How Air Handlers Actually “Handle” Air in Your AC System

What do air handlers do for your air conditioning system? It, quite simply, handles the air. What does this entail? Most air conditioning units, especially in Silicon Valley, are “split” units. This means that they have units both outdoors and indoors. The air handler covers the indoor section of the air conditioning system which is extremely vital.

The role of the handler is to distribute the air through the entire house. The handler unit for indoor air is made of an air coil, blower and filter. The handler brings air in, flows it through the coils (to heat or cool) and then expels it back into the house with the duct system. It is the portion of the AC system that makes sure the air that gets treated flows throughout the entire home.

Air Handler Parts

  • Blower The fan blower will “blow” the rest of the cooled air back throughout the home by using the duct ventilation system.
  • Air filter This filter is placed between the fan and the intake vent to make sure that the air brought into the unit is filtered before it gets cooled.
  • Coils The coils are what truly cool the air inside the house. This occurs when the housed refrigerant within the external unit is drawn out as a high-pressure and high-temperature gas into the internal air handler. A valve then transforms this gas refrigerant into a low-pressure and low-temperature gas that’s brought to the coils. These coils then make the air cooler that’s getting passed over the coils and into the system of ducts. This “used” refrigerant is brought back outside to the external system to start the cycle once again. In the majority of homes in Silicon Valley, the coils can get hotter as well to provide the “heating” portion of a home’s HVAC system.

Would it be helpful for you to use an air handler?

When you use a split-system heat pump or air conditioner, then yes, you would want to use an air handler. The air handler will make sure the air involved in the cooling or heating process is circulating. It’s the indoor component that handles air in conjunction with the outdoor part.

The evaporator coil will bring the heat out from the building to then blow the cooled air through a set of ducts in the building that are connected with the air handler. Call O.C.

Are there different types of HVAC units?

HVAC manufacturers have engineered several different kinds of HVAC systems that people can choose from depending on their local weather conditions and preferences. There are climates in the U.S. range from the subarctic climate in Alaska to the hot, arid conditions in the desert southwest. There are humid climates in between as well as those that are dry, from warm to cold.

The main kinds of HVAC systems include:

• Air conditioners.
• Heat pumps.
• Gas furnaces.
• Radiant heating systems.

Air Conditioners

All central air conditioners require ductwork to distribute cooled air. They include two copper coils, one that contains the chilled refrigerant and the other that removes the heat from your home that the refrigerant absorbs, called the condensing coil. They use one fan to circulate the air the evaporator coil cools and another to blow off the heat in the condensing coil that the evaporator coil absorbs.

Most air conditioners have two separate components. The indoor air handler contains the blower fan and the evaporator coil. An outdoor condenser contains the condensing coil and the compressor, which alters the refrigerant pressure and circulates it through the system.

Heat Pumps

A heat pump is nothing more than an air conditioning system that contains a reversing valve. The valve switches the flow of heat from summer to winter. During hot weather, the refrigerant absorbs the heat from the evaporator coil and sends it outside to the condensing coil. In the cold months, the process reverses. The condensing coil absorbs the heat from the outdoor air and brings it inside.

Heat pumps work well in just about every climate except Alaska and the northern tier states. They’re the most energy efficient of all HVAC systems since they can extract or supply at least three times more heat or cooling energy than they use.

Furnaces

Forced-air furnaces use natural gas, propane, or oil as fuels. They are the most common kind of heating system in the U.S. Like air conditioners and heat pumps, they blow heated air through the ductwork to warm the home. They’re inexpensive, easy to install, safe and relatively durable.

Radiant Systems

Radiant heating systems are the oldest ways of heating homes. They use a boiler to heat liquids that circulate through tubing placed in walls, floors or ceilings. They provide comfortable, long-lasting heat for homes in cold climates. They’re especially good for people with airborne allergies since they do not blow air.

Is Residential Air Conditioning Repair Different from Commercial Repair

Residential and commercial air conditioning repair services are different in a variety of ways. It takes a company that specializes in commercial air conditioning services to handle large projects. Many residential projects involve only one unit that will cool off an entire home with ease. When it comes to commercial projects, there are often multiple units, temperature zoning, and more to address.

Things to think about when it comes to commercial air conditioning repair:

  • The size of the units must be big enough to cool off a room with many employees
  • Different zones should be set up for optimal comfort
  • It is important for everything to be done by experienced commercial technicians

Commercial Air Conditioning Must Be Done Right

When it comes to commercial air conditioning, skillful technicians must figure out how large your units should be and also how many units it will take to cool off your property. There will be many people involved in a commercial project like employees, students, or customers, so it is important to have a unit that will keep them all cool enough.

Of course, there is no need to get units that are too large or to have more units than needed because this will just use more power than necessary. A company that specializes in commercial air conditioning services will be able to make your life easy by helping you design the best system for your unique needs. Air conditioning specialists can set up different zoning areas throughout your entire building.

This will allow you to be able to change the temperature in different rooms with ease. You can personalize different spaces to make sure that everything stays at the right temperature.

What Are the Benefits of a Silicone Heater?

Silicone heaters are heating instruments that are most commonly used in residential and commercial projects that require smaller spaces to have direct contact with an industrial heater. Many of these spaces would be difficult to reach with mainstream heaters, but the flexibility of the silicone used to manufacture these units makes them much easier to maneuver.

Silicone heaters are constructed with either etched foil or wiring systems that can rapidly heat up to 350° Celsius, giving them adequate power to quickly heat up surfaces they come into contact with.

Resistance to Chemicals and Moisture

Silicone is considered an elastomer, and it is known to be highly resistant to many dangerous chemicals, as well as the harmful effects that moisture can have on traditional heating systems. This is due to silicone being made of durable polymers that are specifically built to have ultra resistant structures for high levels of protection. With silicone being impervious to chemicals and moisture, it is the perfect material for an effective transportable heating unit.

Temperatures Elevate at Exceptionally High Speeds

The thin construction associated with flexible silicone heaters allows the material to heat up incredibly quickly. Both etched foils and etched wires end up creating the perfect environment for a speedy conduction process. This aids in the efficiency of silicone rubber heaters, allowing them to complete projects that they are used for in record time. Since silicone is inherently heat-resistant, quickly reaching these high temperatures should pose no risk for the heating unit itself.

Easily Transported from Place to Place

On average, silicone weighs a little over 2.5 grams per cubic centimeter. This lightweight feel allows silicone heaters to be transported in a user-friendly manner. Larger heating units such as drum heaters are often big enough to hold over 50 gallons, making them quite a hassle to transfer from one work space to the next. Silicone heaters are not just lightweight, but they are also known for their flexibility which makes them much easier to store for future use.

If you find yourself in a position where a durable heater is needed for hard-to-reach spaces, a silicone rubber heater has the perfect specifications to get the job done. It is no longer necessary to haul around heavy heating units that may be too bulky to get the job done with the availability of silicone heating technology. Investing in silicone rubber heaters will give you the satisfaction of a high-performance result in a sensible amount of time. Call us today at 408-295-2182.

What are the costs to have an HVAC compressor repaired?

No matter what type of air conditioning system you have, it will eventually fail and need repair. The average A/C system has four primary parts: Compressor, condenser, expansion valve, and an evaporator. The compressor is the engine that drives your A/C system. It compresses refrigerant(freon) and circulates it throughout your system to keep your home cool. If your compressor is not functioning properly, your A/C will perform poorly or not at all.

So how does a compressor work? A compressor pushes hot gas into your outdoor condenser unit. This unit has a large fan that blows air on the condenser coils to cool the hot gas and also transfer any remaining heat into the outside air. This process provides cool air to move throughout your home. This is a complicated process that requires all major components working at an optimal level to achieve the desired results and efficiency.

Cost to Repair

The cost to repair an HVAC compressor will vary greatly depending on such factors as the type system, geographic location, and the company that performs the work. Although you may be tempted to repair the compressor yourself to save money, it is best to have it repaired by a professional because it is a complicated and potentially dangerous process. You can expect to pay between $1,000 and $2,000 to have your HVAC compressor replaced.

Some typical causes of HVAC compressor failure are listed below:

  • Failure to properly maintain the system
  • Overcurrent or overvoltage conditions
  • Excessive moisture conditions that can lead to corrosion or other negative chemical reactions

Additionally, it is important to keep your air filter replaced regularly to reduce the load on your compressor and system. If you notice your outside condenser pad starting to sink, this should be immediately corrected to prevent strain on the lines and wiring which could lead to short circuits. Also, if the pad sinks too low, the compressor could become submerged in water during heavy rainstorms. If you notice your system or compressor are noisier than normal, it should be promptly inspected by a professional. This could possibly save you thousands by correcting minor problems before they become major problems.

If your A/C system requires maintenance or repair, call us today at 408-295-2182.
