10 Best HVAC Companies in Lexington Park, MD

Signs You May Need HVAC Repair or Replacement

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

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

Schedule an inspection if you notice any of these problems. A local technician can inspect your system, identify problems, and determine whether you need to fix or replace your HVAC.

Cost of HVAC Installation and Maintenance in Lexington Park

Your HVAC installation or maintenance cost changes depending on the style of unit. Common HVAC unit types include the following:

• Split or mini-split: If your home doesn’t have the ductwork for central air or heating, you probably have a split or mini-split system instead. Split HVAC systems have interior units in each room to control temperature. These connect 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 being able to utilize either gas or electricity for power.
• Heat pump: Heat pumps exchange warm and cool air between your home and the outside. These systems don't make their own heat or AC, so they work better in more temperate climates.
• Packaged heating and air: Packaged HVAC systems are often a good option for smaller homes. These systems consist of a single combined heating and cooling unit that's usually located in a basement or attic. This unit tends to be compact, efficient, and easy to maintain.

The amount you spend on HVAC maintenance also depends on the kind of work you're having done. HVAC systems are complicated and may require different kinds of maintenance. The cost of some common repairs is as follows:

Ways to Save Money on HVAC Costs

It's important to fix or swap out your HVAC components when they become damaged, but it can also be expensive. Fortunately, there are some 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.
• Keep your system clean. Keeping your ductwork, grills, indoor evaporator coil, and condenser fan blades clean helps your system function optimally and reduces the chance 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. Leaving your blinds open during the colder months helps warm your home with passive solar heating. Closing the blinds during the summer helps prevent some heat from getting inside. Doing both helps lessen the demand on your HVAC.
• Change filters regularly. Replacing your air filters or washing them every 30–90 days allows smooth air circulation through your system. Also try to keep debris from accumulating on the outdoor sections of your HVAC.

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 providers for quotes. Describe 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

Choose an HVAC company with skilled technicians who have proper licensing and experience. HVAC contractors in all states have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, individuals must pass an exam (the specific exam depends on the 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 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 is required to have at least three years of experience and must have both property damage and general liability insurance. Also check a company's reviews and complaints on sites such as Google Reviews, the Better Business Bureau (BBB), and Yelp. Pick a company with great feedback and good customer testimonials.

Understand Work Details

Make sure you know the details of your project before starting. When getting 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, ask the provider to explain the new energy efficiency, features, model, brand, and estimated installation time. Before signing paperwork, be sure you understand the process your provider will use to size the new HVAC system appropriately for your home and what the price will be.

Compare Warranties

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

Get Quote in Writing

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