Schedule an EverRest dealer visit Factors affecting the size of your new system include the climate in your region, humidity levels, the number of windows in your dwelling, total square footage of your home, the direction your home faces, the number of heat-producing appliances in your home, the type of insulation you have and the number of people that live in your residence.
An EverRest dealer can perform the proper calculations to determine the appropriate heating or cooling unit for your home and lifestyle. Putting a new system in a home that has not had central air and heat before will require the installation of ductwork, insulation, refrigerant piping, electrical service, wiring, thermostat, condensate piping, flue piping, flue terminations, chimney liner, slabs, filter, driers, registers, grills, drain pans and evaporator coil.
Beyond equipment, the most important component installed with a new system, however, is the ductwork. Ductwork is composed of two parts, supply and return. Supply duct is attached to the outflow of the new system, delivering air to each zone in a home.
The amount of air reaching each zone is determined by the size of supply ductwork connecting it to your system. Your dealer will help you determine the size of all the supply ductwork in your home. The second part of the ductwork, the return duct, attaches to the inlet of the new system and draws air out of the spaces to be heated or cooled.
Attached to the return duct is the filter. The filter should be placed as near to the furnace or air handler as possible. Ductwork can be either fiberglass or metal and must be properly sized in order to evenly distribute the proper amount of air to each room.
Start with a detailed inspection To install the most efficient HVAC system in your household, a detailed inspection should first be performed by your installation contractor. Proper maintenance is key Maintenance and service play a key role in the lifecycle of a heating or air conditioning system. If all recommended maintenance and service actions are taken, an air conditioner can last 12 to 15 years and a gas furnace 20 to 25 years.
It is generally a good idea to replace the indoor coil if you are also replacing your air conditioner or heat pump. There is a correlation between the efficiency of your heating or cooling system and the performance of the indoor coil and changing out the current indoor coil for a new one may be critical to optimizing the performance, the efficiency and the savings potential of your new system.
Technicians may have work opportunities in sites like homes, offices, government agencies, schools, hospitals and construction work sites. They may have to work in tight spaces like ventilation ducts as part of these HVAC jobs. HVAC certification programs are offered primarily by community colleges and online schools while apprenticeships may be offered at industry-specific businesses.
Program length varies by school but the typical length is six months to one year. Coursework in these programs may cover HVAC system design and specifications, duct work and piping systems, building codes, energy management and facilities management. These programs work to prepares students for licensing and to start working upon completion of the courses. Once an HVAC certification program is completed, the next step is usually getting a state license if the state requires one for employment.
Each state has different licensing requirements for an HVAC license. While these are the most common life spans, many homeowners choose to replace their HVAC system sooner. As the system ages, it will gradually become less reliable and efficient, increasing repair and utility costs.
Once a system is 10 to 15 years old, the monthly energy savings from upgrading to a newer, more efficient model can often justify the initial investment, especially if the current system is unreliable or has major problems.
Of these, poor maintenance and oversizing are the most detrimental. A lack of maintenance can lead to accelerated component wear and a dramatically shorter life span, while oversizing can cause frequent on-and-off cycling, leading to compressor or blower motor failure. Additionally, air conditioners or heat pumps in coastal areas will also see significantly reduced life spans due to salt corroding the condenser unit.
With preventive maintenance plans, HVAC systems will last longer because small issues are caught before they require costly fixes.
