10 Best HVAC Companies in Sterling, VA

Signs You May Need HVAC Repair or Replacement

If your home's HVAC system isn't working correctly or suffering from a lot of wear and tear, you may need to hire an HVAC contractor for repairs or replacement. Watch for these common signs that your system needs professional attention:

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

If you're experiencing any of these HVAC issues, we recommend having a technician inspect your system. A local professional can detect problems and decide whether fixing or replacing your HVAC unit is the best solution.

Cost of HVAC Installation and Maintenance in Sterling

The price of HVAC installation or maintenance changes 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 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 performs similarly to a standard split system, but is able to utilize either electricity or gas for power.
• Heat pump: Heat pumps transfer warm and cool air between your house and the outdoors. They don't make their own heating and cooling, so they work more efficiently in more moderate climates.
• Packaged heating and air: Packaged HVAC systems are a smart choice for smaller houses. They have a single heating and cooling unit, typically in an attic or basement. This unit is often space-saving, cost-effective, and easy to maintain.

HVAC maintenance prices vary based on the specific services required. HVAC systems can be complicated and potentially require several different services. Price ranges for typical jobs are as follows:

Ways to Save Money on HVAC Costs

HVAC upkeep is important, but can be pricey. Thankfully, there are steps homeowners can take to reduce wear and tear on their HVAC and lower future maintenance needs.

• Change filters regularly. Cleaning or replacing your air filters every 30–90 days helps air flow efficiently through your system. You should also try to keep debris away from the outside areas of your HVAC system as much as possible.
• 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 colder months helps warm your home with passive solar heating. Closing the blinds during the summer helps prevent the same heat from getting inside. Doing both helps decrease the strain on your HVAC system.
• Keep your system clean. Keeping your indoor evaporator coil, ductwork, grills, and condenser fan blades clean helps your system run and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.

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

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

Check Credentials

Look for an HVAC company that employs qualified technicians with the necessary training and licenses. In all states, HVAC contractors must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory 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 the type of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled on a state-by-state basis.

In Virginia, HVAC contractors must have a contractor license with an HVAC specialization from the Department of Professional and Occupational Regulation. A valid Master HVAC Tradesman License (which has its own experience and education requirements) is necessary to apply. Licenses be class A, B, or C.

• Class A: Contractor has at least five years of experience and can work on projects valued over $120,000
• Class B: Contractor has at least three years of experience and can work on projects valued between $10,000 and $120,000
• Class C: Contractor has at least two years of experience and can work on projects valued under $10,000

Always check a provider's reviews and complaints with organizations such as the Better Business Bureau (BBB), Google Reviews, and Yelp. Choose a provider with positive reviews and a history of good customer service.

Understand Work Details

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

Compare Warranties

A trustworthy HVAC company will back its repair services and installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully review warranty terms for each contractor and choose the company that provides the most protection at a reasonable price.

Get Quote in Writing

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