In the extreme heat of 100°F in Dallas-Fort Worth, a properly installed HVAC system ensures reliable cooling. The energy efficiency that comes with a proper installation is also essential for managing your electricity bills and the long lifetime of the system.
HVAC units not only have to be powerful for the heat, but also manage the high humidity of the metroplex. Temperature fluctuations, dust, and pollen create additional challenges for the system.
Therefore, you need to select and install a system that can overcome this challenge and deliver the benefits you are investing in. In this post, I’ll provide a full guide for HVAC selection and installation in Dallas-Fort Worth.

Understanding HVAC Systems
Efficient cooling starts with selecting the right unit. Different HVAC systems are built for different scenarios. In this section, we will cover different HVAC systems and their components to give you a general idea about them.
Types of HVAC Systems
- Split/Central HVAC Systems: This is the most common HVAC type used in DFW homes. A central AC + furnaces with air handlers form this type of system. There are indoor and outdoor units for temperature regulation, and the air handler distributes the air.
- Packaged System: All air conditioning and heating components are packaged in one outdoor unit in these systems. Homes with limited indoor space greatly benefit from these systems.
- Ductless Mini-Splits: Ductless mini-split systems have individual indoor units that are connected to an outdoor compressor. Sometimes, you can link several indoor units to one outdoor unit. Mini-splits are a good option for zoned heating and cooling.
- Heat Pump Systems: Unlike the split systems, heat pumps provide heating and cooling with a single system. Instead of directly heating or cooling the air, they also transfer the heat in and out of your homes. Heat pumps are ideal for mild climates.
- Hybrid HVAC Systems: Sometimes, a heat pump is combined with a gas furnace or other heating equipment (as a backup) that serves as the central HVAC system. They are good for mild to moderate winter climates and can save a lot of energy for the DFW climate.
| System Type | Best For | Pros | Cons |
| Central AC + Furnace | Most DFW homes | Powerful cooling, reliable heating | Higher upfront cost |
| Heat Pump | Mild winters | Energy-efficient, dual heating/cooling | Struggles in extreme cold |
| Ductless Mini-Split | Older homes | No ductwork needed, zoned cooling | Higher per-unit cost |
Key Components of the HVAC System
Depending on the system, there can be different components of an HVAC system. The most common of them are:
- Condenser & Compressor: This is the outdoor unit that releases or gathers heat.
- Evaporator Coil: It is the indoor unit that takes heat from the indoor air.
- Blower/ Air Handler: The blower fan moves the air through the system.
- Vents/Registers: These are the visible covers you see on walls, floors, or ceilings where air enters or leaves a room.
- Ductwork: Usually a network of tubes that distributes the conditioned air.
- Filters: Filters are often placed at the inlet (vents/registers) or air handlers. They remove the dust, pollen, and debris from the air.
- Thermostat: The device that measures the existing temperature, and sets and regulates it.
- Refrigerant lines: Tubes that carry refrigerant between indoor and outdoor components.
Factors to Consider Before HVAC Installation in DFW
No installation is a one-size-fits-all solution. Depending on your needs, your building’s needs, and the environment you live in, you would want different approaches.
1. Climate & Weather Consideration
The Dallas-Fort Worth Metroplex experiences:
- Extreme summers crossing 100°F
- High humidity for mold growth and discomfort potential
- Mild but unpredictable winters with occasional freezes
A high-efficiency central AC unit with a gas furnace or a heat pump with a backup heat source is the best fit for these conditions.
2. Home Size & Layout
The bigger the home, the powerful your AC needs to be. The AC capacity is usually measured in tons.
However, don’t pick an oversized unit (higher ton than your space). It will waste too much energy. An undersized AC (lower capacity than required), on the other hand, will short-cycle frequently.
If you have a two-story home, it can benefit greatly from zoning systems (separate temperature control with the same system. Or, you can use dual units to balance the airflow.
Older homes often need ductwork sealing, modifications, or replacement to keep up with newer units.
3. Energy Efficiency Ratings
There are different standards for efficiency depending on the type of HVAC unit:
- SEER: It is the efficiency scale for a cooling unit. Higher SEER units are more efficient. (The unit gets more expensive, too)
- HSPF: HSPF is the measurement of a heat pump’s efficiency. DFW homeowners should get an HSPF rating above 7.5 for their homes.
- ENERGY STAR Certification: It is given to independently tested and verified units that meet the strict energy efficiency guidelines set by the EPA. The certification ensures maximum efficiency and potential rebates.
4. Humidity Control Features
For being in a humid subtropical climate, DFW experiences 60-70% humidity levels on average throughout the year. Usually, HVAC systems have some humidity control features. However, this high humidity is often a burden for most HVAC systems.
HVAC units with variable-speed compressors can continuously adjust their speed and bear the runtime load from high humidity. Besides, the continuous and slower operation removes more moisture compared to traditional systems, where they just turn on and off.
You can also consider getting additional whole-home dehumidifiers. A dedicated dehumidifier is more precise and has independent control of the indoor humidity.
5. Local HVAC Codes & Permits
Some DFW cities (Dallas, Fort Worth, etc.) require HVAC installation permits. Most cities adopt codes based on International Code Council (ICC) standards.
There are also some rebates available:
- Oncor offers rebates for high-efficiency systems
- Federal Tax Credits are available for ENERGY STAR systems
Choosing the Right HVAC Contractor in DFW
For the best comfort and efficiency in DFW’s extreme heat and humidity, you need precise system sizing and installation. A qualified contractor does the job for you. Besides, a good service provider makes sure the installation maintains the local codes for safety, rebates, maintains warranties, and avoids costly issues.
Here’s what to look for in an HVAC installer:
- TACLB license and insurance for general liability

The HVAC Installation Process in DFW
Proper installation starts way before setting up the unit.
Pre-Installation Assessment
Some DFW-specific considerations before any HVAC installation are:
- Manual J Calculation for proper sizing (to tackle the extreme DFW heat)
- Ductwork Inspection (to check the suitability of older homes)
- Permit Check (for cities like Dallas, Fort Worth, and Plano)
If applicable, you may also need:
- Removal of the old unit
- Ductwork modifications
R-22 refrigerant was banned in 2020. If you are still using a system that uses R-22, a replacement is mandatory. Ductwork modifications are needed for sealing leaks, adding insulation, or zoning adjustments.
When you contact a professional, he will-
- Evaluate home size, insulation, and airflow needs
- Discuss different system options (e.g., heat pumps vs. AC and furnace)
- Provide a written estimate and timeline
- Safely dispose of older units, maintaining EPA requirements
Installation Day
After the initial assessments, the actual installation takes place. The entire process takes 4-12 hours, depending on the complexity of the ductwork. Sometimes, it may take longer due to attic work, permit delays, or unexpected issues like outdated electrical connections.
On the installation day, you can expect the following steps:
1. Outdoor Unit Placement
To protect the condenser from the sun, it should be shaded. However, the shade shouldn’t obstruct the airflow. Technicians may also install additional concrete pads or brackets to keep the unit at a level away from debris.
2. Indoor Unit Installation
In DFW, attics are most commonly used for the location of air handlers and ductwork. The technician has to make sure there is proper ventilation in there. Otherwise, it will cause overheating in both the space and the equipment.
Furnaces often go in a closet. It has to maintain clearance codes in that case.
3. Refrigerant Lines & Electrical
If a replacement is necessary for refrigerant lines (like older ones), the technician will cut off the line and remove the remaining refrigerant. After setting up the new refrigerant line, he will charge the system to a proper level.
If you have undersized wiring (like many older DFW homes), old connections and thermostats are removed to put a new system in place. The key electrical components installed/checked are:
- Disconnect box (near outdoor unit)
- 240V circuit (for AC/heat pumps)
- Low-voltage wiring (to connect the thermostat to the indoor unit)
- Emergency shutoff switch
4. Thermostat and Zoning Setup (If Required)
It’s recommended to get smart thermostats for maximum savings and comfort. A smart thermostat can adjust to DFW’s temperature fluctuations automatically. That makes the job a lot easier.
Most DFW homes also have a hotter upstairs (in two-story homes). It happens due to heat rising upwards. Zoning is a good way to control different areas in the home (having two settings for two requirements).
Post-Installation Checklist
Just installing an HVAC system isn’t enough. You can notice some common problems, like hot or cold spots, in your home. A technicians need to perform some post-installation checks to make sure you don’t get into any more trouble.
Here’s what a professional does:
- Check refrigerant charge
- Test airflow
- Calibrate and recalibrate the thermostat
- Test duct pressure
- Correct permitting paperwork
- Inspect the safety of electrical and refrigerant
- Demonstrate basic DIY maintenance and operation
- Online registration for warranty

Maintaining Your HVAC System in DFW
Dallas-Fort Worth’s climate is extreme and can change rapidly. High SEER units can somewhat bear the load, but the high demand always puts extra pressure on your HVAC system.
Maintaining it seasonally and from time to time is necessary to make sure your system is ready to handle the load. And if any issues can cause problems, you can act accordingly to prepare.
You should always get two professional tune-ups/checkups a year for your HVAC system:
- Spring: To prepare your AC before summer
- Fall: To prepare your furnace/heating equipment before winter
Professionals also have the right knowledge and equipment to detect issues that DIY checkups can’t. So, consider enrolling in a professional plan to get your system checked on time. You can also reap the other benefits these services offer with their maintenance plans.
Also, don’t forget to change (or clean if applicable) your filters every 1-3 months. Otherwise, the high levels of pollen and dust in the DFW environment will easily clog that up.
Some Common HVAC Problems in DFW
- Overworked AC Units: Usually happens with an undersized system, which struggles to keep up. Get a professional estimation before purchasing your product to avoid this problem.
- Duct Leaks: Use duct tape or sealant to cover the minor leaks. Get professional help if the leak is too large.
- Refrigerant Leaks: Get regular checkups to avoid this problem. Professionals will always check the refrigerant levels. If there are leaks, he should be able to identify it with the loss of refrigerants.
- Thermostat Malfunctions: Keep thermostats away from direct sunlight or heat-generating appliances. You can also go for a smart thermostats that adjusts on its own to avoid any calibration issues.
