10 Best HVAC Companies in Alexandria, VA

Signs You May Need HVAC Repair or Replacement

A faulty or aging HVAC system probably needs attention from a professional who can make repairs or install a new unit. Look out for these common signs that your HVAC needs service:

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

Schedule an inspection if you notice any of these problems. A local technician can assess your system, identify problems, and figure out whether you need repairs or a new HVAC unit.

Cost of HVAC Installation and Maintenance in Alexandria

What you spend on HVAC installation or maintenance is determined by your system style. Common HVAC unit styles include the following:

• Split or mini-split: If your home doesn’t have the ductwork for central heating and cooling, you probably have a split or mini-split system instead. Split HVAC systems have interior units in each room to control temperature. These connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system works almost the same as a standard split system. It has the benefit of being able to utilize either electricity or gas for power.
• Heat pump: Heat pumps transfer warm and cool air between your home and outside. These systems don't produce their own heat or AC, so they work more effectively in moderate climates.
• Packaged heating and air: Packaged HVAC systems are a great choice for smaller homes. They have a single heating and cooling unit, usually in a basement or attic. This unit is often space-saving, cost-effective, and easy to maintain.

The cost of HVAC maintenance also depends on what kind of work being done. HVAC systems are complex and may require different kinds of maintenance. The prices of some common jobs are as follows:

Ways to Save Money on HVAC Costs

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

• Keep your system clean. Regularly cleaning grills, indoor evaporator coil, ductwork, and condenser fan blades helps keep your HVAC system running efficiently and reduces your risk of mold. The National Air Duct Cleaners Association advises cleaning your heating and cooling system when it starts to look dirty.
• Monitor for potential problems. Keep an eye on your system for issues, for example by routinely checking your thermostat and energy bills. This enables you to address problems before they get out of hand.
• Change filters regularly. Replacing or cleaning your air filters every 1–3 months helps air flow efficiently through your system. Also try to keep debris away from the outside areas of your HVAC system as much as possible.
• Change the position of your blinds seasonally. Leaving your blinds open during the winter allows passive solar heating to warm your home. Closing the blinds during the summer helps prevent some heat from getting inside. Doing both helps lessen the strain on your HVAC.

How To Choose a Local HVAC Company

Knowing the indicators of a good HVAC company is important. A properly licensed contractor with the right experience will give you confidence that they can fix your system, providing you with effective air conditioning and heating in 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 companies' diagnoses, suggested repairs, estimated costs, warranties, and timeframes. Avoid companies that pressure you or demand upfront payment.

Check Credentials

Choose an HVAC company with highly trained technicians who have proper licensing and experience. In all states, HVAC contractors have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, individuals must pass an exam (the type of 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 at the state level.

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. A license can 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 company's reviews and complaints with organizations such as Google Reviews, the Better Business Bureau (BBB), and Yelp. You'll want to select a company with positive reviews and a history of good customer service.

Understand Work Details

Always make sure you understand the details of any project. When HVAC repairs are required, your provider should list which parts require 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 getting a replacement, ask your contractor to explain the new HVAC system estimated installation time, model, brand, energy efficiency, and features. Before signing a contract, you should understand how your provider will size the system appropriately for your home and the price you'll pay.

Compare Warranties

Trustworthy HVAC companies provide warranties for their services. The broader the coverage, the better, so make sure to compare warranties between companies. Choose the one that gives you the most coverage at a fair cost.

Get Quote in Writing

Get a written quote before HVAC work begins. A full quote includes both labor and material costs. Make sure you understand and accept all terms before signing the contract.
