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:

HVAC Unit Type Cost
Split $2,503-$6,380
Hybrid Split $5,071-$9,343
Heat Pump $3,927-$40,010
Packaged Heating and Air $329-$548

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 keep your HVAC system working efficiently and lowers 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 open in the winter helps you take advantage of passive solar heating. Keeping them closed in the summer helps keep some of this heat out. Both of these measures help reduce the amount of work your HVAC system needs to do.
  • 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. Cleaning or replacing your air filters every 1–3 months helps air flow efficiently through your system. Also try to keep debris away from the outdoor portions of your HVAC system as much as possible.

Service Cost
Filter Replacement $82-$219
Condensor Cleaning $1,643-$4,929
Thermostat Repair $110-$274
Ductwork Cleaning $526-$1,314

How To Choose a Local HVAC Company

Knowing the right things to look for in an HVAC company is key for a smooth repair or installation. Picking an established business with certified technicians gives you assurance your HVAC system will deliver consistent coolig and heating year-round.

Compare Multiple Bids

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

Check Credentials

When hiring an HVAC provider, choose one with technicians that have the right training, licenses, and experience. In all states, HVAC contractors need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for any individual who helps "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." Contractors must pass an exam (the type of exam depends on what kind 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 hold 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). You want to hire a provider with glowing reviews and stories of positive service experiences.

Understand Work Details

Always make sure you know what a company’s process looks like. When HVAC repairs are needed, ask your provider to specify which parts need replacement and explain why. Confirm that your technician will clean and test the full system afterward to ensure proper operation. When replacing your HVAC, ask the provider to explain the new estimated installation time, model, features, energy efficiency, and brand. Before signing paperwork, be sure you understand how your provider will determine the right system size for your home and what the price will be.

Compare Warranties

Reputable HVAC companies back their work with warranties. Look at warranties from different companies, keeping 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

Always get HVAC bids in writing before work begins. A comprehensive quote covers costs for both labor and materials. Make sure that you agree to all terms before signing the contract.

Frequently Asked Questions About HVAC in Baltimore, MD

Typically, you should have your HVAC system inspected twice a year. After that inspection, your HVAC technician will tell you what services are needed. You should also have an inspection if you notice any new issues, like strange noises, leaks, or unusual smells. If you have ductwork in your home, it should be serviced every few years.

The best times to have an HVAC inspection are during the spring and fall. Technicians are generally less busy during these times, which makes it easier to get an appointment. This also ensures that your system is ready for the summer and winter, when it typically sees the most use.

You can save energy throughout the year by making it easier 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 try to adjust it only a few degrees at a time. You may also consider purchasing a smart thermostat.

It takes between one and three days to have your HVAC system installed or replaced. If you only need an air conditioning unit or a furnace, this may take anywhere from a few hours up to two days. This timeline can be affected by the size of your house, the accessibility of your system, and any issues your technician runs into.

For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. If your home is larger than 1,000 square feet, central air will be more effective for cooling than window units.

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).

Typically, HVAC financing is offered through a third-party lender. If your HVAC company doesn't offer these options, you may consider taking out a loan on your own. Be sure to talk to your HVAC company and a financial advisor to determine what options are available and appropriate for your situation.

There are several ways you can make your HVAC system more energy-efficient:

  • Keep your air ducts clean and change or clean your air filters on a regular basis.
  • 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 don't want to or can't buy one, try keeping the temperature indoors as close to the outside temperature as is comfortable.
  • When you need to replace part of your HVAC system, explore Energy Star-certified or similar environmentally friendly options.
