10 Best HVAC Companies in Sunnyvale, TX

Signs You May Need HVAC Repair or Replacement

An HVAC system that's malfunctioning or outdated likely needs professional attention for repairs or replacement. Watch for these signs that your system needs service:

• Temperature control issues or thermostat malfunctions
• Higher than normal energy bills
• Refrigerant leaks
• Strange noises when the system turns on
• Poor air circulation or uneven heating/cooling
• Frequent breakdowns and need for repairs
• Rust, corrosion, or cracking
• 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 determine whether repair or full HVAC replacement is required.

Cost of HVAC Installation and Maintenance in Sunnyvale

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

• Split or mini-split: If your home doesn't have the right ductwork for central air or heating, you likely have a split HVAC system. Split or mini-split systems consist of interior units that regulate the temperature in individual rooms, and that are all connected 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 draw on either electricity or gas for energy.
• Heat pump: Heat pumps transfer warm and cold air between your home and the outdoors. They don't make their own heat or AC, so they perform best in temperate climates and may not be as effective during Sunnyvale's hot summers.
• Packaged heating and air: Packaged HVAC systems are often a good option for smaller homes. They consist of a single combined heating and cooling unit that's typically located in a basement or attic. This unit tends to be efficient, compact, and easy to maintain.

HVAC maintenance costs differ based on the specific services required. HVAC systems can be complicated and potentially require a number of services. Fees for typical jobs are as follows:

Ways to Save Money on HVAC Costs

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

• Change filters regularly. Cleaning or replacing your air filters every 30–90 days 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.
• Monitor for potential problems. Monitoring your system for problems — for example, by checking your thermostat and energy bills regularly — helps you get ahead of problems before they get too expensive.
• Keep your system clean. Regularly cleaning condenser fan blades, ductwork, indoor evaporator coil, and grills helps keep your HVAC system running efficiently and reduces the risk of mold. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.
• 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 same heat from getting inside. Doing both helps decrease the strain 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 give you peace of mind and ensure your system provides reliable heating and air conditioning for your home.

Compare Multiple Bids

Contact at least three HVAC companies for quotes. Describe your issues and schedule an in-person inspection if possible. Compare contractors' diagnoses, suggested repairs, estimated costs, warranties, and timeframes. Avoid providers that pressure you or demand upfront payment.

Check Credentials

Look for an HVAC company that employs qualified technicians who have the necessary training and licenses. In all states, HVAC contractors need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for all technicians who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." Contractors 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 need to have at least four years of experience in 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. You should also check a company's reviews and complaints with organizations such as Google Reviews, Yelp, and the Better Business Bureau (BBB). You want to hire a company with glowing reviews and stories of positive service experiences.

Understand Work Details

Always make sure you know the details of a planned 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 finished to verify that it’s working properly. When replacing your HVAC system, ask your installation company to provide details on the new features, energy efficiency, brand, model, and estimated installation time. Before work begins, make sure you understand the process your provider will use to select the correctly sized system for your home and what the cost will be.

Compare Warranties

Trustworthy HVAC companies stand behind their services with warranties. Look at warranties from different companies, while remembering that more comprehensive coverage is better. Look for the provider that offers the most coverage for a reasonable price.

Get Quote in Writing

Always get HVAC quotes in writing before work begins. A detailed quote will cover costs for both materials and labor. Confirm that you agree to all terms before signing the contract.
