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 indicators that your system requires professional attention:

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

If you notice any of these HVAC red flags, your system evaluated. A local provider can complete an inspection, identify problems, and advise you whether you should repair or replace your HVAC unit.

Cost of HVAC Installation and Maintenance in Plymouth

Your HVAC installation or maintenance cost fluctuates depending on the type of unit. Common HVAC unit varieties include the following:

  • Split or mini-split: Homes without ductwork for central air often have split or mini-split HVAC systems. These systems consist of interior units in each room to regulate temperature, which all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions in the same way as a normal split system, but has the advantage of being able to utilize energy from either electric or gas sources.
  • Heat pump: Heat pumps circulate hot and cool air between your home and the outdoors. They don't make their own heat or AC, so they work best in temperate climates.
  • Packaged heating and air: Packaged HVAC systems are often a good option for smaller homes. These systems consist of a single combined heating and cooling unit, usually located in a basement or attic. This unit tends to be compact, efficient, and easy to maintain.

HVAC costs differ based on the work needed. HVAC systems are complicated and may need a number of types of maintenance. Costs for common jobs are as follows:

HVAC Unit TypeCost
Split$1,828-$4,660
Hybrid Split$3,704-$6,824
Heat Pump$2,868-$29,224
Packaged Heating and Air$240-$400

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 methods to decrease the effect of wear and tear and reduce the frequency of breakdowns.

  • Change filters regularly. Cleaning or replacing your air filters every 30–90 days helps air flow efficiently through your system. Also try to keep debris away from the external sections of your HVAC system as much as possible.
  • Monitor for potential problems. Monitor your system for issues, for example by consistently checking your thermostat and energy bills. This enables you to address issues before they get too expensive.
  • Change the position of your blinds seasonally. Leaving your blinds open during the winter helps warm your home with passive solar heating. Closing the blinds during the summer helps prevent the same heat from getting inside. Doing both helps reduce the strain on your HVAC.
  • 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 cleaning your HVAC system when it starts to look dirty.
ServiceCost
Filter Replacement$60-$160
Condensor Cleaning$1,200-$3,600
Thermostat Repair$80-$200
Ductwork Cleaning$384-$960

How To Choose a Local HVAC Company

It's important to know what makes a good HVAC company. A properly licensed contractor with the right experience will give you confidence that they can keep your system running efficiently, providing you with effective heating and cooling in your home.

Compare Multiple Bids

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

Check Credentials

When picking 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 all contractors who "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 what kind of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled by the state.

Indiana doesn't have any state-level licensing requirements for HVAC contractors; however, most municipalities and cities have their own regulations. Make sure that you check with your local government and verify the business license of any company you hire. You should also check a company's reviews and complaints with organizations such as the Better Business Bureau (BBB), Yelp, and Google Reviews. Look for a a company with positive reviews and a history of good customer service.

Understand Work Details

Make sure you understand the details of your project before starting. When getting HVAC repairs, have your provider list which parts need replacement and why. Get confirmation that your technician will clean and test the system after the repair to verify that everything works. For replacement, ask the contractor to explain the new HVAC system energy efficiency, brand, model, features, and estimated installation time. Before starting the project, you should understand the process your provider will use to properly size the system for your home and the price you'll pay.

Compare Warranties

Reliable HVAC companies provide warranties for their services. Broader coverage is better, so make sure to review warranties between providers. Choose the one that provides the most comprehensive coverage at a fair cost.

Get Quote in Writing

Get written quotes before starting any HVAC work. The quote should include costs for both materials and labor. Read all terms carefully before signing.

Frequently Asked Questions About HVAC in Plymouth, IN

You should have your HVAC system inspected twice yearly. After completing their inspection, your technician will tell you if any services are needed. You should also schedule an inspection if you notice new issues such as strange noises, unusual smells, or leaks. If your system has ductwork, you should have it inspected every few years.

Normally, it's a good idea to schedule inspections in the spring and fall, as technicians tend to be less busy at these times. This also helps get your system ready for the summer and winter, when it probably sees the most use.

You can save energy throughout the year by reducing the amount of power your HVAC system uses to maintain the temperature of your home. Always 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 installing a smart thermostat.

It takes around 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 can take anywhere from a few hours up to two days. This timeline can be influenced by the size of your house, how easily accessible your system is, and any new issues your technician discovers.

For a 2,000-square-foot home, you'll need between 2.5 and 5 tons of air conditioning capacity. If your home is larger than 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).

Your HVAC company might provide financing options through a third-party lender, or you might be able to obtain your own loan. It's smart to discuss payment options with a financial advisor and your HVAC company to make sure that you're choosing the best option for you.

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

  • Keep ductwork clean, and clean or change 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 aren't able to purchase one, try to keep your inside temperature as close to the outside temperature as is comfortable.
  • When it comes time to replace any part of your system, explore Energy Star-certified or other environmentally friendly options.
