This is one do-it-yourself project that could literally kill you if done incorrectly. Second, some brands have found that the return rate is higher on products purchased online — presumably because unqualified people have installed the product, and damaged the unit in the process.
Third, although the brands typically sell to regional distributors, their bread and butter depends on HVAC contractors recommending their brands to buyers. Thus, they tend to favor policies that keep their contractors happy. Finding a Qualified Contractor A number of consumers have reported finding that HVAC companies are reluctant to work with them when they have purchased equipment direct from an online distributor. In order of convenience, they are: If you have worked with an HVAC contractor previously, give them a call, explain what you want to do, and see if they are interested in working with you again.
Ask your friends and neighbors if they have an HVAC contractor that they recommend. Call this contractor, tell them that a friend or neighbor referred you, and see if they are willing to work with you. If you purchase your equipment from a big box store, they may offer an installation service. These contractors are typically independent companies that pay the big box store a marketing fee to provide them with homeowners looking for a contractor.
If you have oil or propane delivered to your house for your furnace, call the company, and see if they have an HVAC contractor on-staff. They may be willing to work with you, since you have an ongoing relationship with them.

There are three basic components — heating system, cooling system, and ventilation, to deliver efficient results. HVAC systems heat the environment with the help of a heat pump by absorbing heat from the outside, distributing it inside.
Or with the help of a furnace where heat is generated either through electricity or burning a fuel source which is then ventilated inside. In warm climates, the air conditioning system absorbs the heat within the environment and moves it to the outdoor unit, where the warm refrigerant gas is taken to the compressor to remove ambient heat and turn it into its liquid form.
This liquid refrigerant is then passed through a condenser and evaporator coil, which converts the liquid refrigerant into cool air that is passed through the vents and air ducts. Read in detail about how HVAC system works to cool your home. Below is a list of the components that contribute to an efficiently working HVAC system. This is the most interactive part of the entire HVAC system.
It controls the heating and cooling devices by switching them on or off or by regulating the airflow to maintain the desired temperature. Air conditioners distribute cool air throughout your home using a circuit or series of connected ducts. A refrigerant circulates between the condensing and evaporator coils, and the air is cooled as it passes through the evaporator coil.
A blower assembly — fan and motor — provides the necessary circulation to distribute the conditioned air. Central air conditioner installation is most common in warmer climate regions. A furnace is part of the forced air family.
There are various types of furnaces, with the most common using gas combustion or electric resistance heat strips to produce the necessary heat. Most furnace installations are equipped with a blower assembly to distribute the heated air throughout the home.
Since a furnace can only produce heat, it is sometimes retrofitted with a central air conditioner to provide cool air during the summer months. A heat pump is a variation of a central air conditioner. Heat pumps are capable of delivering both heated and cool air. They work by transferring the inside heat outside during the summer months to cool the home and extract heat from outside air or ground inside during the winter months.
Heat pump systems are one of the most energy-efficient systems available today. Although a system with a heat pump will cost you more upfront, the energy savings realized over the first few years of its operation usually pay for the additional costs. Air return is the starting point of your ventilation.
Its main purpose is to suck the air along with its pollutants and contaminants from the environment through filters to be cooled or heated. This also helps to maintain air quality and airflow. Exhaust outlets are used to remove heat and gas from the environment, and it can be done through chimney flue or vent stack. Ducts help to distribute heated and cooled airflow to maintain acceptable indoor quality of air. A compressor is part of the outside AC unit that helps to turn the warm refrigerant gas into liquid.
It is in this compressor the heat is removed from the gas with the help of pressure. The liquid refrigerant is passed through the evaporator coil, and the coil helps to convert the liquid into cool air, which is then circulated into the environment.
All home heating and cooling systems can be categorized into 4 types of HVAC systems. Once you decide which HVAC unit is best for your home, you will want to compare air conditioner type and installation costs.
The list below represents the most popular types of HVAC systems and how they are most commonly combined to heat and cool the air in your home. Depending on if you need a new HVAC system installation or simply a replacement of either unit for heating or cooling, you will need to know the basics components that can make up an HVAC unit. Split HVAC units have two main systems one dedicated to cooling your home and one dedicated to heating your home.
They usually contain one indoor unit such as a furnace found in a garage, utility closet, crawl space, garage, attic, or basement and one outdoor unit such as a central air conditioners often located outside on a flat cement foundation called an AC pad. It is easy to replace the existing duct system without doing minor or no modifications. They are highly energy efficient in areas that require less heating or cooling. Con: The forced air system may disperse dust and allergens around your home, and it might also disperse your kitchen odor to the parts of your home.
The system also requires ductwork, which may be expensive for homeowners. Find Local Pros. Call to speak with a dealer.
