Signs You May Need HVAC Repair or Replacement

A faulty 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:

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

If you notice any of these HVAC red flags, your system evaluated. A local company can complete an inspection, diagnose problems, and recommend repairing or replacing your HVAC unit.

Cost of HVAC Installation and Maintenance in Overlea

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

• Split or mini-split: If your home lacks the right ductwork for central heating or air, you likely have a split HVAC system. Split or mini-split systems consist of interior units that regulate the temperature in individual rooms, and that are all connected to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions comparably to a regular split system. It gives flexibility by having the option to draw on either electricity or gas for energy.
• Heat pump: Heat pumps transfer hot and cold air between your home and the outside. These systems don't make their own heat or AC, so they work more effectively in more temperate climates.
• Packaged heating and air: Packaged HVAC systems are often a good option for smaller houses. These systems consist of a single heating and cooling unit that's usually located in a basement or attic. This unit tends to be compact, efficient, and easy to maintain.

HVAC maintenance prices vary depending on what services are needed. HVAC systems are complicated and might require different maintenance services. Fees for common services are as follows:

Ways to Save Money on HVAC Costs

HVAC system repairs and replacements are important, but can be expensive. Fortunately, there are steps homeowners can take to reduce wear and tear on their HVAC and lower future maintenance needs.

• Monitor for potential problems. Monitoring your system for problems — for example, by checking your thermostat and energy bills routinely — helps you get ahead of problems before they get too expensive.
• Change filters regularly. Replacing or cleaning your air filters every 30–90 days helps air flow efficiently through your HVAC system. We also recommend regularly clearing dirt and debris away from the outdoor sections of your system.
• Keep your system clean. Cleaning your grills, ductwork, indoor evaporator coil, 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.
• Change the position of your blinds seasonally. Opening your blinds in winter allows passive solar heat into your house. Closing your blinds in summer blocks some heat from getting indoors. Both of these measures help decrease the work required from your house's HVAC system.

How To Choose a Local HVAC Company

It's important to know what makes a good HVAC company. Working with a contractor that's properly licensed and highly experienced will give you confidence that they can keep your system running efficiently, providing you with effective air conditioning and heating for your home.

Compare Multiple Bids

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

Check Credentials

It's important to choose an HVAC company that employs technicians with the proper qualifications and expertise. HVAC contractors in all states have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, an individual must pass an exam (the specific exam depends on the 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 must have at least three years of experience and must have both general liability and property damage insurance. Reviewing feedback on Google Reviews, Yelp, the Better Business Bureau (BBB), and similar sites can assist your decision. Choose a company with stellar reviews and reports of positive customer experiences.

Understand Work Details

Always make sure you understand the details of a planned project. For HVAC repairs, your provider should specify which parts require replacement and why. Confirm that your technician will clean and test your system after repairs are completed to ensure that it’s working properly. When replacing your HVAC, request that the company explain the new estimated installation time, model, features, brand, and energy efficiency. Before work starts, make 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

A trustworthy HVAC company will back its repair work and equipment installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully compare warranty terms between contractors and choose the provider that offers the best protection within your budget.

Get Quote in Writing

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