10 Best HVAC Companies in Rockville, MD

Signs You May Need HVAC Repair or Replacement

If your HVAC system is broken or getting near the end of its lifespan, it likely needs servicing or replacement from an HVAC company. Look for these signs your system needs service:

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

If you notice any of these HVAC red flags, your system evaluated. A local provider can complete an inspection, diagnose problems, and advise you whether you should repair or replace your HVAC unit.

Cost of HVAC Installation and Maintenance in Rockville

The price of HVAC installation or maintenance will vary depending on the kind of unit you have. Common types of HVAC units include the following:

• Split or mini-split: If your home lacks the ductwork for central air or heating, 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 unit operates similarly to a regular split system. It provides flexibility by providing the option to use either electricity or gas for energy.
• Heat pump: Heat pumps move hot and cold air between your house and the outdoors. They don't create their own heating and cooling, so they work best in more temperate climates.
• Packaged heating and air: Packaged HVAC systems are more popular in smaller homes. Packaged systems consist of a single heating and cooling unit, usually located in an attic or basement. This unit tends to be compact, efficient, and easy to maintain.

HVAC maintenance costs differ based on the specific services needed. HVAC systems can be complex and potentially require a number of services. Fees for typical jobs are as follows:

Ways to Save Money on HVAC Costs

Repairing or replacing your HVAC system when needed is crucial, but can be costly. Fortunately, there are steps you can take to minimize wear and tear over time on your system.

• Change the position of your blinds seasonally. Leaving your blinds open during the colder months allows passive solar heating to warm your home. Closing the blinds in warmer seasons helps prevent the heat from getting inside. Doing both helps minimize the demand on your HVAC system.
• Keep your system clean. Keeping your indoor evaporator coil, condenser fan blades, ductwork, and grills clean helps your HVAC system function properly and lowers the risk of mold. The National Air Duct Cleaners Association recommends cleaning your home's HVAC when you notice things starting to get dirty.
• 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 outdoor portions of your HVAC system as much as possible.
• Monitor for potential problems. Keeping an eye out for problems, for instance by consistently checking your thermostat and energy bills, allows you to resolve them before they get too expensive.

How To Choose a Local HVAC Company

Knowing the indicators of a reliable HVAC company is key for a smooth repair or installation. 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 companies for quotes. Explain the issues and have technicians visit to inspect your HVAC system if possible. Compare the companies' explanations, solutions, estimated costs, timeframes, and warranties. Avoid companies that pressure you or demand payment upfront.

Check Credentials

Look for an HVAC company that employs qualified technicians who have the necessary licensure and training. In all states, HVAC contractors must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required 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 on a state-by-state basis.

HVAC contractors in Maryland are licensed by the Maryland Board of Heating, Ventilation, Air Conditioning and Refrigeration Contractors. To obtain a master or master restricted license, a contractor must have at least three years of experience and must have both general liability and property damage insurance. You should also check a provider's reviews and complaints with organizations such as Google Reviews, the Better Business Bureau (BBB), and Yelp. You want to hire a company with positive reviews and a history of good customer service.

Understand Work Details

Always make sure you understand the details of your project. For HVAC repairs, your provider should list which parts require 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 system, ask the contractor to describe the new energy efficiency, estimated installation time, model, features, and brand. 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

Good HVAC companies offer warranties on repairs and installations. The more complete the coverage, the better. Compare warranty details between companies and pick the one that provides the best protection for a fair price.

Get Quote in Writing

Get written quotes before beginning any HVAC work. The quote should cover costs for both labor and materials. Review all terms carefully before signing.
