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. Keep an eye out for these common indicators that your HVAC needs service:

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

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

Cost of HVAC Installation and Maintenance in Chevy Chase

What you pay for HVAC installation or maintenance depends on your system style. Common HVAC unit styles include the following:

• Split or mini-split: Homes without ductwork for central air often have split or mini-split HVAC systems. These systems consist of interior units in each room to regulate temperature, which all connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system operates similar to a normal split system, but has the advantage of being able to draw power from either electric or gas sources.
• Heat pump: Heat pumps work by transferring warm and cool air between your home and the outdoors. These systems don't create heat or air conditioning themselves, and are better for more moderate climates.
• Packaged heating and air: Packaged HVAC systems are a good choice for smaller homes. These systems have a single combined AC and heating, normally located in a basement or attic. They're space-saving, cost-effective, and easy to maintain.

The amount you spend on HVAC maintenance also varies depending on what kind of work you're having done. HVAC systems are complex and might require different kinds of maintenance. The cost of some common repairs is as follows:

Ways to Save Money on HVAC Costs

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

• 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 strain on your HVAC system.
• Change filters regularly. Air flows best through your HVAC system when you replace or clean the filters every 30–90 days. Also avoid letting debris pile up on the outdoor parts of your HVAC.
• Monitor for potential problems. Keeping an eye out for problems, for instance by routinely checking your thermostat and energy bills, allows you to resolve them before they get out of hand.
• Keep your system clean. Keeping your condenser fan blades, indoor evaporator coil, grills, and ductwork clean helps your HVAC system function properly and lowers your risk of mold. The National Air Duct Cleaners Association suggests cleaning your home's HVAC system when you notice it starting to get dirty.

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 maintain your HVAC system properly, providing you with effective heating and cooling for your home.

Compare Multiple Bids

Contact at least three HVAC companies for quotes. Explain 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 well-trained technicians who have proper licensing and experience. HVAC contractors in all states 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 what kind of equipment they intend 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 by the state.

In Maryland, HVAC contractors are licensed by the Maryland Board of Heating, Ventilation, Air Conditioning and Refrigeration Contractors. To obtain a master or master restricted license, a contractor needs to have at least three years of experience and must hold both property damage and general liability insurance. You should also look at a company's reviews and complaints on sites such as the Better Business Bureau (BBB), Yelp, and Google Reviews. 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 explain the exact parts that need replacement and why. Get confirmation that your technician will clean and test your system afterward to ensure proper functioning. When replacing your HVAC, ask the provider to explain the new model, features, estimated installation time, brand, and energy efficiency. Before work starts, make sure you understand how your provider will determine the right system size for your home and what the price will be.

Compare Warranties

A trustworthy HVAC company will back its repair services and equipment installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully review the fine print for each contractor and choose the company that provides the greatest protection at a reasonable price.

Get Quote in Writing

Always get estimates for HVAC service in writing before committing to a provider. A detailed quote should cover both labor and materials. Make sure you agree to all terms before signing a contract.
