Signs You May Need HVAC Repair or Replacement

If your HVAC system is faulty or getting near the end of its lifespan, it likely needs servicing or replacement from an HVAC company. Watch for these signs your system needs service:

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

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

Cost of HVAC Installation and Maintenance in Baltimore

What you spend on HVAC installation or maintenance is determined by your system style. Common HVAC unit styles include the following:

• Split or mini-split: Homes without ductwork for centralized climate control often have split or mini-split HVAC systems. These systems consist of internal units in each room to control temperature, which all connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC unit operates similarly 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 exchange warm and cool air between your home and outside. These systems don't generate their own heat or AC, so they work better in 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 that's usually located in a basement or attic. This unit tends to be efficient, compact, and easy to maintain.

The cost of HVAC maintenance also varies depending on the kind of work being done. HVAC systems are complicated and might 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 complete repairs or full-system HVAC replacements as needed, though they can be expensive. The good news is that homeowners have methods to decrease the effect of wear and tear and reduce the frequency of breakdowns.

• Keep your system clean. Cleaning your condenser fan blades, grills, ductwork, and indoor evaporator coil regularly helps your HVAC system work efficiently and lowers the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it begins to look dirty.
• 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 the heat from getting inside. Doing both helps decrease the demand on your HVAC.
• Monitor for potential problems. Monitoring your system for issues — for example, by checking your thermostat and energy bills regularly — helps you catch issues before they get too expensive.
• Change filters regularly. Cleaning or replacing your air filters every 30–90 days helps air flow efficiently through your system. You should also try to keep debris away from the external sections of your HVAC system as much as possible.

How To Choose a Local HVAC Company

Knowing the indicators of a reliable HVAC company is key for a smooth installation or repair. Picking an established business with certified technicians gives you assurance your HVAC system will deliver consistent heating and cooling year-round.

Compare Multiple Bids

Request estimates from at least three HVAC companies. Describe your issues and ask if technicians can inspect your system in person. Review each contractor's diagnoses, recommended solutions, estimated cost, timelines, and warranties. Avoid contractors that pressure you or demand payment before work.

Check Credentials

When selecting an HVAC company, choose one with technicians that have the right 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 technicians 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 the type 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 is required to have at least three years of experience and must have both general liability and property damage insurance. Reviewing feedback on the Better Business Bureau (BBB), Google Reviews, Yelp, and similar sites can help your decision. Choose a company with stellar reviews and reports of positive customer experiences.

Understand Work Details

Make sure you know the details of your project before starting. For HVAC repairs, have your provider list which parts need replacement and why. Get confirmation that your technician will clean and test your system after the repair to verify that everything works. When replacing your HVAC, ask the contractor to describe the new estimated installation time, brand, energy efficiency, model, and features. Before signing a contract, ask how your provider plans to accurately size the unit for your home and how much it will cost.

Compare Warranties

Trustworthy HVAC companies provide warranties for their services. Broader coverage is 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 estimates before starting HVAC work. The quote should outline costs for both materials and labor. Read all terms carefully before signing.
