The focus at Varitek, Inc. for complete customer satisfaction on every job means we believe in offering products that we know will give our customers the performance and reliability we would require for our own homes. See below for information about the different HVAC products we carry.

Air Conditioner
HVAC systems typically have an indoor and outdoor unit that work together which is called a split system. An air conditioner is an outdoor unit, and it sends cooled air to the indoor unit for circulation through your home.
When properly matched with the indoor unit, you get maximum efficiency and longer system life. Air conditioning and cooling efficiency is measured using a Seasonal Energy Efficiency Ratio (SEER). A higher SEER means higher energy efficiency.

Heat Pump
A heat pump is an electric unit that is able to both heat and cool your home. As with air conditioning, heat pumps work in a split system design (instead of an air conditioning unit) to keep your home comfortable all year long. For climates where winter temperatures stay around 40 degrees, a heat pump is typically more efficient than a gas furnace. Heat pumps can also be used in hybrid system installations for maximum efficiency. Heat pumps efficiency levels are measured in Seasonal Energy Efficiency Rating (SEER) for cooling and Heating Seasonal Performance Factor (HSPF) for heating.

Furnace
A furnace is the indoor unit of a split system setup. Furnaces come typically as gas, electric or oil powered and provide warm air in the winter. Furnace heating ability is measured with an Annual Fuel Utilization Efficiency (AFUE) percentage. Remember, a higher AFUE percentage indicates a more efficient furnace.

Packaged System
In a packaged system, all equipment is built into an outdoor unit and often located on the room. The "package" that gives it its name provides central air conditioning during the summer and heat in colder months.
The primary advantage of a packaged system is that they are ideal for homes with space constraints that do not allow for a traditional split system. The efficiency of packaged systems is rated using SEER (for cooling efficiency), AFUE (for gas heating efficiency) and HSPF (for heat pump efficiency). Ductwork is required to transfer the heated or cooled air throughout the home.

Air Cleaner
Air cleaners offer an effective way to remove tiny particles - dust, pollens, pet dander, mold spores, fungi, bacteria, tobacco smoke, etc. - from the air that passes through the home. An air cleaner is given a MERV rating to rate the effectiveness of the unit. MERV ratings go from 1-16 with 16 as the highest rating possible.

Whole Home Humidifier
Fan Powered Humidifiers are independent units that add moisture directly into your ductwork with their own fans while a Bypass Humidifier works with your furnace to deliver moisture throughout your home. A whole home humidifier saves energy in dry winter months because a house feels warmer with the right humidity level. Proper humidity also helps protect wooden furniture and flooring.

Ventilator
Ventilators are part of indoor air quality solutions and replace a portion of stale indoor air with fresh outdoor air, reducing energy loss in the process. Air exchangers for instance, let users manually or automatically adjust the fresh air flow. The units retain energy used to heat or cool, saving money on utility bills.

Thermostats & Controls
Thermostats are the control system for your heating and air conditioning equipment. Thermostats will provide information on what the equipment is doing, when it needs to be serviced, and allow you to set the exact temperature and humidity you want to maintain in your home.
Programmable thermostats allow you to specify comfort control levels for the entire week while remote access controls allow you to adjust your HVAC system remotely via a telephone.

Boiler
A boiler is the heat source for radiant heating systems. Top of the line boilers are state of the art using cast aluminum heat exchangers as opposed to cast iron resulting in AFUE ratings up to 90% which means better efficiency resulting in lower utility bills.

Evaporator Coil
The coil is an important part of any quality home heating or cooling system. It’s job, heat transfer, is one of the most important factors in achieving heating and cooling efficiencies that keep your home comfortable all year long. An evaporator coil is a series of piping connected to a furnace or air handler that blows indoor air across it, causing the coil to absorb heat from the air. The cooled air is then delivered to the house through ducting. The refrigerant then flows back to the compressor (a compressor controls the pressure applied to the refrigerant) where the cycle starts over again.
