10 Best HVAC Companies in Calverton, MD

Signs You May Need HVAC Repair or Replacement

An HVAC system that's malfunctioning or outdated likely needs professional attention for maintenance or replacement. Watch for these signs that your system needs service:

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

Arrange an inspection if you notice any of these problems. A local technician can assess your system, identify problems, and figure out whether you need to fix or replace your HVAC.

Cost of HVAC Installation and Maintenance in Calverton

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

• Split or mini-split: If your home doesn't have the right ductwork for central air or heating, you likely have a split HVAC system. Split or mini-split systems consist of interior units that control the temperature in individual rooms. These interior units are all connected to an outdoor unit.
• Hybrid split: A hybrid split HVAC system works almost the same as a standard split system. It has the benefit of having the capability to use either electricity or gas for power.
• Heat pump: Heat pumps work by moving hot and cold air between your home and the outdoors. These systems don't generate heat or air conditioning themselves, and are more effective in more moderate climates.
• Packaged heating and air: Packaged HVAC systems are good for smaller homes. Packaged systems consist of a single combined heating and cooling unit, normally located in a basement or attic. This unit tends to be compact, efficient, and easy to maintain.

HVAC maintenance costs differ depending on the particular service needed. HVAC systems are complex and might require different maintenance services. Costs for some 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 system.

• Change filters regularly. Replacing or cleaning your air filters every 1–3 months helps air flow smoothly through your HVAC system. We also recommend regularly clearing dirt and debris away from the outside areas of your system.
• Keep your system clean. Cleaning your condenser fan blades, ductwork, grills, and indoor evaporator coil regularly helps keep your HVAC system working efficiently and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system once it begins to look dirty.
• Monitor for potential problems. Keep an eye on your system for issues, for example by routinely checking your thermostat and energy bills. This helps you address problems before they get out of hand.
• Change the position of your blinds seasonally. During winter, leave your blinds open so your home benefits from passive solar heat. In summer, keep blinds shut to block out heat. Doing both reduces the amount of work your HVAC system must perform.

How To Choose a Local HVAC Company

Knowing the indicators of a good HVAC company is important. Working with a contractor that's properly licensed and highly experienced will give you confidence that they can keep your system running efficiently, providing you with effective heating and cooling in 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 contractors' explanations, solutions, estimated costs, timeframes, and warranties. Avoid companies that pressure you or demand payment upfront.

Check Credentials

When looking for an HVAC provider, choose one with technicians that have the appropriate training, licenses, and experience. In all states, HVAC contractors must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for all contractors 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 at the state level.

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 needs to have at least three years of experience and must have both general liability and property damage insurance. You should also check reviews and complaints on sites like Yelp, the Better Business Bureau (BBB), and Google Reviews. Pick a company with positive reviews and testimonials about good customer experiences.

Understand Work Details

Always make sure you know the details of any project. For HVAC repairs, your provider should list which parts need replacement and why. Confirm that your technician will clean and test the full system after repairs are completed to verify that it’s working properly. When replacing your HVAC system, ask the contractor to describe the new features, estimated installation time, brand, energy efficiency, and model. Before work starts, ask how your provider plans to accurately size the unit for your home and how much it will cost.

Compare Warranties

Reliable HVAC companies provide warranties for their work. The broader the coverage, the better, so make sure to review warranties between providers. Choose the one that offers the best coverage at a reasonable cost.

Get Quote in Writing

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