The majority of us consider heating and cooling standards. We rely on air conditioning to maintain cool throughout the summer and on our furnaces to stay toasty during the winter.
The natural response is to contact for expert help when the residence is chilly in the winter or sweltering in the summer. Thankfully, there is another option. By performing basic maintenance and simple repairs yourself, you may significantly save service expenses and keep home air conditioning and heating systems operating at peak performance.
But first, it is crucial to understand the fundamentals of how air conditioners and heaters work.
Air Conditioning & Gas Heating: Which Is For You?
A source of heated or cooled air, a way to distribute the air throughout the rooms getting heated or cooled, plus a control tool to govern the system (such as a thermostat) are the three essential parts of every climate control device or system.
The distribution and management systems for the sources for warm air, like a furnace, plus cool air, like a cooling device, in a home are frequently the same. If your home has air conditioning that is centrally the same ductwork and thermostat likely control the flow of heat and cold air.
Any one of these three fundamental parts might be the source of an air conditioning or heating system’s dysfunction. Heat always transfers from a heated item to a colder one, similarly to how water flows between a higher toward a lower level, which is the basis for how both air conditioning and heat function.
Air conditioners take heat from the air to cool down your home; furnaces and heaters add heat to the air to warm up your home. Your local air conditioning technician should be able to troubleshoot and repair your system, regardless of the type of system you run in your home.
Fuel is used by all systems for cooling and heating. Electricity is used by air conditioners. While some systems utilize electricity, the majority of residential warmth systems use gasoline or fuel oil. Air is heated and cooled by the heat pump, an electrically driven temperature control device.
It draws heat through the air within your house in the summer. It uses the heat it extracts from the outside air during the winter to warm its surroundings inside.
Whether it is gas, oil, or electricity, the fuel that drives the furnace is used when it is switched on. Heat is generated as fuel is consumed, transported to your home’s living spaces via ducts, pipes, or wires, and then expelled through registers, heating elements, or heating panels.
Older systems heat water using the heat they generate, which then heats the atmosphere in your home. In these systems, the water supply is heated and stored in a boiler before being pumped as hot water via pipes that are buried in the floor, walls, or ceiling.
An electrically driven fan called a blower drives air through a network of metal ducts and into the rooms of your home to disperse the heat or coolness generated by the furnace or central air conditioner.
The colder air entering the rooms is returned to the furnace through a different system of ducts known as the cold air returning system as the warm air that extends from the furnace enters the rooms. You may change the system’s settings to alter how much air moves through your house.
The same forced-air framework, including the blower, is used by air conditioning units to circulate cool air throughout the rooms and return warmer air to be cooled. Blower faults are the most common cause of forced-air system issues.
Additionally, the blower may be loud and raise the price of furnace fuel by using more electricity. However, a forced-air system works well to distribute heated or cooled air throughout a house since it uses a blower.

Your HVAC technician should be able to fully repair either of these systems should you need any repair work performed. Although they sound as though they might be complicated systems, your local HVAC company should be able to troubleshoot your system and perform any necessary repairs to get your system back online.
Radiant Systems
Radiant systems work by warming a room’s walls, floors, or ceiling, or, more frequently, by warming the radiators inside the space. The atmosphere in the place is then warmed by these items.
The idea behind gravity systems is that hot air rises and cold air lowers. Therefore, it is impossible to transfer cold air from a cooling device using gravity systems. The furnace is situated close to or below the floor in a gravity system. Through ductwork, the heated air rises and is distributed throughout the home through registers in the floor.
Heat registers are often installed high up on the walls if the furnace is on the main level of the home since they must always be lower than the furnace. Click here to read more on heat registers. Warm air rises in the direction of the ceiling. As it cools, the air sinks, travels through the ventilation ducts, and then returns to the furnace where it will be warmed.
The radiant system is yet another fundamental heating distribution method. Hot water heated by the combustion process and circulated via pipes buried in the plaster of the wall, floor, and ceiling serves as the typical heat source.
Some methods produce heat that is transmitted into rooms using electric heating panels. These panels, like gravitational wall heaters, are typically installed in warm climes or in areas with reasonably priced power. Cool air through an air conditioner cannot be distributed via radiant systems.
Hot water heating systems employ convectors and radiators, the most popular radiant heat distribution methods in older dwellings. To move warm water from the water heater to the heaters or convectors, these systems may rely on gravity or a circulator pump (https://www.commerce.wa.gov.au/sites/default/files/atoms/files/195697_web_rules_for_pools_and_spas_a4_booklet_feb_2019.pdf). A hydronic system is one that utilizes a pump or circulator.
Modern homes with slab foundations frequently have radiant heating systems installed.
Under the concrete slab’s surface is a network of interconnected hot water pipes. The air that touches the floor surface heats up as the pipes warm the concrete. The air all through the entire home will ultimately be heated by the slab, so it does not have to be very hot.
