10 Best HVAC Companies in Greenbelt, MD

Signs You May Need HVAC Repair or Replacement

If your home's HVAC system is malfunctioning or suffering from a lot of wear and tear, you may need to hire an HVAC contractor for repairs or replacement. Look for these common signs that your system needs expert attention:

• Unusually high energy bills
• Temperature control issues or thermostat malfunctions
• Poor air circulation or uneven heating/cooling
• Frequent breakdowns and need for repairs
• Strange noises when the system turns on
• Corrosion, cracking, or rust
• Refrigerant leaks
• An HVAC system that's over 15 years old

These HVAC red flags indicate that you should have your system evaluated. A local provider can complete an inspection, diagnose problems, and recommend repairing or replacing your HVAC unit.

Cost of HVAC Installation and Maintenance in Greenbelt

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

• Split or mini-split: If your home lacks the right ductwork for central air or heating, you likely have a split HVAC system. Split or mini-split systems consist of indoor units that control the temperature in individual rooms, and that are all connected to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions in the same way as a normal split system, but has the benefit of being able to utilize energy from either gas or electric sources.
• Heat pump: Heat pumps exchange hot and cold air between your house and outside. They don't make their own heating and cooling, so they work more effectively in more mild climates.
• Packaged heating and air: Packaged HVAC systems are a smart choice for smaller homes. They have a single cooling and heating unit, typically in an attic or basement. This unit is often space-saving, cost-effective, and easy to maintain.

HVAC maintenance costs differ depending on the particular service needed. HVAC systems are complicated and may require different maintenance services. Costs for common services are as follows:

Ways to Save Money on HVAC Costs

It's important to take care of HVAC repairs and replacements in a timely manner, but it can also be expensive. Luckily, there are steps you can take to reduce wear and tear on your HVAC.

• 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 out of hand.
• Change filters regularly. Replacing or cleaning your air filters every 30–90 days helps air flow smoothly through your HVAC system. You should also try to prevent dirt and debris from building up around the outdoor sections of your system.
• Keep your system clean. Cleaning your indoor evaporator coil, ductwork, condenser fan blades, and grills regularly helps your HVAC system work efficiently and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC 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 lower the work required from your HVAC system.

How To Choose a Local HVAC Company

Knowing what makes a trustworthy HVAC company is crucial for a smooth installation or repair. Hiring an experienced, credentialed HVAC contractor gives you confidence your system can provide consistent heating and air conditioning year-round.

Compare Multiple Bids

Contact at least three HVAC contractors for quotes. Describe your issues and schedule an in-person inspection if possible. Compare companies' diagnoses, suggested repairs, estimated costs, timeframes, and warranties. Avoid providers that pressure you or demand upfront payment.

Check Credentials

Look for an HVAC company that employs skilled 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 mandatory for any individual who helps "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 the type of equipment they intend to work with) to be certified by the EPA. 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 is required to have at least three years of experience and must show proof of both property damage and general liability insurance. You should also check a provider's reviews and complaints with organizations such as Yelp, the Better Business Bureau (BBB), and Google Reviews. Choose a provider with positive reviews and a history of good customer service.

Understand Work Details

Make sure you know the details of any project before starting. For HVAC repairs, have your provider list which parts need replacement and why. Confirm that your technician will clean and test the system after the repair to ensure that everything works. When replacing your HVAC system, ask the installation company to provide details on the new estimated installation time, brand, energy efficiency, features, and model. Before signing a contract, make sure you understand the process your provider will use to select the correctly sized system for your home and what the cost will be.

Compare Warranties

A reputable HVAC company will back its repair work and 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 most protection within your budget.

Get Quote in Writing

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