Signs You May Need HVAC Repair or Replacement

A malfunctioning or aging HVAC system probably needs attention from a professional who can make fixes or install a new unit. Keep an eye out for these common signs that your HVAC needs service:

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

Book an inspection if you notice any of these issues. A local technician can evaluate your system, detect problems, and decide whether you need to fix or replace your HVAC.

Cost of HVAC Installation and Maintenance in Chantilly

Your HVAC installation or maintenance cost fluctuates depending on the type of unit. Common HVAC unit varieties include the following:

• Split or mini-split: If your home's ductwork can't accommodate a central HVAC system, you probably have a split or mini-split system. Split systems have interior units in each room to regulate 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 for power.
• Heat pump: Heat pumps work by circulating warm and cool air between your home and the outdoors. These systems don't generate heat or air conditioning themselves, and are more suited to more moderate climates.
• Packaged heating and air: Packaged HVAC systems work best in smaller homes. They consist of a single combined air conditioner and heating unit, commonly located in an attic or basement. This unit is typically small, energy-efficient, and straightforward to maintain.

The price of HVAC maintenance also varies depending on the kind of work being done. HVAC systems are complicated and can require different kinds of maintenance. The prices of some common jobs are as follows:

Ways to Save Money on HVAC Costs

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

• 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.
• Change filters regularly. Cleaning or replacing your air filters every 1–3 months helps air flow smoothly through your system. Also try to keep debris away from the outdoor portions of your HVAC system as much as possible.
• Keep your system clean. Regularly cleaning condenser fan blades, indoor evaporator coil, grills, and ductwork helps your HVAC system run efficiently and lowers your risk of mold. The National Air Duct Cleaners Association advises cleaning your system when it starts to look dirty.
• Change the position of your blinds seasonally. Closing your blinds in the summer blocks some passive solar heat from getting indoors. Opening the blinds in the winter allows this same heat to help warm your home. Both of these measures help decrease the work required from your house's HVAC system.

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 heating and air conditioning for your home.

Compare Multiple Bids

Contact at least three HVAC companies for quotes. Explain the issues and have technicians visit to inspect your system if possible. Compare the providers' explanations, solutions, estimated costs, warranties, and timeframes. Avoid providers that pressure you or demand payment upfront.

Check Credentials

Look for an HVAC company that employs qualified technicians with the necessary licensure and training. In all states, HVAC contractors need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for all contractors who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." An individual 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 at the state level.

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 both education and experience 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

Also check a company's reviews and complaints on sites such as Yelp, Google Reviews, and the Better Business Bureau (BBB). Pick a company with positive feedback and good customer testimonials.

Understand Work Details

It’s important to understand what the work process will look like. For HVAC repairs, the company should list the exact parts that need replacement and why. Get confirmation that your technician will clean and test the full system afterward to ensure proper functioning. When replacing your HVAC system, have the provider describe the new brand, features, energy efficiency, estimated installation time, and model. Before signing a contract, ask about the process your provider will use to properly size the new system for your home and how much it will cost.

Compare Warranties

Reliable HVAC companies offer warranties on repairs and installations. The more complete the coverage, the better. Compare warranty details between providers and pick the one that offers the most comprehensive protection within your budget.

Get Quote in Writing

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