New HVAC System Cost for Your Conroe, Texas Home

The average lifespan of an HVAC unit is around 15 years. With regular maintenance and replacements, this can go even further. But when your system finally gives up, do you know how much a replacement will set you back?

There are many variables, but we can help you get a rough idea. Below, we discuss the HVAC system cost.

HVAC System Cost

There is a huge range of variables that can impact a new home’s HVAC system cost. It depends on the size of the property, the type of system being installed, and the number of units required. If you need major works like new ductwork, this can go even higher.

The national average is around $7000 for a whole system. Replacing individual units will be much cheaper. However, for a full large property installation, you may be looking at $12,000 or upwards.

When Do I Need A Replacement Home HVAC System?

Your system will tell you when it needs replacing. Generally, this will be age-related. HVAC systems need replacing every 10 to 15 years, though this can be more with the right maintenance.

Once past this, you will find repairs become extremely regular, and it stops being cost-effective to get them done. Older systems that contain refrigerant may also not be repairable, as the chemical needed is no longer made.

Another sign is if you notice your heating and cooling bills begin to rise. If the system is old and parts break, it begins to work overtime to produce the climate you need. This results in more energy consumption, and it may be time for a more efficient model.

Factors Which Will Impact Price

Many factors will impact the final price. Below are the most common ones to keep in mind.

Unit Type

Units are the most vital part of your heating and cooling. The heart of this is the furnace, which will provide the heat. These can cost between $1000 to $4000. Always make sure that you consider how much you will save if you buy a more expensive but energy-efficient one.


The labor is the actual work required to install the system. If you have a new unit, then it can cost as little as $500. However, once large systems with ductwork become involved, it gets much higher and may require more than one worker.

The cost for this will always be included in the quote for a new system. Make sure you asked for an itemized breakdown to see how much it is costing.


Your old home HVAC system will need to be disposed of somewhere. Check to see how much the removal and disposal are. You may be able to do it yourself, but it will need taking to specialist places and could be extremely heavy.

Type of Installation

Access to the existing HVAC system will also play a part in the price. If it is difficult to remove the old one, this translates as more labor. In some cases, certain custom pieces may need to be made if spaces are small, tight or the building can not be altered, which also ups the cost.

HVAC System Unit Costs

Depending on the type of unit, once again, prices can vary. Most people can check their old unit and see what needs switching. However, some people may wish to change to more energy-efficient options.

  • Central AC Unit – $5000 to $9000
  • Ductless Split AC Unit – $2000 to $4000
  • Heat Pump – $5000 to $8000
  • Gas Furnace – $3000 to $4000
  • Oil Furnace – $5000 – $8000
  • Electric Furnace – $2500 to $3500

Keep in mind that you may need more than one of these. Ductless split AC units will need one in each room.


One part of the HVAC system that can add to the cost is ductwork. This allows heat and cool air to be transferred throughout your property.

If you have ductwork installed, it may need a repair or replacement. If you don’t, then ductwork can not be installed on every property so it may not be the right solution. However, it is a large task that involves lots of labor and disruption.

For some new systems, it may just be that alterations need to be made. These can cost anywhere between $2000 to $4000.

HVAC Replacement Types

There are three types of replacement when it comes to your home HVAC system. Each has its associated costs.

Change Out

An HVAC change-out is the most cost-effective option. It involves the replacement of a unit or major parts of the system without any work to the ducts. This usually takes around one to three days to complete and can cost anywhere between $4000 to $10,000.

Full Installation With Ductwork

This is a larger job that will take between three to six days, even on smaller properties. This increases if ductwork is being replaced, as you need to take the old out before putting the new in.

Costs can be anywhere between $6000 to $12000. However, new ductwork will increase air quality and energy efficiency, so is well worth the expenditure.

Full Installation With Extras

Several extra features may increase the cost of a full installation. A zoning system will take more time to install and could increase costs by $2000 to $3000. Humidifiers are something you may want to consider, along with SMART thermostats for increased control.
