Signs You May Need HVAC Repair or Replacement

A malfunctioning or aging HVAC system probably needs professional attention from a technician who can make repairs or install a new unit. Look out for these common signs that your HVAC needs service:

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

If you notice any of the above, have a local HVAC technician inspect your system. They can diagnose problems and determine whether repair or full HVAC replacement is required.

Cost of HVAC Installation and Maintenance in Clarksburg

Your HVAC installation or maintenance cost varies depending on the type of unit. Common HVAC unit types 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 indoor units in each room to control temperature. These connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC unit operates similarly to a regular split system. It provides flexibility by providing the option to draw on either electricity or gas for energy.
  • Heat pump: Heat pumps work by moving warm and cool air between your home and the outdoors. These systems don't generate heat or air conditioning themselves, and are better for more moderate climates.
  • Packaged heating and air: Packaged HVAC systems are good for smaller houses. Packaged 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 based on the specific services needed. HVAC systems can be complicated and potentially require a number of services. Price ranges for typical jobs are as follows:

HVAC Unit TypeCost
Split$1,976-$5,038
Hybrid Split$4,004-$7,378
Heat Pump$3,101-$31,594
Packaged Heating and Air$259-$432

Ways to Save Money on HVAC Costs

It’s important to make any essential HVAC fixes or 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.

  • Change the position of your blinds seasonally. During winter, leave your blinds open so your home benefits from passive solar heat. In summer, keep blinds shut to block out heat. Doing both reduces the amount of work your HVAC system is required to do.
  • Change filters regularly. Cleaning or replacing your air filters every 30–90 days helps air flow smoothly through your system. You should also try to keep debris away from the outside areas of your HVAC system as much as possible.
  • 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 out of hand.
  • Keep your system clean. Cleaning your condenser fan blades, ductwork, grills, and indoor evaporator coil 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 begins to look dirty.
ServiceCost
Filter Replacement$65-$173
Condensor Cleaning$1,297-$3,892
Thermostat Repair$86-$216
Ductwork Cleaning$415-$1,038

How To Choose a Local HVAC Company

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

Compare Multiple Bids

Contact at least three HVAC providers for quotes. Describe your issues and schedule an in-person inspection if possible. Compare contractors' diagnoses, suggested repairs, estimated costs, warranties, and timeframes. Avoid providers that pressure you or demand upfront payment.

Check Credentials

Choose an HVAC company with well-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, individuals must pass an exam (the type of exam depends on the kind of equipment they plan 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 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 hold both property damage and general liability insurance. Also check a company's reviews and complaints on sites such as the Better Business Bureau (BBB), Yelp, and Google Reviews. Pick a company with glowing feedback and stories of satisfied customers.

Understand Work Details

Always make sure you know what a company’s process is like. When getting HVAC repairs, ask your provider to specify which parts need replacement and explain why. Confirm that your technician will clean and test the full system after finishing the work to ensure proper operation. When replacing your HVAC system, request that the installation company describe the new energy efficiency, estimated installation time, features, model, and brand. Before work starts, ask about the process your provider will use to properly size the new system for your home and how much it will cost.

Compare Warranties

Reliable HVAC companies offer warranties on repairs and equipment installations. The more complete the coverage, the better. Review warranty details between companies and pick the one that provides the most comprehensive protection for a fair price.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Clarksburg, MD

You should have your HVAC system inspected about twice a year. After completing their inspection, your technician will inform you if any services are required. You should also call a technician if you notice new issues such as leaks, strange noises, or unusual smells. If your system has ductwork, you should have it inspected every few years.

Normally, it's smart to have your HVAC system inspected in the spring and fall, as these times tend to be less busy. This also helps get your system ready for the summer and winter, when it typically sees the most use.

You can save energy throughout the year by reducing the amount of work it takes for your HVAC system to maintain the temperature of your home. During all seasons, keep your thermostat as close to the outside temperature as is comfortable, and avoid making drastic changes — adjust it only a few degrees at a time. You might also consider a smart thermostat.

For a 2,000-square-foot home, you'll need between 2.5 and 5 tons of air conditioning capacity. For a house over 1,000 square feet, central air is likely to be more effective than window units for cooling.

For a 2,000-square-foot home, you'll also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units).

Usually, HVAC financing is through a third-party lender. If your HVAC company doesn't offer financing, you could consider taking out a loan on your own. Be sure to speak with your HVAC company and a financial advisor to find out what options are available and appropriate for your situation.

There are a number of ways you can make your HVAC system more energy-efficient:

  • Keep your air ducts clean and change or clean your air filters regularly.
  • Have regular inspections to take care of problems as they arise.
  • Make sure your doors and windows are well-sealed and keep your attic well-ventilated.
  • Install a smart thermostat. If you aren't able to purchase one, try to keep your inside temperature as close to the outside temperature as you can.
  • When replacing part of your system, explore Energy Star-certified or similar environmentally friendly options.
