10 Best HVAC Companies in Severn, MD

Signs You May Need HVAC Repair or Replacement

A faulty or aging HVAC system probably needs attention from a professional who can make fixes or install a new unit. Watch out for these common signs that your HVAC needs service:

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

Arrange an inspection if you notice any of these problems. A local technician can inspect your system, detect problems, and decide whether you need repairs or a new HVAC unit.

Cost of HVAC Installation and Maintenance in Severn

Your HVAC installation or maintenance cost fluctuates depending on the type of unit. Common HVAC unit varieties 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 indoor units in each room to regulate temperature, which all connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions comparably to a regular split system. It provides flexibility by providing the option to draw on either electricity or gas for energy.
• Heat pump: Heat pumps exchange hot and cold air between your home and outside. They don't generate their own heating and cooling, so they work best in more moderate climates.
• Packaged heating and air: Packaged HVAC systems are a great choice for smaller homes. They have a single cooling and heating unit, usually in an attic or basement. This unit is often space-saving, energy-efficient, and easy to maintain.

HVAC maintenance costs differ depending on the particular service needed. HVAC systems are complex and might require different kinds of maintenance. Costs for some 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. Luckily, there are actions you can take to minimize wear and tear over time on your system.

• Keep your system clean. Keeping your grills, ductwork, condenser fan blades, and indoor evaporator coil clean enables your HVAC system to 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.
• Monitor for potential problems. Monitor your system for issues, for example by routinely checking your thermostat and energy bills. This helps you address issues before they get out of hand.
• Change filters regularly. Air flows best through your HVAC system when you replace or clean the filters every 1–3 months. Also try not to let debris pile up on the outdoor parts of your HVAC.
• Change the position of your blinds seasonally. Leaving your blinds open during the winter allows passive solar heating to warm your home. Closing the blinds during the summer helps prevent the same heat from getting inside. Doing both helps minimize the demand on your HVAC.

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is important for a successful project. Look for an experienced, licensed contractor that can give you peace of mind and ensure your system provides reliable air conditioning and heating for your home.

Compare Multiple Bids

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

Check Credentials

It's important to choose an HVAC company that employs technicians with the proper qualifications and expertise. HVAC contractors in all states have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, a contractor must pass an exam (the type of exam depends on what kind of equipment they plan 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 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 must have at least three years of experience and must show proof of both general liability and property damage insurance. Reviewing feedback on the Better Business Bureau (BBB), Yelp, Google Reviews, and similar sites can help your decision. Choose a provider with stellar reviews and reports of positive experiences from customers.

Understand Work Details

Make sure you know the details of your project before starting. If HVAC repairs are required, have your provider list which parts need replacement and why. Confirm that your technician will clean and test the entire system after the repair to verify that everything works. When replacing your HVAC, have the provider describe the new brand, model, features, estimated installation time, and energy efficiency. Before work starts, 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

Reputable HVAC companies stand behind their work with warranties. Look at warranties from different companies, bearing in mind that broader coverage is better. Look for the provider that offers the most coverage for a reasonable price.

Get Quote in Writing

Always get HVAC quotes in writing before work begins. A detailed quote covers costs for both labor and materials. Confirm that you understand all terms before signing the contract.
