On average, an HVAC system can last between 10 to 25 years with preventative maintenance. The life expectancy of any HVAC system or equipment depends on the preventative maintenance and service performed as well as the type of equipment and your usage.

Pricing depends on the size of your house, the brand and efficiency rating of your new HVAC unit, the length of your ductwork, and labor expenses. Replacing your HVAC system costs between $4,820 and $9,350 and takes about a day to complete. A change-out is simply replacing out the main components of your HVAC system without any new ductwork.

The average cost to replace ductwork is $1,400 to $5,600 or $25 to $55 per linear foot for materials and installation. A typical home needs 30 to 90 linear feet of ducting. Ductwork lasts 10 to 20 years on average before it needs replacing. New ducts are higher efficiency and produce better air quality.

To calculate a fair HVAC installation cost, you need to determine two things. First, the price of the equipment you’re installing based on your required size of AC, size of the furnace, desired SEER value, and desired AFUE value. And second, the labor costs and installation supplies such as sheet metal, refrigerant, a thermostat, AC pad, and a line set.

You should replace your HVAC system if:
- Your AC is older than 10 years old, and the HVAC repair bill would be
more than 30% of the cost of a new AC unit.
- Your power bills keep going up and up.
- Your house is dusty, and the air quality seems poor.
- You can’t maintain a comfortable temperature in your home.
- Odd smells and sounds are emanating from the units.

A regular HVAC tune-up typically costs $50 to $200 and should be performed yearly. HVAC maintenance contracts cost $150 to $300 per year, and you’ll get an annual maintenance visit, one included service call, a discount on parts, and usually some other benefits.

HVAC stands for Heating, Ventilation, and Air Conditioning.

The components that make up an HVAC system are generally the same.

The furnace. The furnace moves air from the heat exchanger into the air ducts.

The heat exchanger. The heat exchanger is not part of the furnace. It’s located inside the furnace, but operates independently by adding heat to the incoming air from the combustion chamber.

The evaporator coil is also in the furnace, but has a different job to do. When air runs through the evaporator coil, the coil absorbs heat and adds refrigerant. The now-cold air blows through the air ducts throughout your home.

The condensing unit. The condensing unit is like the evaporator coil but for an outdoor HVAC unit. Unlike the evaporator coil, the condensing unit gives off heat.

The refrigerant tubes. These metal tubes connect the evaporator coil with the condensing coil. This means the refrigerant tubes connect the indoor and outdoor HVAC units. The tubes contain cooling refrigerant under a wide range of temperatures.

The thermostat. This is the part of the HVAC system that you control to adjust the air conditioning or heating system or turn the system on or off. This small appliance is typically on a wall of the main level of your home. A programmable or “smart” thermostat can fine-tune your home’s temperature even if you’re not there, and be accessible through an online app on a computer or mobile device .

The ductwork.The air ducts move air throughout your home. Air comes into the HVAC system through certain sections and is distributed to rooms through other sections. The vents. As the air travels through the ductwork, it enters the room through vents. Rectangular covers on the floor or ceiling direct and take in air.
The heat pump. During warmer months, the heat pump takes heat from the inside to the outside. During the colder months, it does the opposite.

All new appliances are assigned a SEER rating (Seasonal Energy Efficiency Ratio), which measures the energy efficiency of all HVAC systems. The higher the SEER number, the more efficient it is at heating and cooling in different temperatures.

Energy Star products have the backing of the US Environmental Protection Agency (EPA), ensuring that these products/appliances deliver better indoor air quality, protect our climate, and save money, as well as energy.

A home or business can receive a certification if all systems are built using Energy Star products, and federal and local rebates are offered on specific Energy Star units.

To choose what size air conditioner is right for you, you need to first calculate size of the home spaces served by the air conditioner, in square feet.

To calculate the size, simply multiply the length times the width of the room or area to be cooled. Then, as a practical number, multiply that total times 25 BTU. This allows ample cooling, whether it is a rainy, moist day or a hot, sunny, humid day. Let’s say the room is 12 feet wide by 15 feet long. That means 12x15=180 square feet. Take the 180 sq. ft. times 25 BTU per square foot and you get the minimum BTU air conditioner you should buy. That means 180x25=4500 BTU cooling capacity is needed.
