10 Best HVAC Companies in Lanham, MD

Signs You May Need HVAC Repair or Replacement

If your HVAC system is having issues or getting old, it likely needs repairs or replacement from an HVAC company. Watch for these indicators your system needs service:

• Unusually high energy bills
• Thermostat malfunctions or temperature control issues
• Uneven heating/cooling or poor air circulation
• Cracking, corrosion, or rust
• Strange noises when the system turns on
• Refrigerant leaks
• Frequent breakdowns and need for repairs
• 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 required.

Cost of HVAC Installation and Maintenance in Lanham

The cost of HVAC installation or maintenance will differ depending on the kind of unit you have. Common varieties of HVAC units include the following:

• Split or mini-split: Homes without ductwork for central heating and cooling frequently have split or mini-split HVAC systems. These systems consist of internal units in each room to control temperature. These indoor units connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions comparably to a regular split system. It gives 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 generate their own heat or AC, so they function best in mild climates.
• Packaged heating and air: Packaged HVAC systems work well in smaller houses. They consist of a single combined heating and air conditioning unit, commonly located in an attic or basement. This unit is typically small, cost-effective, and easy to maintain.

HVAC maintenance prices vary depending on the particular service needed. HVAC systems are complicated and might require different maintenance services. Costs for common services are as follows:

Ways to Save Money on HVAC Costs

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

• Keep your system clean. Regularly cleaning indoor evaporator coil, condenser fan blades, ductwork, and grills helps keep your HVAC system running efficiently and reduces your risk of mold. The National Air Duct Cleaners Association advises cleaning your heating and cooling system when it starts to look dirty.
• Change the position of your blinds seasonally. Opening your blinds in winter allows passive solar heat into your house. Closing your blinds in summer blocks some heat from getting indoors. Both of these measures help decrease the work required from your HVAC system.
• Change filters regularly. Switching out or cleaning your air filters every 1–3 months helps air flow smoothly 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 regularly — helps you catch issues before they get too expensive.

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 fix your system, providing you with effective heating and cooling for your home.

Compare Multiple Bids

Get quotes from three or more HVAC providers. Explain your issues and ask if technicians can inspect your system in person. Compare each provider's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid companies that pressure you or demand payment before work.

Check Credentials

Look for an HVAC company that employs qualified technicians who have the necessary licensure and training. HVAC contractors in all states need to 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 the type 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.

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 show proof of both general liability and property damage insurance. Checking reviews on Google Reviews, Yelp, the Better Business Bureau (BBB), and similar sites can assist your decision. Choose a company with stellar reviews and stories of positive customer experiences.

Understand Work Details

Make sure you know the details of any project before it begins. For HVAC repairs, have your provider specify which parts require replacement and why. Get confirmation that your technician will clean and test your system after the repair to ensure that everything works. For replacement, ask your contractor to explain the new HVAC system energy efficiency, estimated installation time, features, brand, and model. Before work begins, you should understand how your provider will size the system appropriately for your home and the price you'll pay.

Compare Warranties

Good HVAC companies offer warranties on repairs and installations. The more complete the coverage, the better. Review warranty details between companies and pick the one that offers the most comprehensive protection for the fairest price.

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.
