Signs You May Need HVAC Repair or Replacement

An HVAC system that's malfunctioning or old likely needs professional attention for maintenance or replacement. Watch for these signals that your system needs service:

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

If you notice any of the above, it's wise to have a local HVAC technician inspect your system. They can identify problems and let you know whether repair or full HVAC replacement is required.

Cost of HVAC Installation and Maintenance in Annandale

The price of HVAC installation or maintenance will differ depending on the kind of unit you have. Common types of HVAC units 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 internal units in each room to control temperature. These indoor units all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system performs similarly to a standard split system, but has the capacity to draw on either gas or electricity as energy sources.
  • Heat pump: Heat pumps exchange hot and cool air between your home and outside. They don't make their own heat or AC, so they function best in moderate climates.
  • Packaged heating and air: Packaged HVAC systems are a good choice for smaller homes. These systems have a single heating and cooling unit, normally located in a basement or attic. They're space-saving, cost-effective, and easy to maintain.

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

HVAC Unit TypeCost
Split$1,948-$4,966
Hybrid Split$3,947-$7,272
Heat Pump$3,056-$31,141
Packaged Heating and Air$256-$426

Ways to Save Money on HVAC Costs

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

  • Keep your system clean. Cleaning your ductwork, grills, indoor evaporator coil, and condenser fan blades regularly helps keep your HVAC system working efficiently and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system once it starts to look dirty.
  • 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.
  • Change filters regularly. Cleaning or replacing your air filters every 1–3 months 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 problems — for example, by checking your thermostat and energy bills routinely — helps you get ahead of problems before they get too expensive.
ServiceCost
Filter Replacement$64-$170
Condensor Cleaning$1,279-$3,836
Thermostat Repair$85-$213
Ductwork Cleaning$409-$1,023

How To Choose a Local HVAC Company

Knowing the indicators of a reliable HVAC company is key for a smooth installation or repair. Picking an established business with certified technicians gives you assurance your HVAC system will deliver consistent heating and cooling year-round.

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, timeframes, and warranties. Avoid providers that pressure you or demand upfront payment.

Check Credentials

When picking an HVAC provider, choose one with technicians that have the appropriate training, licenses, and experience. HVAC contractors in all states need to 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 what kind of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled by the state.

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
Reviewing feedback on the Better Business Bureau (BBB), Yelp, Google Reviews, and similar sites can aid your decision. Choose a company with great reviews and reports of positive customer experiences.

Understand Work Details

Always make sure you know the details of any project. For HVAC repairs, your provider should list which parts need replacement and why. Confirm that your technician will clean and test the full system after repairs are done to ensure that it’s working properly. When replacing your HVAC, request that the company explain the new features, brand, estimated installation time, model, and energy efficiency. Before signing a contract, be sure you understand the process your provider will use to size the new HVAC system appropriately for your home and what the price will be.

Compare Warranties

A trustworthy HVAC company will back its repair work and installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully compare warranty terms between contractors and choose the provider that offers the most protection within your budget.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Annandale, VA

You should have your HVAC system inspected approximately twice a year. At the time of the inspection, your technician will inform you what services are required. You should also call a technician if you start noticing issues such as strange noises, leaks, or unusual smells. If your system has ductwork, you should have it inspected every few years.

Normally, it's smart to have your HVAC system inspected in the spring and fall, as these times tend to be less busy. This also helps get your system ready for the summer and winter, when it likely sees the most use.

You can save energy throughout the year by reducing the amount of work it takes for your HVAC system to maintain the temperature of your home. Always keep your thermostat as close to the outside temperature as is comfortable, and try to adjust it only a few degrees at once. You may also consider getting a smart thermostat.

Generally, HVAC installation or replacement takes between one and three days for the entire system. Installing or replacing an air conditioning unit or a furnace may take anywhere from a few hours up to two days. The exact amount of time will be based on things like how large your home is, how easily accessible different sections are, and whether your technician runs into any problems.

For a 2,000-square-foot home, you'll need between 2.5 and 5 tons of air conditioning capacity. For a house over 1,000 square feet, central air will generally be more effective for cooling than window units.

For a 2,000-square-foot home, you'll also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units).

Your HVAC company might provide financing options via a third-party lender, or you might be able to obtain your own loan. It's smart to discuss payment options with a financial advisor and your HVAC company to make sure that you're choosing the best option for you.

There are several ways you can make your HVAC system more energy-efficient:

  • Keep ductwork clean, and change or clean your air filters on a regular basis.
  • Schedule regular inspections to take care of problems as they come up.
  • Make sure your doors and windows are well-sealed and keep your attic well-ventilated.
  • Install a smart thermostat. If you aren't able to purchase one, try keeping the temperature indoors as close to the outside temperature as you can.
  • When replacing part of your system, explore Energy Star-certified or similar environmentally friendly options.
