10 Best HVAC Companies in Ashburn, VA

Signs You May Need HVAC Repair or Replacement

If your HVAC system is broken or getting old, it likely needs servicing or replacement from an HVAC company. Look for these signs your system needs service:

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

Book an inspection if you notice any of these issues. A local technician can inspect your system, detect problems, and decide whether you need repairs or a new HVAC unit.

Cost of HVAC Installation and Maintenance in Ashburn

HVAC installation or maintenance costs change depending on your system. Common HVAC unit types include the following:

• Split or mini-split: If your home's ductwork isn’t suited for a central HVAC system, you probably have a split or mini-split system. Split systems have interior units in each room to control temperature. These indoor units all connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions much like a standard split system, but is able to utilize either electricity or gas as energy sources.
• Heat pump: Heat pumps exchange warm and cool air between your home and the outside. These systems don't produce their own heat or AC, so they work better in moderate climates.
• Packaged heating and air: Packaged HVAC systems are good for smaller homes. They consist of a single heating and cooling unit that's typically located in an attic or basement. This unit tends to be compact, efficient, and easy to maintain.

HVAC maintenance costs vary based on the specific services needed. 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

It's important to take care of HVAC repairs and replacements in a timely manner, but it can also be expensive. Thankfully, there are some steps you can take to slow the wear and tear on your HVAC.

• Change filters regularly. Air flows most effectively through your HVAC system when you change out or clean the filters every 1–3 months. Also avoid letting debris pile up on the outside areas of your HVAC.
• Change the position of your blinds seasonally. Keeping your blinds open in the winter helps you take advantage of passive solar heating. Keeping them closed in the summer helps keep some of this heat out. Both of these measures help reduce the strain on your HVAC system.
• Monitor for potential problems. Monitoring your system for issues — 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. Keeping your ductwork, indoor evaporator coil, condenser fan blades, and grills clean helps your system run and reduces the chance of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system whenever it begins to look dirty.

How To Choose a Local HVAC Company

Knowing the indicators of a good HVAC company is important. Working with a contractor that's properly licensed and highly experienced will give you confidence that they can keep your system running efficiently, providing you with effective heating and cooling in your home.

Compare Multiple Bids

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

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 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 on a state-by-state basis.

In Virginia, HVAC contractors need to 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

You should also check a company's reviews and complaints on sites such as Google Reviews, the Better Business Bureau (BBB), and Yelp. Pick a company with glowing feedback and stories of satisfied customers.

Understand Work Details

Always make sure you understand the details of a planned project. When HVAC repairs are required, your provider should detail which parts need replacement and why. Confirm that your technician will clean and test the system after repairs are done to verify that it’s working properly. When replacing your HVAC system, ask the contractor to provide details on the new energy efficiency, features, 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

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

Get Quote in Writing

Get written quotes before starting any HVAC work. The quote should cover costs for both labor and materials. Read all terms carefully before signing.
