, drawing them to a collector plate.

Load Estimate
A series of studies performed to determine the heating or cooling requirements of your home. An energy load analysis uses information such as the square footage of your home, window or door areas, insulation quality and local climate to determine the heating and cooling capacity needed by your furnace, heat pump or air conditioner. When referring to heating, this is often known as a Heat Loss Analysis, since a home's heating requirements are determined by the amount of heat lost through the roof, entry ways and walls.

Evaporator Coil
Part of a split-system air conditioner or heat pump located indoors. The evaporator coil cools and dehumidifies the air by converting liquid refrigerant into a gas, which absorbs the heat from the air. The warmed refrigerant is then carried through a tube to the outdoor unit (condenser coil).

Fan Coil
An indoor component of a heat pump system, used in place of a furnace, to provide additional heating on cold days when the heat pump does not provide adequate heating.

HVAC
Term used for Heating, Ventilation, and Air Conditioning

HSPF
The Heating Seasonal Performance Factor is a measure of the heating efficiency of a heat pump. The higher the HSPF number, the more efficiently the heat pump heats your home.

Horizontal Flow
A type of furnace, installed on its "side," that draws in air from one side, heats it and sends the warm air out the other side. Most often used for installations in attics or crawl spaces.

Humidifier
A piece of equipment that adds water vapor to heated air as it moves out of the furnace. This adds necessary moisture to protect your furnishings and reduce static electricity.

Matched System
A heating and cooling system comprised of products that have been certified to perform at promised comfort and efficiency levels when used together, and used according to design and engineering specifications.

Operating Cost
The day-to-day cost of running your home comfort equipment, based on energy use.

Payback Analysis
Overall measure of the efficiency and value of your home comfort system. By combining your purchase price and ongoing operating costs, a payback analysis determines the number of years required before monthly energy savings offset the purchase price.

Perfect Heat T
The Perfect Heat gas furnaces use a two-stage valve and patented control algorithm allowing the furnace to more closely meet the heating needs of the home. A Perfect Heat heat pump controls the airflow across the indoor coil and controls auxiliary heater banks to deliver warmer, more comfortable air to the home. In both cases the end result is even, consistent heating.

Perfect Humidity T
Perfect Humidity will remove an amazing amount of moisture from indoor air to help eliminate that warm, sticky, uncomfortable feeling you get in high humidity. Add a humidifier and the system provides Perfect Humidity in heating.

PuronT Refrigerant
Puron is an environmentally sound refrigerant designed to protect the earth's ozone layer. Federal law requires all manufacturers phase out ozone depleting refrigerants in the next few years. Puron is approved by the US Environmental Protection Agency as a replacement from Freon 22*.

Reclaiming
Returning used refrigerant to the manufacturer for disposal or reuse.

Reciprocating Compressor
A type of compressor used in air conditioners that compresses refrigerant by using a type of "piston" action.

Recycling
