The average HVAC replacement cost is $3,250 to $12,586, which would include installation of both a new central AC unit and gas furnace combo. If you need to replace ductwork as well, you can expect an additional $1,875 for a single story 2,200 sq. Air conditioner installation: $1,800 to $10,500. Gas furnace installation: $1,800 to $4,000. Heat pump installation: $2,900 to $6,000. Again, these costs will vary depending on your home and the HVAC unit being installed. For accurate pricing, contact an HVAC professional in your area.

When looking to install a new HVAC system in your home, it is important to make sure it is sized correctly. If it is too small, it might not be able to regulate the temperature of your whole home. On the other hand, an oversized unit will not work as efficiently, may wear out faster, and possibly have dehumidification problems. The process involved in determining the right size air conditioner and furnace for your home is a very complicated process, but it is possible to do a general estimate on your own.
To determine the approximate size of your HVAC system, use the following calculations:
- First, determine square footage: Find out the floor space in your home. You might be able to find the number written down somewhere, or you might have to measure it yourself. To measure a room on your own, use a tape measure to determine the length and width. Multiply those together for the square footage for that room. Repeat the process for each room and hallway, then add them all together.
- Second, determine the base BTU: The unit used to measure energy used for heating and cooling is the British Thermal Unit, or BTU. The approximate amount of energy used to cool a square foot of your home is roughly 25 BTUs, so multiply the number of square feet in your home by 25 to get the base BTU measurement.
- Third, account for high ceilings: If your home’s ceiling is over 8 feet, multiply the base BTU amount by 1.25, or 25%.
For a 1500 square foot home with normal ceilings, the result would be about 37,500 BTUs. Once you have the base BTUs figured for your home’s size, you can then figure out the size of AC and heating units you need. For the air conditioner, divide the number by 12,000 to determine the tonnage required. For the furnace, divide the BTU by the unit’s efficiency as a decimal.
In the case of a 1500 sq. ft. home, the air conditioner would need to be 37,500 ÷ 12,000, which comes out to about 3 tons. For the furnace, an 80% efficiency unit would need a BTU output of about 37,500 × 0.8, which is about 47,000 BTU.
Manual J: The Professional Method
Of course, these are very basic calculations, and they do not take into account the number of people in the building, the climate of the area, the number and placement of windows, whether those windows face north or south, the amount/type of insulation in the walls, lighting placement, and multiple other factors.
For more precise measurements, professionals will use the Manual J calculations, which take all of these factors into account. This allows the technician to know exactly what size HVAC to install in your home for optimum comfort and efficiency. A properly trained HVAC professional will be able to make the proper measurements and design a system that meets your home’s climate control needs. At Climate Tech Air Conditioning and Heating, we provide the needed expertise to make sure your home’s temperature is well regulated year round.

First of all, let’s start with the most basic question someone could have around an HVAC installation… What does HVAC stand for?
The acronym “HVAC” stands for heating, ventilation and air conditioning.
Central HVAC systems include a variety of components and equipment, all of which must be installed properly to work in perfect synchronization. Failure to follow industry standards during HVAC installation can result in poor performance, higher energy bills, and shorter service life.
Let’s discuss the different elements that play a role in any HVAC installation:
HVAC Unit Size
Whether it’s a straight cool system, a package unit, or a heat pump that provides both heating and cooling, nothing is more important to a successful installation than getting the system size right. An oversized unit not only costs more to purchase but will warm or cool your home so quickly that it will cycle off before household air has had time to return to the equipment for re-conditioning. This can cause the air to feel musty, sticky or clammy and can create uncomfortable warm or cold spots in your home and bottom-line reduce the efficiency of your HVAC unit.
Undersized systems simply don’t have enough power to get the job done efficiently. A too-small system will need to run longer to achieve ideal temperatures, which can result in costly repair and premature replacement. HVAC systems are sized according to the amount of heating and cooling that they generate. A reputable HVAC technician will conduct a load calculation that considers factors like your home’s construction, size, design layout, and orientation in order to establish the correct system size.
Heat Pump vs Straight Cool or Package Unit
The difference between a heat pump, a straight cool, and a package unit, is a heat pump unit goes into reverse to cool. Heat Pumps are great in all climates but can be tricky in the extreme cold if they’re not properly installed. They can overheat easily, causing the system to go into a bypass mode and temporarily stop heating the house. To prevent this, electric heat strips are installed in the system as a secondary source, so the heat pump doesn’t have to work so hard.
Package units are a little more simplistic and have a faster installation time. A package unit is the whole “package” because it heats, cools, and circulates air from a single rooftop unit. These are most popular for commercial buildings.
Straight Cool Split Systems are the most common for residential homes. The condenser, furnace, and coil are all separate components that work together to regulate the temperature. The condensers will most commonly be located on the ground unless the house was specially designed to keep the condensers out of sight on the roof. These systems work efficiently to keep houses at just the right temperature.
Forced-air heating and cooling systems rely on a branching network of air ducts to circulate conditioned air throughout your home. For optimal performance, the return and supply channel or duct must be carefully installed and balanced. Over time, poorly designed or improperly maintained ductwork can develop leaks and gaps that impair the efficiency and produce poor air quality. According to the Environmental Protection Agency (EPA), up to 20 percent of the air that travels through ductwork in the average home is lost to leakage.
Sealing and insulating ducts eliminate leaks and improves energy efficiency. In order not to disrupt the balance between supply and return ducts, however, it’s best to leave the task in the hands of qualified HVAC technicians. Improper sealing can actually worsen system efficiency.
Thermostats and Controls
Thermostats are connected to sensors on HVAC equipment that signals the system to turn off or on according to the thermostat’s temperature setting readings. For proper operation, both the thermostat and the indoor HVAC equipment should be installed in a draft-free location away from air ducts.
Programmable thermostats allow you to preset different temperatures for different times of the day. If you are looking for energy efficiency by scheduling your HVAC system to adjust temperatures while you’re away from home or asleep at night, you can reduce your energy expenses by 10 percent or more, according to the EPA. Some advanced models let you control settings from your computer or smart device.
Today’s high-efficiency furnaces and air conditioners come with features like variable-speed blowers that automatically adjust to the changing heating and cooling demands of your residential or commercial HVAC. Instead of constant off-and-on operation, they execute a consistent delivery of warmed or cooled air while conserving energy at the same time.
HVAC Installation Costs
Factors that Affect your HVAC Installation Costs
Factoring the cost of a new unit breaks down to many things. It’s not just as simple as picking out a unit and having someone install it. Technicians look to see if the house is up to city code to be able to perform an installation, considers additional electrical needs, and checks to see if the ductwork is in usable condition. Along with the ductwork inspection, technicians will also calculate to see if a second return will be needed. A new unit is no good if it continues to break down after being starved for air.
There are other factors to think about as well, such as will a crane be needed, do the condensate lines need to be replaced, are there obstructions in the backyard or on the room that the installation team would have to move or workaround? While it’s easy to think that a simple quote shouldn’t be so pricey, there’s actually a lot more to it.
