10 Best HVAC Companies in Largo, MD

Signs You May Need HVAC Repair or Replacement

A malfunctioning or aging HVAC system probably needs professional attention from a technician who can make fixes or install a new unit. Keep an eye out for these common indicators that your HVAC needs service:

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

If you notice any of these HVAC issues, we recommend having a technician inspect your system. A local professional can diagnose problems and determine whether fixing or replacing your HVAC unit is the correct solution.

Cost of HVAC Installation and Maintenance in Largo

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

• Split or mini-split: Homes without ductwork for centralized climate control 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 provides flexibility by having the option to draw on either electricity or gas for energy.
• Heat pump: Heat pumps move warm and cool air between your home and outside. These systems don't generate their own heat or AC, so they work more effectively in more temperate climates.
• Packaged heating and air: Packaged HVAC systems are a good choice for smaller houses. These systems have a single heating and cooling unit, normally located in a basement or attic. They're space-saving, energy-efficient, and easy to maintain.

HVAC expenses vary based on the services needed. HVAC systems are complicated and may need several types of maintenance. Prices for common jobs are as follows:

Ways to Save Money on HVAC Costs

HVAC system repairs and replacements are important, but can be pricey. Thankfully, there are steps homeowners can take to reduce wear and tear on their system and lower future maintenance needs.

• 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 some heat from getting inside. Doing both helps reduce the demand on your HVAC system.
• Keep your system clean. Regularly cleaning ductwork, indoor evaporator coil, condenser fan blades, and grills helps your HVAC system run efficiently and reduces the risk of mold. The National Air Duct Cleaners Association advises cleaning your system when it starts to look dirty.
• Change filters regularly. Cleaning or replacing your air filters every 30–90 days helps air flow smoothly through your system. You should also try to keep debris away from the external sections 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, helps you resolve them before they get too expensive.

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is crucial 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

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

Check Credentials

When hiring an HVAC company, choose one with technicians that have the right training, licenses, and experience. HVAC contractors in all states 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." An individual 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 show proof of both property damage and general liability insurance. You should also look at reviews and complaints on sites like the Better Business Bureau (BBB), Yelp, and Google Reviews. Choose a company with positive reviews and testimonials about good customer experiences.

Understand Work Details

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

Compare Warranties

Reliable HVAC companies provide warranties for their services. The broader the coverage, the better, so make sure to review warranties between companies. Choose the one that gives you the most coverage at a reasonable cost.

Get Quote in Writing

Always get quotes for HVAC service in writing before committing to a provider. A comprehensive quote should cover both labor and materials. Make sure you agree to all terms before signing a contract.
