Signs You May Need HVAC Repair or Replacement

An HVAC system that's broken or past its lifespan likely needs professional attention for maintenance or replacement. Watch for these signals that your system needs service:

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

These HVAC red flags indicate that you should have your system evaluated. A local technician 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 Union

What you pay for HVAC installation or maintenance depends on your system style. Common HVAC unit styles include the following:

  • Split or mini-split: Homes without ductwork for central heating and cooling 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 comparably 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 exchange warm and cool air between your house and the outdoors. They don't generate their own heating and cooling, so they work more efficiently in more temperate climates.
  • Packaged heating and air: Packaged HVAC systems are good for smaller homes. Packaged 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 maintenance costs vary depending on the particular service needed. HVAC systems are complex and might require different kinds of maintenance. Costs for some common services are as follows:

HVAC Unit TypeCost
Split$1,866-$4,757
Hybrid Split$3,781-$6,965
Heat Pump$2,927-$29,829
Packaged Heating and Air$245-$408

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 ductwork, grills, indoor evaporator coil, and condenser fan blades 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 once it starts to look dirty.
  • Change filters regularly. Air flows best through your HVAC system when you change out or clean the filters every 1–3 months. Also try not to let debris pile up on the outside areas of your HVAC.
  • Monitor for potential problems. Monitoring your system for problems — for example, by checking your thermostat and energy bills regularly — helps you get ahead of problems before they get too expensive.
  • 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 helps minimize the amount of work your HVAC system needs to do.
ServiceCost
Filter Replacement$61-$163
Condensor Cleaning$1,225-$3,675
Thermostat Repair$82-$204
Ductwork Cleaning$392-$980

How To Choose a Local HVAC Company

Knowing the indicators of a good HVAC company is important. A properly licensed contractor with the right experience 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

Get quotes from three or more HVAC companies. Describe your issues and ask if specialists can inspect your system in person. Compare each company's diagnoses, recommended solutions, estimated cost, warranties, and timeline. Avoid providers that pressure you or demand payment before work.

Check Credentials

When selecting an HVAC company, choose one with technicians that have the appropriate training, licenses, and experience. HVAC contractors in all states must 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." 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.

In Ohio, HVAC contractors are licensed by the Ohio Construction Industry Licensing Board. To obtain a license, contractors must have at least five years of experience, have a minimum amount of contractor liability coverage, and pass an exam. Your local jurisdiction may have additional licensing requirements. Reviewing feedback on the Better Business Bureau (BBB), Yelp, Google Reviews, and similar sites can aid your decision. Choose a company with stellar reviews and reports of positive customer experiences.

Understand Work Details

Always make sure you know the details of your project. When HVAC repairs are required, your provider should list which parts require replacement and why. Confirm that your technician will clean and test the system after repairs are finished to verify that it’s working properly. When replacing your HVAC, request that the installation company describe the new features, brand, model, estimated installation time, and energy efficiency. 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

Good HVAC companies offer warranties on service and installations. The more complete the coverage, the better. Compare warranty details between providers and pick the one that offers the most comprehensive protection for the fairest price.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Union, OH

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

Normally, it's best to have your HVAC system inspected 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 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 possible, and avoid making drastic changes — adjust it only a few degrees at a time. You might also consider purchasing a smart thermostat.

It takes roughly one to three days to have your HVAC system installed or replaced. If you need just an air conditioning unit or a furnace, this might take between half a day and two days. This timeline can be influenced by the size of your home, the accessibility of your system, and any issues your technician uncovers.

For a 2,000-square-foot home, you should look for around 2.5 to 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).

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

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

  • Make sure your air ducts remain clean, and change or clean your air filters on a regular basis.
  • Have regular inspections to take care of problems as they come up.
  • Keep your attic well-ventilated and make sure all doors and windows are well-sealed.
  • 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 replacing part of your system, explore Energy Star-certified or other environmentally friendly options.
