Having an HVAC system is essential for keeping your home comfortable and safe. Understanding how it works can help you troubleshoot problems when they arise.
Rolling up your sleeves to do DIY maintenance is fine for some projects, but you should always leave HVAC installation and repairs to the experts. Haphazard repairs may damage the system and void the warranty.
The evaporator coil, which is located within your air conditioning system’s indoor unit, is one of the most important components to your cooling system. It plays a central role in the cooling process, and it works hand in hand with the condenser coil to absorb heat from indoor air.
The coil is comprised of a network of copper tubes that are designed to facilitate the transfer of heat. When warm indoor air passes over the coil, it transfers its heat to the refrigerant, causing the liquid to evaporate into a gaseous state. The resulting cooled air is then circulated throughout your home’s ductwork to provide refreshing comfort.
While you can do simple cleans to your evaporator coil, if you suspect that it’s having trouble or needs to be replaced, call an HVAC professional. This is a job that requires special training and equipment as it involves working with potentially dangerous chemicals, including refrigerant. An HVAC professional will also be able to spot signs that a problem is coming and recommend the best course of action for your situation.
Thermostats are a vital component of any HVAC system. They are used to regulate the temperature of a room by switching on and off heaters as needed. They are usually wall or boiler-mounted and control a heating device directly or indirectly (such as electric baseboard heaters, oil furnaces and some boiler zone valves). The old thermostats with the dials are a thing of the past; today’s models are digital with easy to read displays. Some even have a programmable interface and offer 30% energy savings when left on their default programs.
These digital devices use a small electronic sensor called a thermistor to sense temperature. It uses a change in resistance to calculate a measurement and then sends this information to the central system. They can also come with a built-in time delay function to prevent overheating and wear and tear. They’re a good choice for homeowners that want to avoid unnecessary heating and cooling costs.
The fan motor is a vital part of your HVAC system. It facilitates the dissipation of heat, which is critical to your air conditioner’s operation. If this component isn’t functioning correctly, it can affect the efficiency of your whole system.
Some common signs that a fan motor is on its last legs include a rattling noise and a buzzing sound. If you notice a burning smell, this could be a sign that the motor is overheating.
If you suspect that your fan motor isn’t working properly, shut off the power to it at the circuit breaker or fuse box. Next, use a multimeter to test the motor’s windings for continuity. If the resistance is high, you’ll need to replace the motor. Make sure to consult a technician to ensure that you select the correct type of replacement. You can find a wide variety of AC fan motors in various classes. For example, there are ODP (open drip proof) motors and TEAO (Totally Enclosed Fan-Assembly Oil) motors.
The ductwork of an HVAC system is the network that moves clean air throughout your home. The main purpose of ductwork is to transfer heated or cooled air from the furnace or AC to different rooms.
Ducts can be made from a variety of materials. Some are more durable than others. They may also come in different shapes.
Metal ducts, such as galvanized steel or aluminum are the most durable and least likely to harbor mold. They are rust-proof and easy to install.
Fiberboard ducts have a sealed interior to limit heat loss, but their textured exteriors can trap dirt and make them difficult to clean. They are also prone to mildew and mold growth in humid climates.
Flex ducts consist of a steel spring coil wrapped in a helix and covered in 2-ply polymer plastic, which is flexible and easier to install. They are less expensive than rigid ductwork and work wonders in hard-to-reach spaces.Hvac parts near me
