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 reduces 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 avoid letting debris pile up on the outdoor parts of your HVAC.
  • Monitor for potential problems. Keeping an eye out for problems, for instance by routinely checking your thermostat and energy bills, lets you resolve them 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 decreases 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 what to look for in an HVAC company is important for a successful project. Partnering with an experienced, licensed contractor can offer you peace of mind and make sure your system provides reliable heating and air conditioning for your home.

Compare Multiple Bids

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

Check Credentials

It's important to choose an HVAC company that employs technicians with the appropriate qualifications and expertise. In all states, HVAC contractors have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, a contractor must pass an exam (the type of exam depends on what 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.

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, possess a minimum amount of contractor liability coverage, and pass an exam. Specific jurisdictions may have additional licensing requirements. You should also check a company's reviews and complaints with organizations such as the Better Business Bureau (BBB), Yelp, and Google Reviews. Choose a company with positive reviews and a history of good customer service.

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 require replacement and explain why. Confirm that your technician will clean and test your system at the end of the job to ensure proper operation. When replacing your HVAC, request that the installation company describe the new features, brand, model, estimated installation time, and energy efficiency. Before signing a contract, 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

A reputable HVAC company will stand behind its repair work and installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully compare warranty terms between contractors and choose the company that provides the most protection at a reasonable price.

Get Quote in Writing

Get a written proposal before HVAC work starts. A comprehensive quote includes both labor and material costs. Make sure you understand and agree to all terms before signing the contract.

Frequently Asked Questions About HVAC in Union, OH

You should have your HVAC system inspected about twice annually. At the time of the inspection, your technician will inform you if any services are required. You should also schedule an inspection if you notice new issues such as unusual smells, strange noises, or leaks. If your home 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 technicians tend to be less busy at these times. This also helps make sure your system is prepared for the summer and winter, when it likely 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. During all seasons, keep your thermostat as close to the outside temperature as you can, and try to adjust it only a few degrees at once. You could also consider a smart thermostat.

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 generally be more effective for cooling than window units.

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

Typically, HVAC financing is provided by 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 speak with a financial advisor and your HVAC company to find out what options are available to you 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 regularly.
  • Schedule 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 don't want to or can't buy one, try keeping your inside temperature as close to the outside temperature as you can.
  • When replacing part of your HVAC system, see if there are Energy Star-certified or similar environmentally friendly options.
