10 Best HVAC Companies in Dallas, TX

Signs You May Need HVAC Repair or Replacement

If your HVAC system is broken or getting near the end of its lifespan, it likely needs servicing or replacement from an HVAC company. Look for these signs your system needs service:

• Refrigerant leaks
• Poor air circulation or uneven heating/cooling
• Odd noises when turning on
• Thermostat malfunctions or temperature control issues
• Higher than normal energy bills
• Rust, cracking, or corrosion
• Frequent breakdowns and need for repairs
• An HVAC system that's over 15 years old

If you notice any of the above, have a local HVAC technician inspect your system. They can diagnose problems and let you know whether repair or full HVAC replacement is the better solution.

Cost of HVAC Installation and Maintenance in Dallas

What you spend on HVAC installation or maintenance is determined by your system style. Common HVAC unit styles include the following:

• Split or mini-split: Homes without ductwork for central heating and cooling frequently have split or mini-split HVAC systems. These systems consist of interior units in each room to control temperature, which all connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC unit operates similarly to a regular split system. It provides flexibility by having the option to use either electricity or gas for energy.
• Heat pump: Heat pumps transfer hot and cold air between your home and the outside. These systems don't make their own heat or AC, so they work more effectively in moderate climates and may not be as effective during Dallas' hot summers.
• Packaged heating and air: Packaged HVAC systems are often a good option for smaller houses. They consist of a single heating and cooling unit that's usually located in an attic or basement. This unit tends to be efficient, compact, and easy to maintain.

HVAC maintenance prices vary based on the work needed. HVAC systems are complex and may need several types of maintenance. Prices for common jobs are as follows:

Ways to Save Money on HVAC Costs

Fixing your HVAC by repairing or replacing parts when needed is crucial, but can be expensive. Thankfully, there are steps you can take to reduce gradual wear and tear on your system.

• Keep your system clean. Keeping your grills, ductwork, condenser fan blades, and indoor evaporator coil clean helps your HVAC system function effectively and lowers the risk of mold. The National Air Duct Cleaners Association recommends cleaning your home's HVAC when you notice it starting to get dirty.
• Change filters regularly. Switching out your air filters or washing them every 30–90 days allows smooth air circulation through your HVAC system. You should also try to keep debris from accumulating on the outdoor sections of your HVAC.
• Monitor for potential problems. Monitoring your system for issues — for example, by checking your thermostat and energy bills regularly — helps you catch issues before they get too expensive.
• Change the position of your blinds seasonally. Leaving your blinds open during the winter helps warm your home with passive solar heating. Closing the blinds during the summer helps prevent the heat from getting inside. Doing both helps decrease the demand on your HVAC.

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is crucial for a successful project. Partnering with an experienced, licensed contractor can offer you peace of mind and ensure your system provides reliable heating and air conditioning for your home.

Compare Multiple Bids

Get quotes from at least three HVAC companies. Explain your issues and ask if specialists can inspect your system in person. Compare each provider's diagnoses, recommended solutions, estimated cost, timelines, and warranties. Avoid companies that pressure you or demand payment before work.

Check Credentials

Look for an HVAC company that employs skilled technicians with the necessary licensure and training. HVAC contractors in all states must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for all contractors who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." An individual must pass an exam (the type of exam depends on what kind of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled at the state level.

In Texas, HVAC contractors are required to be licensed by the Texas Department of Licensing and Regulation. Contractors must have at least four years of experience within the past six years and must show proof of insurance. An individual can also be a registered technician, which has no experience requirements, or a certified technician, which requires two years of experience. Both registered and certified technicians must be supervised by a licensed contractor. Reviewing feedback on Google Reviews, Yelp, the Better Business Bureau (BBB), and similar sites can help your decision. Choose a company with stellar reviews and reports of positive customer experiences.

Understand Work Details

Always make sure you know the details of any project. For HVAC repairs, your provider should list which parts need replacement and why. Confirm that your technician will clean and test the system after repairs are completed to verify that it’s working properly. When replacing your HVAC system, have the provider describe the new brand, energy efficiency, model, estimated installation time, and features. Before signing a contract, ask how your provider plans to accurately size the unit for your home and how much it will cost.

Compare Warranties

Reliable HVAC companies offer warranties on repairs and equipment installations. The more complete the coverage, the better. Compare warranty details between companies and pick the one that offers the most comprehensive protection for a fair price.

Get Quote in Writing

Always get HVAC bids in writing before work begins. A detailed quote will cover costs for both materials and labor. Ensure that you understand all terms before signing the contract.
