What is HVAC? And How Can I Benefit from a Specialist?

The central climate control of your home is sometimes called your Heating Ventilation and Air Conditioning system or HVAC for short. You may also have heard the terms central heat, central air, or any number of less modern variations. The trade of HVAC comprehensively encompasses baseboard heating to stoker stoves and everything in between. When you are having problems with your HVAC, you need to find professionals or research the web for professional tips. Failure to act promptly when you are experiencing operational problems can lead to major headaches down the line.

What is the Difference Between an HVAC Specialist and a Plumber?

Professionals who specialize in HVAC repairs do not replace or repair your plumbing, in the general sense, but may work with your hot water pipes in a limited degree when they interface with a furnace or heater. The majority of jobs available for an HVAC specialist are related to cleaning or repairing the ductwork, replacing or repairing a heat pump, and energy usage analyses. They are often in charge of maintaining large commercial systems with intricate parts, wiring, and piping. They are experts in refrigeration and required to meet certification tests and receive extensive training in the field.

Plumbers often make their living off installing bathtubs, showers, toilets, sinks, and repairing pipes throughout the home. When you need a hot water heater installed, it is plumbers and not HVAC specialists that are needed. Plumbers work mostly with torches and solder to install copper tubing. However, many are now receiving special training to work with other plastic flexible tubing materials that do not corrode like cast iron or develop pinhole leaks in the solder joints like copper.

Why Are Home Energy Audits Important?

When your HVAC specialist does an energy audit, they check to see how efficiently your heating and air conditioning systems are operating. They may need to make repairs or adjustments to maximize the efficiency of your system.

Why Do I Need an HVAC Specialist to Service My Central Air Annually?

Refrigeration is a complex field because there are certain reactions that have to be perfectly timed and coordinated to produce efficient refrigeration. A key to a refrigeration system is the type of gas that it contains. There are only certain types of gases like methane, R-134a, and other Freon isotopes that will perform effectively in a refrigeration unit.

As component of air conditioning service,  the gas has to turn into a liquid and then back into a gas again. During this process, it will transfer heat by absorbing it in the evaporator and releasing it in the condenser when it cools off. The compressor unit of an A/C system pressurizes the gas and circulates it through the system.

In addition, the gas has to significantly drop in temperature when it expands into its gaseous form. This is the real magic that allows air conditioning to happen. Because simply circulating water by this same heat exchange method would not be very effective at refrigerating items down into the very low temperature ranges. This is pure magic that is only possible as a gift from Mother Nature to mankind.

The receiver dryer acts to filter the refrigerant and to remove any moisture that may be absorbed through micropores in the system.As check during heating repair one fatal flaw in many aging air conditioning systems is the seals. Because the rubber deteriorates and breaks down quicker than any other part of the machines, the seals often go bad and need to be overhauled after so many years. If the system is not checked annually for leaks and serviced, it can burn out the compressor and corrode the internal systems.
