Signs You May Need HVAC Repair or Replacement

If your home's HVAC system isn't working correctly or nearing the end of its lifespan, you might need an HVAC contractor for repairs or replacement. Watch for these common signs that your system needs expert attention:

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

Cost of HVAC Installation and Maintenance in Fair Oaks

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

  • Split or mini-split: Homes without ductwork for centralized climate control often have split or mini-split HVAC systems. These systems consist of indoor units in each room to control temperature, which all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions comparably to a regular split system. It provides flexibility by providing the option to use either electricity or gas for energy.
  • Heat pump: Heat pumps circulate warm and cold air between your home and outside. They don't make their own heat or AC, so they work best in mild climates.
  • Packaged heating and air: Packaged HVAC systems are a good choice for smaller homes. These systems have a single heating and cooling unit, typically located in a basement or attic. They're small, cost-effective, and easy to maintain.

HVAC maintenance prices differ 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:

HVAC Unit TypeCost
Split$1,891-$4,820
Hybrid Split$3,831-$7,058
Heat Pump$2,966-$30,226
Packaged Heating and Air$248-$414

Ways to Save Money on HVAC Costs

It's important to repair or replace your HVAC system when it's broken, but it can also be expensive. Thankfully, there are steps you can take to reduce wear and tear on your system.

  • Change filters regularly. Changing or cleaning your air filters every 30–90 days helps air flow efficiently through your HVAC system. You should also try to prevent dirt and debris from building up around the outside areas of your system.
  • Monitor for potential problems. Monitoring your system for problems — for example, by checking your thermostat and energy bills routinely — helps you catch issues before they get too expensive.
  • Change the position of your blinds seasonally. Keeping your blinds closed in the summer helps block out passive solar heat. Keeping them open in the winter helps you take advantage of this same heat. Both of these measures help reduce the amount of work your HVAC system needs to do.
  • Keep your system clean. Keeping your ductwork, grills, indoor evaporator coil, and condenser fan blades clean enables your HVAC system to function properly and lowers the risk of mold. The National Air Duct Cleaners Association suggests cleaning your HVAC system when you notice things starting to get dirty.
ServiceCost
Filter Replacement$62-$165
Condensor Cleaning$1,241-$3,723
Thermostat Repair$83-$207
Ductwork Cleaning$397-$993

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is important for a successful project. Look for an experienced, licensed contractor that can offer you peace of mind and make sure your system provides reliable air conditioning and heating for your home.

Compare Multiple Bids

Get quotes from at least three HVAC contractors. Describe your issues and ask if specialists can inspect your system in person. Review each company's diagnoses, recommended solutions, estimated cost, warranties, and timelines. Avoid contractors that pressure you or demand payment before work.

Check Credentials

Choose an HVAC company with skilled technicians who have appropriate 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 specific exam depends on what 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 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. 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 provider's reviews and complaints with organizations such as Google Reviews, Yelp, and the Better Business Bureau (BBB). You'll want to select a provider with glowing reviews and stories of positive service experiences.

Understand Work Details

It’s important to understand what the work process is going to look like. For HVAC repairs, the company should explain the exact parts that need replacement and why. Get confirmation that your technician will clean and test your system afterward to make sure everything is operating properly. When replacing your HVAC, ask the provider to explain the new energy efficiency, features, estimated installation time, model, and brand. 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

Trustworthy HVAC companies provide warranties for their work. Broader coverage is better, so make sure to compare warranties between companies. Choose the one that provides the most comprehensive coverage at a reasonable cost.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Fair Oaks, VA

You should have your HVAC system inspected about twice annually. Following an inspection, your technician will inform you if any services are needed. You should also have your system inspected if you notice new issues such as unusual smells, strange noises, or leaks. If your system has ductwork, you should have it inspected every few years.

Normally, you should have your HVAC system inspected in the spring and fall, as technicians tend to be less busy at these times. This also helps make sure your system is prepared for the summer and winter, when it likely sees the most use.

You can save energy throughout the year by making it easier for your HVAC system to maintain your home's temperature. Always keep your thermostat as close to the outside temperature as possible, and avoid making drastic changes — adjust it only a few degrees at a time. You might also consider getting a smart thermostat.

Generally, HVAC installation or replacement takes between one and three days for the entire system. Installing or replacing a furnace or air conditioning unit may take anywhere from a few hours up to two days. The exact amount of time will vary depending on things like the size of your house, how easily accessible different areas are, and whether your technician finds any problems.

For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. If your home is larger than 1,000 square feet, central air will generally be more effective than window units for cooling.

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

Usually, HVAC financing is offered through a third-party lender. If your HVAC company doesn't offer these options, you might consider taking out a loan on your own. Be sure to talk to a financial advisor and your HVAC company to determine what options are available and appropriate for your situation.

There are a number of ways you can make your HVAC system more energy-efficient:

  • Make sure your air ducts remain clean, and clean or change your air filters on a regular basis.
  • Schedule regular inspections to take care of problems as they arise.
  • 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 is comfortable.
  • When you need to replace part of your system, see if there are Energy Star-certified or similar environmentally friendly options.
