10 Best HVAC Companies in Annapolis, MD

Signs You May Need HVAC Repair or Replacement

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

• Temperature control issues or thermostat malfunctions
• Uneven heating/cooling or poor air circulation
• Odd noises when turning on
• Rust, corrosion, or cracking
• Unusually high energy bills
• Refrigerant leaks
• Frequent breakdowns and need for repairs
• An HVAC system that's over 15 years old

Book 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 Annapolis

The price 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: If your home's ductwork can't accommodate a central HVAC system, you probably have a split or mini-split system. Split systems have indoor units in each room to regulate temperature; these indoor units all connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system works almost the same as a standard split system. It has the advantage of having the capability to use either gas or electricity for power.
• Heat pump: Heat pumps circulate warm and cold air between your home and the outdoors. They don't generate their own heat or AC, so they work best in temperate climates.
• Packaged heating and air: Packaged HVAC systems are a smart choice for smaller homes. These systems have a single heating and cooling unit, typically located in a basement or attic. They're small, cost-effective, and easy to maintain.

HVAC maintenance prices differ based on the specific services needed. HVAC systems can be complicated and potentially require a number of services. Costs for typical jobs are 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. Luckily, there are steps you can take to reduce wear and tear on your HVAC.

• Monitor for potential problems. Monitor your system for issues, for example by consistently checking your thermostat and energy bills. This allows you to address problems before they get too expensive.
• Change filters regularly. Changing or cleaning your air filters every 30–90 days helps air flow efficiently through your HVAC system. You should also try to prevent dirt and debris from building up around the outside areas of your system.
• Change the position of your blinds seasonally. Closing your blinds in the summer blocks some passive solar heat from getting indoors. Opening the blinds in the winter allows this same heat to help warm your home. Both of these measures help decrease the work required from your house's HVAC system.
• Keep your system clean. Keeping your condenser fan blades, indoor evaporator coil, grills, and ductwork clean helps your system run and reduces the chance of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.

How To Choose a Local HVAC Company

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

Compare Multiple Bids

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

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 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 by the state.

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 property damage and general liability insurance. You should also check reviews and complaints on sites like the Better Business Bureau (BBB), Google Reviews, and Yelp. Choose a company with positive reviews and testimonials about fantastic customer experiences.

Understand Work Details

It’s important to understand what the work process is going to look like. For HVAC repairs, the company should detail the exact parts that need replacement and why. Get confirmation that your technician will clean and test the full system afterward to ensure proper functioning. When replacing your HVAC, ask the contractor to describe the new features, brand, energy efficiency, estimated installation time, 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

Trustworthy HVAC companies stand behind their services with warranties. Look at warranties from different companies, bearing in mind that more comprehensive coverage is better. Look for the company that offers the most coverage for a reasonable price.

Get Quote in Writing

Get a written quote before HVAC work begins. A comprehensive quote includes both labor and material costs. Make sure you understand and accept all terms before signing the contract.
