How to Find the Air Filter for the HVAC System in Your Home I can’t find the air filter in the HVAC unit in the home we just bought. Do all central heating and cooling units have filters? All central heating and cooling systems should have an air filter, but the filter can be harder to locate on some HVAC units than others. The air filter is usually located in the return air duct or blower compartment before the return air reaches the air handler. This allows the filter to clean the air coming from your house before it enters the HVAC unit. Common locations for air filters in HVAC units include: On horizontal HVAC units with the return duct attached to the side of the air handler, the filter often fits in a slot on the return air (intake) side of the unit. On vertical air handlers with the return air duct entering on the top of the air handler, the filter often slides into a slot above the HVAC unit. On vertical air handlers with the return air duct entering below the air handler, the filter often fits in a slot located below the HVAC unit.

On other HVAC systems, the air filter may be located behind the return air grill on a wall in your home. On HVAC systems with a return in each room, there may be an air filter behind each of the return grills.

They can be configured horizontally or vertically to ensure they will fit wherever they are used. The air handler can easily be installed above ceilings or in crawl-spaces, closets, basements, or the attic. The modular layout of our air handler lets you choose the right options for your project. Modules can be combined as heating only, cooling only, or a heating and cooling fan coil unit.

Each air handler accommodates a blower module, which adjusts proper airflow and can be used as ventilation only. You can also select a standard refrigerant based heat pump (will heat and cool) coil, a refrigerant based cooling only coil, chilled water coil, hot water coil or electric based heating module.window ac units for casement windows The Unico air handler provides a variety of options to improve the outcome of your system, including a return air box, drip pan, humidifier, and air filter. add freon to ac costTo protect your home, we also offer high filtration and venting systems, for fresher, cleaner air, and UV light options to kill bacteria.hvac drain pan coating * (Recommended minimum # of Outlets - 6 per ton)Flexible duct is available already insulated.

A basement that is pleasantly cool in the summer can become unbearably cold in winter, frustrating your desire to turn it into new living or utility space. On the face of it, the answer is as simple: Run a heating duct from the attic to the basement. In reality, such a task can be complicated, calling for an evaluation of the heating system, the building structure and your remodeling skills. Crunch the Numbers When it comes to dealing with heating, ventilation and air conditioning, the first tool you should pick up is a pencil. Even when your goal is as clear as running a single heating duct, a bit of planning can save you time, money and a great deal of exasperation. Start by finding out the capacity of your HVAC unit, then use one of the many calculators available online to determine its current heating or cooling load. If you have the extra capacity, you can move on to the planning phase. If the unit is barely able to keep up with its current demands, adding another zone will only make matters worse.

You may need to upgrade or consider alternative methods of heating the basement. Get the Big Picture Draw a floor plan of your home, including the location of the HVAC air handling unit, the existing ducts sprouting from it and the room or rooms in your basement where you would like to place new registers. Pay particular attention to any major obstructions between the attic and basement. Moving a single pipe or electrical wire isn't bad. Dealing with the maze surrounding a bathroom or electrical service panel can be a lengthy, expensive nightmare. Pick Your Delivery System HVAC ducts come in many different sizes, shapes and materials. While sheet metal is arguably the most efficient from an air-flow standpoint, many homeowners and professionals prefer flexible ducting because it's lighter, faster and easier to install. You can also mix and match. For instance, use a flexible duct from the air handler through the attic to the point you've chosen to start downward, then switch to round or rectangular sheet metal from the attic to the basement.

Whatever you elect to use, make sure you install it correctly according to the manufacturer's specifications and follow any applicable building codes. Search for Hidden Space Unless you like the industrial look, the obvious problem when running ducting through an existing living space is where to put the duct. Wall cavities are frequently used, and are a good choice during a remodel. A retrofit is more involved but worth considering if you're a drywall ace and comfortable rearranging the structural members of your house. A less-invasive option is to look for spaces to hide the duct. Perhaps you could run it down one corner of a closet, or build a false wall that could be used as a built-in bookcase or additional storage as well as camouflage. By planning the route of a duct carefully, you can avoid costly and complicated obstructions while turning the potential eyesore of a mechanical necessity into an architectural flourish.
