HVAC Systems (Heating Ventilation Air Conditioning)

HVAC is a combination of systems that keep your home cozy at any given time of the year.

With an HVAC system, you have the indoor air cleaned by removing dust, pollen, smoke, and impurities. It does this by maintaining the condition of the indoor environment through cooling, heating, ventilating, humidifying, dehumidifying, and controlling air movement.

With an Uxbridge HVAC company such as Marx Mechanical Contracting, you will have comfortable temperatures, and the best air quality, year round.

To get the best and most out of your HVAC system, it’s vital that you understand how all of the HVAC components work.

Recognizing HVAC in Uxbridge

Have you seen the big air conditioner boxes visible on top of some offices or apartment buildings? Those are examples of HVAC systems. You find these mostly in large buildings, apartment complexes, industrial buildings, skyscrapers, and extensive interior environments…

But also, the cooling and heating systems you use at home are HVAC systems, they take a different form altogether, but they operate on the same fundamental principles.

The efficiency of operation is more or less the same.

Types of HVAC systems

Did you know that heating and cooling accounts for over half of the energy used in many homes across Uxbridge? Therefore, when choosing an HVAC system, you have to select one that will meet your comfort needs without consuming excess power and escalating your living cost.

Heating systems:

Heating systems are in different forms. Some are boilers that heat water for steam radiators; others are forced water systems with baseboard radiators, heat pumps, boilers and electric heat. Some are furnaces where heated air is pushed through duct work. The furnace generally operates on propane or natural gas, while a boiler uses oil or gas to heat the water.

A radiator floor, otherwise known as a hydronic heating system, is another perfect option. The system uses piping underfloor, and it’s made up of flexible tubes filled with glycol solution or water. These can heat concrete and any floor, and it’s an efficient method of maintaining warmth in your home. For wooden flooring, the system will require careful installation in sheathing.

Cooling systems:

You get air conditioners in many forms, from the portable window-mounted box that can be pulled out when needed to the massive boxes designed to cool an entire home. You can install air conditioners on your own, but the problem is when you get stuck in the process, something that’s pretty common. Installation is a significant project and the exterior and interior elements of the system but perfectly interconnected for optimal performance. A popular choice for drier climates is the evaporation cooler. It draws outside air into the cooling system, which passes through saturated pads, thus cooled and moistened before it’s pushed to the living space and displaces the hot air.


An HVAC system maintains the quality of your home’s indoor air. Ventilation ensures proper air circulation, purification, moisture control, repugnant smell removal, and stagnation of air.

Ventilation can be done mechanically through an HVAC system, naturally by having enough fans and windows or even a combination of the two.

  • A forced-air system pushes air in your home through an air filter which keeps volatile organic compounds, airborne particulates, and allergens off your home. When you’ve no fixed cleaning system, you have to use tools like air purifiers, cleaners, humidifiers, and dehumidifiers.
  • You must understand how your home HVAC system keeps your home ventilated. That’s to ensure you address any breathing or allergy issues that your family may be encountering.
  • One of the things many homeowners are not aware of is that HVAC system circulates and purifies the air by continually supplying excellent and clean air for the indoor environment. Thus, the harmful particles are removed, and your home smells good.

Moisture accumulates every time in your home due to some activities like bathing, cleaning, and cooking. And too much moisture leads to the growth of molds, mildew which damages your walls, floor, and other structures in your home. In severe cases, the mold leads to health problems. HVAC system controls your indoor moisture levels.

Understanding the Air Conditioning Flow

Apart from heating, your HVAC system is responsible for the cooling of your home. Though there are several air conditioning units, the functioning is pretty the same. As the AC system collects and expels warm air, the refrigerant constantly changes it from gas to liquid. The moist air passes through the compressor and turns into hot vapour, and moves to the condenser.

Then the hot liquid is cooled and then passed to the evaporator coil. After the mist evaporates, heat from the inside is absorbed and returned to the compressor, and the process starts all over again.

Heat Recovery Ventilator

A heat recovery ventilator is like a balanced ventilation system ideal for homes located in colder climates. The heating system allows you to get rid of the excess moisture during the heating season. It supplies continuous fresh air from outside, and the recovery core transfers a portion of the heat to the air coming from outside before it’s distributed throughout the house. Thus, you have a continuous supply of fresh air and consequently increased comfort in your home.

The typical HRV system features two fans; one that takes out household air and another that brings in fresh air. The heat exchange core is what makes HRV unique. When cooling the engine, it behaves like your car radiator, transferring heat from the outgoing stream to the incoming one. This happens through some narrow alternating passages where incoming and outgoing air streams flow.

HRVs are ideal for replacing humid air in moisture-prone and tight homes with fresh and dry one. In climates that have excess humidity, an energy recovery ventilator is more suited.

Though HVAC system is one of the crucial systems in your home, it’s a pretty complicated one.

Thus, it’s one of the least understood systems in your home, but a basic understanding of it helps you in essential maintenance, so you don’t have to suffer the cost of repairs if it goes faulty. Again, you’ve to ensure regular maintenance by a reputable professional contractor. That way, you enhance the efficiency and lifespan of the HVAC system.
