Signs You May Need HVAC Repair or Replacement

If your home's HVAC system isn't working correctly or nearing the end of its lifespan, you might need an HVAC contractor for maintenance or replacement. Look for these common signs that your system requires professional attention:

• Higher than normal energy bills
• Rust, cracking, or corrosion
• Frequent breakdowns and need for repairs
• Refrigerant leaks
• Odd noises when the system turns on

Cost of HVAC Installation and Maintenance in Kemp Mill

HVAC installation or maintenance costs vary depending on your system. Common HVAC unit types include the following:

• Split or mini-split: Homes without ductwork for central heating and cooling frequently have split or mini-split HVAC systems. These systems consist of internal units in each room to regulate temperature, which all connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions much like a standard split system, but is able to utilize either electricity or gas as energy sources.
• Heat pump: Heat pumps work by circulating hot and cold air between your home and the outdoors. These systems don't produce heat or air conditioning themselves, and are more effective in more moderate climates.
• Packaged heating and air: Packaged HVAC systems are more popular in smaller houses. These systems consist of a single heating and cooling unit, typically located in an attic or basement. This unit tends to be efficient, compact, and easy to maintain.

The cost of HVAC maintenance also depends on the kind of work being done. HVAC systems are complicated and can 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 take care of HVAC repairs and replacements when they are required, though they can be expensive. The good news is that homeowners have ways to reduce gradual wear and tear and reduce the frequency of breakdowns.

• Keep your system clean. Cleaning your ductwork, indoor evaporator coil, grills, and condenser fan blades regularly helps keep your HVAC system working efficiently and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system once it starts to look dirty.
• Monitor for potential problems. Monitoring your system for issues — for example, by checking your thermostat and energy bills routinely — helps you catch issues before they get too expensive.
• Change filters regularly. Air flows most effectively through your HVAC system when you change out or clean the filters every 1–3 months. Also avoid letting debris pile up on the outside areas of your HVAC.
• Change the position of your blinds seasonally. During winter, leaving your blinds open allows your home to benefit from passive solar heating. In the summer, keeping your blinds shut helps to block out heat. Doing both helps minimize the amount of work your HVAC system is required to do.

How To Choose a Local HVAC Company

Knowing what makes a trustworthy HVAC company is vital for a successful 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

Contact at least three HVAC providers for quotes. Explain the issues and have specialists visit to inspect your system if possible. Compare the contractors' explanations, solutions, estimated costs, warranties, and timeframes. Avoid providers that pressure you or demand payment upfront.

Check Credentials

When looking for an HVAC company, choose one with technicians that have the right training, licenses, and experience. HVAC contractors in all states need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for any individual who helps "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 at the state level.

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 have both general liability and property damage insurance. You should also check a provider's reviews and complaints with organizations such as Yelp, Google Reviews, and the Better Business Bureau (BBB). Choose a provider with glowing reviews and stories of positive service experiences.

Understand Work Details

Always make sure you understand the details of your project. When HVAC repairs are required, your provider should detail which parts need replacement and why. Confirm that your technician will clean and test the full system after repairs are finished to verify that it’s working properly. When replacing your HVAC system, ask the contractor to provide details on the new energy efficiency, estimated installation time, brand, features, and model. Before signing a contract, make sure you understand how your provider will properly size the new unit for your home and what the cost will be.

Compare Warranties

Trustworthy HVAC companies stand behind their services with warranties. Compare warranties from different companies, bearing in mind that broader coverage is better. Look for the provider that offers the most coverage for a fair price.

Get Quote in Writing

Always get HVAC bids in writing before work begins. A thorough quote will cover costs for both materials and labor. Confirm that you agree to all terms before signing the contract.
