Quallet HVAC - About HVAC Products and Services

What is HVAC?
Simply put, HVAC stands for Heating, Ventilation and Air Conditioning. In other words, the services and devices that keep our home cool in the summer, and warm in the winter. Technology has brought us a long way from using a fire place for heat and opening windows for cooling. Today HVAC equipment is more energy efficient than ever, and new technologies such as tank less water heaters, high efficiency heat pumps, and geo-thermal systems are quickly becoming a reality for today's homeowner.

Air Conditioning
A typical household air conditioner consists of an outdoor unit (the coil, condenser and evaporator) and an indoor unit (the air exchanger, which connects into your existing duct work). New systems are pushing the bounderies of quiet operation (as low as 68 dB) and high efficiency (as high as 20 SEER and 14.5 EER). If you're using extremely inefficient window units, or you have an older air conditioning system that's not keeping your cool, it's time to call Quallet HVAC to let our skilled technicians evaluate your current HVAC equipment and cooling needs.

Air Conditioning / Mini-Split Systems
An alternative to your typical central air conditioning system is a ductless or mini-split system. These units have one or more smaller outdoor units connected to wall mounted units inside your home. With a mini-split system, you put the cooling (and heating!) in the rooms that you use it most. Why pay to constantly cool and heat empty rooms in your home? A mini-split system can save you hundreds, or even thousands on your electric bill with efficiency ratings (27 SEER and up!) that your typical central air conditioning system can't even come close to!

Furnaces and Boilers
In a traditional forced hot air, or hot water radiator heating system, the furnace or boiler is what provides the heat. In a furnace, natural gas is burned and the resulting warm air is passed through the heat exchanger which warms the air that is then blown thorough your ducts and into your home. Cold air is brought into the furnace via your return vents.

With a hot water radiator system, gas or oil is burned to heat water, which is then pumped through radiators in your home to provide warmth. Heated water can also be pumped through radiant floor heating, which is installed under the flooring in your home.

HVAC Zone Control
An HVAC zone is an area that a thermostat controls the temperature for. If your home has one thermostat in it, you probably have a single zone. This means that you're heating or cooling your living room, dining room and kitchen while you're sleeping, and your vice versa when you're awake. A properly zoned system will have two or more thermostats controlling two or more zones so you can set a comfortable temperature for where you are, and save money by not providing heating and cooling to areas of your home where you're not spending time. Some homeowners claim a 30% savings in their heating and cooling operation costs after installation of an HVAC zoning system.

Heat Pumps
When you think of heating and cooling your home, you probably envision an air conditioner and a furnace - but not a heat pump. Simply put, a heat pump moves heat from one location to another. In warm months, it can move the heat from inside your home to out, and then the reverse when it's cold outside. One of the biggest advantages of a heat pump over a standard heating ventilating and air conditioning (HVAC) unit is that there's no need to install separate systems to heat and cool your home. Heat pumps also work extremely efficiently, because they simply transfer heat, rather than burn fuel to create it.

The thermostat(s) in your home tell your heater or air conditioner when to turn on and off, based on the desired temperature that you set. Older, dial type thermostats let you set on temperature, and if you left it set while you went to work... you just paid to heat or cool your house all day. Modern electronic thermostats can save you money because they allow you to set multiple times for heating and cooling to be on or off each day, depending on the day of the week. This way you can "set it and forget it" and not pay for heating and cooling when you're not at home.

Water Heaters
Traditionally a tank style water heater has an insulated tank of 40 or 50 gallons that is kept hot by a gas or electric heat source. When you turn on a hot water faucet, water from this reservoir is sent to that faucet and mixed with cold for the desired temperature. Lifespan on a typical tank water heater is 8-10 years. Failure of a hot water heater can be gradual, or catastrophic (imagine you're away and your tank goes, dumping 50 gallons of water in your basement - and the refill line that tries to keep your tank full runs until you realize you have a foot of water in the house!
Within the last few years, tank less style water heaters have started to catch on. Instead of paying to keep a supply of water heated all of the time, a tank less water heater heats water "on-the-fly". When you open a hot water faucet, the unit is triggered and a heating element kicks on to instantly heat water passing through the unit on it's way to your faucet.

Humidifiers help to stabilize the humidity level in your home, which in turn improves the overall air quality. In the winter, if the humidity level gets too low, you'll spend more money on heating because you won't feel warm enough when the thermostat is set at an average temperature. Low humidity can also cause dry skin, sinus issues, excessive static electricity, and can even cause hardwood floors to dry and separate at the seams. If the humidity level in your home is too high in the summer then you won't be able to cool off, and you'll find yourself running the air conditioning more. If you set your humidifier properly then you will actually be able to save money on your heating and cooling bills.

Air Handlers
The air handler is used to actually circulate the cool or warm air throughout the duct work in your home. HVAC systems are only as efficient as the air handlers that push air throughout your home. An air handler is usually a large metal box containing a fan or blower, heating and/or cooling elements, filters, and dampers (if you have a multiple zone HVAC system). That's why matching your air handler with your system's size and capacity is crucial to sustaining the steady flow of comfortable air your home needs.

Air Filtration
Air filtration is an important factor of our indoor air quality. Your HVAC system's air filters clean the air passing through the system by removing particles, contaminants, vapors and gases from the air. The filtered air is then used in heating, ventilation and air conditioning.

UV Air Purifiers
An air purifier takes cleaning of the air you breathe to the next level. The purifier works to capture and kill dangerous bacteria, viruses and mold, safeguarding the air quality of your entire home. Indoor air is re-purified, not just filtered, as often as 8 times each hour.
