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 indicators your system needs service:

  • Refrigerant leaks
  • Frequent breakdowns and need for repairs
  • Uneven heating/cooling or poor air circulation
  • Cracking, corrosion, or rust
  • Higher than normal energy bills
  • Temperature control issues or thermostat malfunctions
  • Odd noises when turning on
  • An HVAC system that's over 15 years old

Arrange an inspection if you notice any of these problems. A local technician can assess your system, detect problems, and determine whether you need to fix or replace your HVAC.

Cost of HVAC Installation and Maintenance in North Bethesda

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

  • Split or mini-split: If your home lacks the ductwork for central heating and cooling, you likely have a split or mini-split system instead. Split HVAC systems have internal units in each room to manage temperature. These 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 for power.
  • Heat pump: Heat pumps transfer hot and cold air between your home and the outside. These systems don't generate their own heat or AC, so they work more effectively in more temperate climates.
  • Packaged heating and air: Packaged HVAC systems are more popular in smaller houses. These systems consist of a single combined heating and cooling unit, normally located in an attic or basement. This unit tends to be compact, efficient, and easy to maintain.

HVAC maintenance prices vary based on the services needed. HVAC systems are complicated and may need several types of maintenance. Prices for common jobs are as follows:

HVAC Unit Type Cost
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 complete repairs or full-system HVAC replacements as needed, 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.

  • Change the position of your blinds seasonally. Leaving your blinds open during the colder months allows passive solar heating to warm your home. Closing the blinds during the summer helps prevent the heat from getting inside. Doing both helps decrease the demand on your HVAC.
  • Change filters regularly. Cleaning or replacing your air filters every 30–90 days helps air flow efficiently through your system. You should also try to keep debris away from the external sections of your HVAC system as much as possible.
  • Keep your system clean. Keeping your indoor evaporator coil, grills, condenser fan blades, and ductwork clean helps your system run and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends that you clean your HVAC system whenever it begins to look dirty.
  • Monitor for potential problems. Keep an eye on your system for issues, for example by consistently checking your thermostat and energy bills. This helps you address issues before they get too expensive.

Service Cost
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 makes a trustworthy HVAC company is key for a smooth installation or repair. An experienced, credentialed HVAC contractor gives you confidence your system can provide reliable heating and air conditioning year-round.

Compare Multiple Bids

Get quotes from at least three HVAC companies. Explain your issues and ask if technicians can inspect your system in person. Review each contractor's diagnoses, recommended solutions, estimated cost, warranties, and timelines. Avoid companies that pressure you or demand payment before work.

Check Credentials

Choose an HVAC company with highly trained technicians who have proper licensing and experience. In all states, HVAC contractors 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 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 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 needs to have at least three years of experience and must hold both property damage and general liability insurance. Reviewing feedback on Google Reviews, the Better Business Bureau (BBB), Yelp, and similar sites can help your decision as well. Choose a provider with stellar reviews and reports of positive customer experiences.

Understand Work Details

Always make sure you understand the details of your project. For HVAC repairs, 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 ensure that it’s working properly. For replacement, ask the contractor to explain the new HVAC system features, model, brand, energy efficiency, and estimated installation time. Before work begins, you should understand how your provider will size the system appropriately for your home and the price you'll pay.

Compare Warranties

Reliable HVAC companies offer warranties on service and installations. The more complete the coverage, the better. Review warranty details between companies and pick the one that offers the best protection within your budget.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in North Bethesda, MD

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

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

You can save energy throughout the year by reducing the amount of power your HVAC system uses to maintain your home's temperature. Always keep your thermostat as close to the outside temperature as possible, and try to adjust it only a few degrees at once. You could also consider getting a smart thermostat.

It takes roughly one to three days to have your HVAC system installed or replaced. If you only need a furnace or a single air conditioning unit, this might 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 uncovers.

For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. For a house over 1,000 square feet, central air will usually 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).

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.
  • Schedule regular inspections to take care of problems as they come up.
  • 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 you can.
  • When replacing part of your HVAC system, explore Energy Star-certified or similar environmentally friendly options.
