Signs You May Need HVAC Repair or Replacement

An HVAC system that's not working properly or old likely needs professional attention for maintenance or replacement. Watch for these indicators that your system needs service:

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

If you notice any of the above, it's wise to have a local HVAC technician inspect your system. They can pinpoint problems and determine whether repair or full HVAC replacement is the best course of action.

Cost of HVAC Installation and Maintenance in Dundalk

What you pay for HVAC installation or maintenance varies based on your system style. Common HVAC unit styles include the following:

• Split or mini-split: If your home doesn’t have the ductwork for central air or heating, you likely have a split or mini-split system instead. Split HVAC systems have internal units in each room to control temperature. These connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions in the same way as a normal split system, but has the benefit of being able to utilize energy from either gas or electric sources.
• Heat pump: Heat pumps transfer hot and cool air between your home and the outdoors. They don't produce their own heat or AC, so they perform best in mild climates.
• Packaged heating and air: Packaged HVAC systems work best in smaller houses. They consist of a single combined heating and air conditioning unit, commonly located in an attic or basement. This unit is typically space-saving, cost-effective, and easy to maintain.

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

Ways to Save Money on HVAC Costs

Taking care of necessary HVAC repairs and replacements when needed is important, but can be expensive. Thankfully, there are steps you can take to slow the wear and tear on your system.

• Monitor for potential problems. Keeping an eye out for problems, for instance by routinely checking your thermostat and energy bills, helps you resolve them before they get too expensive.
• Keep your system clean. Keeping your indoor evaporator coil, grills, condenser fan blades, and ductwork clean helps your system function optimally and reduces the risk 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. Keeping your blinds closed in the summer helps block out passive solar heat. Keeping them open in the winter helps you take advantage of this same heat. Both of these measures help reduce the strain on your HVAC system.
• Change filters regularly. Air flows through your HVAC system most effectively when you replace or clean the filters every 1–3 months. Also try not to let debris pile up on the outside areas of your HVAC.

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is important for a successful project. Partnering with an experienced, licensed contractor can offer you peace of mind and make sure your system provides reliable air conditioning and heating for your home.

Compare Multiple Bids

Contact at least three HVAC providers 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

Choose an HVAC company with highly trained technicians who have appropriate 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, contractors must pass an exam (the specific exam depends on what kind of equipment they intend 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 needs to have at least three years of experience and must show proof of both general liability and property damage insurance. You should also check reviews and complaints on sites like Yelp, Google Reviews, and the Better Business Bureau (BBB). Choose a company with positive reviews and testimonials about good customer experiences.

Understand Work Details

Always make sure you understand what a company’s process is like. When HVAC repairs are needed, ask your provider to explain which parts require replacement and why. Confirm that your technician will clean and test the full system after finishing the work to verify proper operation. When getting a replacement, ask the contractor to explain the new HVAC system model, brand, estimated installation time, energy efficiency, and features. Before work begins, you should understand the process your provider will use to properly size the system for your home and the price you'll pay.

Compare Warranties

Trustworthy HVAC companies back their work with warranties. Compare warranties from different companies, bearing in mind that more comprehensive coverage is better. Look for the provider that offers the most coverage for a fair price.

Get Quote in Writing

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