Signs You May Need HVAC Repair or Replacement

An HVAC system that's malfunctioning or outdated likely needs professional attention for maintenance or replacement. Watch for these signs 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 are often a good option for smaller homes. Packaged systems consist of a single heating and cooling unit, normally located in an attic or basement. This unit tends to be efficient, compact, and easy to maintain.

HVAC maintenance costs differ depending on the particular service needed. HVAC systems are complex and might require different kinds of maintenance. Fees for some common services are as follows:

Ways to Save Money on HVAC Costs

Repairing or replacing your HVAC system when needed is important, but can be expensive. Fortunately, there are actions you can take to reduce gradual wear and tear on your system.

• Change the position of your blinds seasonally. Closing your blinds in the summer blocks some passive solar heat from getting indoors. Opening the blinds in the winter allows this same heat to help warm your home. Both of these measures help decrease the work required from your house's HVAC system.
• Change filters regularly. Replacing your air filters or washing them every 1–3 months allows effective air circulation through your system. You should also try to keep debris from accumulating on the external parts of your HVAC.
• Keep your system clean. Keeping your condenser fan blades, grills, ductwork, and indoor evaporator coil clean helps your HVAC system function properly and lowers your risk of mold. The National Air Duct Cleaners Association suggests cleaning your HVAC when you notice it starting to get dirty.
• Monitor for potential problems. Keep an eye on your system for issues, for example by consistently checking your thermostat and energy bills. This allows you to address 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 installation or repair. Established providers with certified technicians can offer assurance your HVAC system will deliver consistent heating and cooling year-round.

Compare Multiple Bids

Request estimates from three or more HVAC providers. Describe your issues and ask if technicians can inspect your system in person. Review each company's diagnoses, recommended solutions, estimated cost, warranties, and timeline. Avoid providers that pressure you or demand payment before work.

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, individuals must pass an exam (the specific exam depends on the 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.

HVAC contractors in Texas 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 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 a company's reviews and complaints on sites such as the Better Business Bureau (BBB), Yelp, and Google Reviews. Pick a company with positive feedback and good customer testimonials.

Understand Work Details

Always make sure you understand what a company’s process is like. When HVAC repairs are needed, ask your provider to explain which parts need replacement and explain why. Confirm that your technician will clean and test the full system afterward to ensure proper operation. When replacing your HVAC system, ask your contractor to provide details on the new features, brand, energy efficiency, estimated installation time, and model. Before signing a contract, make sure you understand how your provider will properly size the new unit for your home and what the cost will be.

Compare Warranties

Trustworthy HVAC companies provide warranties for their work. Broader coverage is better, so make sure to review warranties between providers. Choose the one that gives you the most coverage at a fair cost.

Get Quote in Writing

Always get quotes for HVAC service in writing before committing to a provider. A comprehensive quote should cover both materials and labor. Make sure you review all terms before signing a contract.
