You may wish to consider replacing your heat pump or air conditioner if it is old, inefficient or in need of repair. Today's systems are as much as 60% more efficient than those systems manufactured as little as ten years ago. If you are concerned about utility bills or are faced with an expensive repair, you may want to consider replacing your system rather than enduring another costly season or paying to replace an expensive component. If you plan on financing the purchase, the monthly savings on your utility bill should be considered when determining the actual monthly cost of replacing a system.
Many factors affect the cost of an air conditioner and heat pump system, including the size of your home, the type and condition of the ductwork installed and accessories you might need such as a thermostat or an electronic air cleaner. Your local dealer can assist you in finding the right system to meet your needs.
Confirm with your your retailer that the capacity of the new air conditioning and heating system will meet your real needs. Your dealer will provide a load calculation for your home. Also ask the dealer to provide an energy analysis to determine operating cost. Some products can reduce air stratification and uneven temperatures from room to room. If you have allergies, an indoor unit with an ECM motor will allow you to circulate the air in your home continuously while filtering the air for about the same cost as operating a standard light bulb. Finally, know your budget parameters and the efficiency of the system being proposed. Does the system offer a payback? In other words, will the monthly savings over time offset the cost of the new unit or efficiency option being considered?
Aside from the placement of the new air conditioning or heating equipment, your dealer will inspect several items and determine whether or not these items need to be supplied or replaced. Some of the items include: 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.
If an air conditioning and heating central system is being added to the home for the first time, most of the items noted in the previous question and answer may be required to install the new system. Besides the equipment, the most significant component is ductwork. The ductwork needs to be properly sized to deliver the right amount of air to each room. The ductwork consists of supply and return ductwork. Your dealer will determine the size of the ductwork going into a space by the amount of air that needs to be delivered to the space.
With the proper attention, heating and air conditioning systems can keep you comfortable year-round. Heat pumps and oil-fired furnaces and boilers need a yearly professional tune-up. Gas-fired equipment, on the other hand, burns cleaner and can be serviced every other year. A close inspection will uncover leaks, soot, rust, rot, corroded electrical contacts and frayed wires. The inspection should also cover the chimney, ductwork or pipes, dampers or valves, blower or pump, registers, the fuel line and the gas meter or oil tank — as well as every part of the furnace itself.
Next, the system should be run through a full heating cycle to ensure that it has plenty of combustion air and chimney draft. Finally, cleaning the burner and heat exchanger to remove soot and other gunk will prevent such buildup from impeding smooth operation. A check of the heat pump should include an inspection of the compressor, fan, indoor and outdoor coils and refrigerant lines. Indoor and outdoor coils should be cleaned, and the refrigerant pressure should be checked.
Tuning up the distribution side of a forced-air system starts with the blower. The axle should be lubricated, blades cleaned and lower motor checked to insure the unit isn't being overloaded. The fan belt should be adjusted so it deflects no more than an inch when pressed.
While thermostats rarely fail outright, they can degrade over time as mechanical parts stick or lose their calibration. A technician can recalibrate the thermostat but electronic thermostats cannot be recalibrated.
A neglected in-duct humidifier can breed mildew and bacteria, not to mention add too much moisture to a house. A common mistake with humidifiers is leaving them on after the heating season ends. Don't forget to pull the plug, shut the water valve and drain the unit. A unit with a water reservoir should be drained and cleaned with white vinegar, a mix of one part chlorine bleach to eight parts water or muriatic acid. Mist-type humidifiers also require regular cleaning to remove mineral deposits.
Most houses with forced-air furnaces have a standard furnace filter made from loosely woven spun-glass fibers designed to keep it and its ductwork clean. They need to be changed monthly (1’’ filter) and for the 4’’ to 6’’ filter every 2 season.
A maze of heating and air conditioning ducts runs inside the walls and floors of most homes. As the supply ducts blow air into the rooms, return ducts inhale airborne dust and suck it back into the blower. Add moisture to this mixture and you've got a breeding ground for allergy-inducing molds, mites and bacteria. Many filters commonly used today can't keep dust and debris from streaming into the air. To find out if your ducts need cleaning, pull off some supply and return registers and take a look. If a new furnace is being installed, you should probably invest in a duct cleaning at the same time, because chances are the new blower will be more powerful than the old one and will stir up a lot of dust.
Seasonal Energy Efficiency Ratio; a measure of cooling efficiency for air conditioners and heat pumps. The higher the SEER, the more energy efficient the unit. Energy efficiency equates to lower electrical bills. Currently minimum SEER rating is 13.
A ductless mini-split air conditioning and/or heating system is comprised of an indoor unit called the evaporator and an outdoor unit called the condensing unit. The evaporator is connected to the condensing unit by copper tubing and electrical wiring which is passed through a 2 ½” – 3” hole. Basically, it is a small central air unit with the flexibility of cooling or heating one room or more; zoning.
You must install cover-up at the time of installation.
It is not recommended to paint the evaporator. If for any reason a problem occurs with the unit in the future, the warranty will become null and void.
No, the warranty will become null and void
The plasma filter has a life span of 6 to 8 years and should be washed every 400 hours of use. The filter easily detaches to be washed with mild detergent. The filter is not dishwasher safe. A LED light on the indoor evaporator unit will notify you when it is time to clean the filter. If the light is ignored, the unit will automatically shut down after 100 additional hours of use until the filter is washed.
Detailed instructions for maintenance can be found in each model’s Owner’s Manual.
An air exchanger does not produce humidity. It is used to evacuate excess humidity in the winter. The use of a humidifier may be required.
In this case, you must contact a ventilation specialist.
An independent ventilation system is required for a crawlspace, therefore different from the system used for your house.
Yes ventilation norms exist. It is important to find out from your municipality, which one applies. They have the responsibility to ensure the norms are applied.
Your home’s humidity level depends on outdoor conditions. The use of a dehumidifier orair conditioner may be required.
Many reasons: window quality, heating temperature, window obstructions (blinds, curtains, etc.), dominant winds, drastic outdoor temperature changes.
Yes. However, only the manufacturer’s warranty still applies. Beware of “in-house” warranties offered by contractors; you must always make sure it will be honoured by the manufacturer.
Check the drain of pump to see if they are clogged.
It depends on many factors i.e. construction type, year of construction, building orientation, etc. It is best to contact a specialist who will know what to recommend.
