Signs You May Need HVAC Repair or Replacement

An HVAC system that's not working properly or outdated likely needs professional attention for repairs or replacement. Watch for these indicators that your system needs service:

• Unusually high energy bills
• Refrigerant leaks
• Frequent breakdowns and need for repairs
• Poor air circulation or uneven heating/cooling
• Odd noises when the system turns on
• Thermostat malfunctions or temperature control issues
• Cracking, corrosion, or rust
• An HVAC system that's over 15 years old

These HVAC red flags indicate that you should have your system evaluated. A local technician can complete an inspection, identify problems, and advise you whether you should repair or replace your HVAC unit.

Cost of HVAC Installation and Maintenance in Duncanville

The cost of HVAC installation or maintenance varies depending on the kind of unit you have. Common types of HVAC units include the following:

• Split or mini-split: If your home doesn’t have the ductwork for central air or heating, you probably have a split or mini-split system instead. Split HVAC systems have indoor units in each room to control temperature. These connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system operates similar to a normal split system, but has the advantage of being able to utilize energy from either gas or electric sources.
• Heat pump: Heat pumps transfer warm and cold air between your home and the outdoors. They don't generate their own heat or AC, so they function best in mild climates and may not be as effective during Duncanville's hot summers.
• Packaged heating and air: Packaged HVAC systems work well in smaller houses. They consist of a single combined heating and air conditioning unit, typically located in a basement or attic. This unit is typically space-saving, energy-efficient, and easy to maintain.

HVAC maintenance costs differ depending on what services are needed. HVAC systems are complicated and may require different kinds of maintenance. Costs for some common services are as follows:

Ways to Save Money on HVAC Costs

It’s important to take care of HVAC repairs and replacements when they are required, though they can be expensive. The good news is that homeowners have ways to minimize progressive deterioration and reduce the frequency of breakdowns.

• 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 in warmer seasons helps prevent the heat from getting inside. Doing both helps decrease the demand on your HVAC system.
• Change filters regularly. Replacing or cleaning your air filters every 1–3 months helps air flow smoothly through your system. You should also try to keep debris away from the external sections of your HVAC system as much as possible.
• Keep your system clean. Keeping your condenser fan blades, grills, ductwork, and indoor evaporator coil clean enables your HVAC system to function effectively and lowers your risk of mold. The National Air Duct Cleaners Association suggests cleaning your home's HVAC system when you notice things starting to get dirty.
• Monitor for potential problems. Monitoring your system for issues — for example, by checking your thermostat and energy bills routinely — helps you catch issues before they get too expensive.

How To Choose a Local HVAC Company

Knowing the indicators of a reliable HVAC company is key for a smooth repair or installation. Picking an established business with certified technicians gives you assurance your HVAC system will deliver consistent coolig and heating year-round.

Compare Multiple Bids

Contact at least three HVAC providers for quotes. Describe the issues and have technicians visit to inspect your HVAC system if possible. Compare the providers' explanations, solutions, estimated costs, warranties, and timeframes. Avoid companies that pressure you or demand payment upfront.

Check Credentials

It's important to choose an HVAC company that employs technicians with the appropriate qualifications and expertise. HVAC contractors in all states have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, an individual must pass an exam (the type of exam depends on what kind of equipment they plan to work with). Section 608 certification is required for all technicians who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." All other licensing requirements are handled on a state-by-state basis.

In Texas, HVAC contractors must be licensed by the Texas Department of Licensing and Regulation. Contractors need to have at least four years of experience within the past six years and must provide 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. Registered and certified technicians must both be supervised by a licensed contractor. You should also check reviews and complaints on sites like Google Reviews, Yelp, and the Better Business Bureau (BBB). Choose a company with glowing reviews and testimonials about great customer experiences.

Understand Work Details

Always make sure you understand the details of a planned project. For HVAC repairs, your provider should list which parts require 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, request that the installation company describe the new features, estimated installation time, brand, model, and energy efficiency. Before signing a contract, ask about the process your provider will use to properly size the new system for your home and how much it will cost.

Compare Warranties

Good HVAC companies offer warranties on service and installations. The more complete the coverage, the better. Review warranty details between providers and pick the one that offers the most comprehensive protection within your budget.

Get Quote in Writing

Get written estimates before starting HVAC work. The quote should include costs for both labor and materials. Review all terms carefully before signing.
