Signs You May Need HVAC Repair or Replacement

If your HVAC system is faulty or getting old, it likely needs servicing or replacement from an HVAC company. Look for these indicators your system needs service:

  • Poor air circulation or uneven heating/cooling
  • Rust, cracking, or corrosion
  • Frequent breakdowns and need for repairs
  • Temperature control issues or thermostat malfunctions
  • Unusually high energy bills
  • Refrigerant leaks
  • Strange noises when the system turns on
  • An HVAC system that's over 15 years old

If you notice any of these HVAC issues, have a technician inspect your system. A local professional can diagnose problems and let you know whether whether fixing or replacing your HVAC unit is the best solution.

Cost of HVAC Installation and Maintenance in Elwood

What you pay for HVAC installation or maintenance varies based on your system type. Common HVAC unit styles include the following:

  • Split or mini-split: If your home's ductwork can't accommodate a central HVAC system, you likely have a split or mini-split system. Split systems have internal units in each room to regulate temperature; these indoor units all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system operates similar to a normal split system, but has the advantage of being able to utilize energy from either electric or gas sources.
  • Heat pump: Heat pumps work by circulating warm and cool air between your home and the outdoors. These systems don't produce heat or air conditioning themselves, and are better for more moderate climates.
  • Packaged heating and air: Packaged HVAC systems are good for smaller houses. They consist of a single heating and cooling unit that's normally located in an attic or basement. This unit tends to be efficient, compact, and easy to maintain.

HVAC maintenance costs differ depending on what services are needed. HVAC systems are complicated and might require different kinds of maintenance. Fees for some common services are as follows:

HVAC Unit TypeCost
Split$1,948-$4,966
Hybrid Split$3,947-$7,272
Heat Pump$3,056-$31,141
Packaged Heating and Air$256-$426

Ways to Save Money on HVAC Costs

Taking care of necessary HVAC repairs and replacements when needed is important, but can be expensive. Thankfully, there are steps you can take to slow the wear and tear on your system.

  • Monitor for potential problems. Keeping an eye out for problems, for instance by consistently checking your thermostat and energy bills, lets you resolve them before they get too expensive.
  • Change filters regularly. Air flows through your HVAC system most effectively when you replace or clean the filters every 30–90 days. Also try not to let debris pile up on the outside areas of your HVAC.
  • Keep your system clean. Keeping your condenser fan blades, indoor evaporator coil, grills, and ductwork clean helps your HVAC system function effectively and lowers the risk of mold. The National Air Duct Cleaners Association recommends cleaning your home's HVAC system when you notice things starting to get dirty.
  • Change the position of your blinds seasonally. Keeping your blinds closed in the summer helps block out passive solar heat. Keeping them open in the winter helps you take advantage of this same heat. Both of these measures help reduce the frequency with which you need to run your HVAC.
ServiceCost
Filter Replacement$64-$170
Condensor Cleaning$1,279-$3,836
Thermostat Repair$85-$213
Ductwork Cleaning$409-$1,023

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is important for a successful project. Look for an experienced, licensed contractor that 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 at least three HVAC contractors. Explain your issues and ask if technicians can inspect your system in person. Compare each company's diagnoses, recommended solutions, estimated cost, warranties, and timelines. Avoid companies that pressure you or demand payment before work.

Check Credentials

It's important to choose an HVAC company that employs technicians with the proper qualifications and expertise. HVAC contractors in all states have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, an individual 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 at the state level.

There is no state-level HVAC licensing in New York; however, many cities and municipalities have their own requirements, so be sure to check with your local government. For example, in some cases, a technician may need a High Pressure Boiler Operating Engineer or Oil Burning Equipment Installer license from the NYC Department of Buildings, or a Certificate of Qualification for Refrigerating System Operating Engineer from the Fire Department of New York. You should also read reviews and complaints on sites like Yelp, Google Reviews, and the Better Business Bureau (BBB). Choose a company with positive reviews and testimonials about good customer experiences.

Understand Work Details

Make sure you know the details of any project before starting. When getting HVAC repairs, have your provider detail which parts need replacement and why. Get confirmation that your technician will clean and test the entire system after the repair to verify that everything works. For replacement, ask the contractor to explain the new HVAC system features, brand, model, estimated installation time, and energy efficiency. Before work begins, 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

Trustworthy HVAC companies back their work with warranties. Look at warranties from different companies, remembering that more comprehensive coverage is better. Look for the provider that offers the most coverage for a fair price.

Get Quote in Writing

Get a written proposal before HVAC work starts. A full 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 Elwood, NY

Generally, 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 an inspection if you notice any new issues, such as leaks, strange noises, or unusual smells. If your home has ductwork, it should be serviced every few years.

The best times to have your HVAC system inspected are during the spring and fall. Technicians are generally less busy during these times, making it easier to get an appointment. 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 your home's temperature. 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 once. You may also consider installing a smart thermostat.

It takes roughly one to three days to have your HVAC system installed or replaced. If you only need an air conditioning unit or a furnace, this may take between half a day and two days. This timeline can be affected by the size of your home, how easily accessible your system is, and any new issues your technician runs into.

For a 2,000-square-foot home, try to purchase a furnace that's between 50,000 and 80,000 BTUs (British thermal units).

For a 2,000-square-foot home, you'll also want to look for an air conditioning unit with around 2.5 to 5 tons of capacity. Typically, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.

Your HVAC company might offer financing options through a third-party lender, or you may be able to obtain your own loan. It's a good idea 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:

  • Make sure your air ducts remain clean, and clean or change your air filters on a regular basis.
  • Schedule regular inspections to take care of issues as they arise.
  • 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 keeping your inside temperature as close to the outside temperature as you can.
  • When you need to replace part of your system, see if there are Energy Star-certified or other environmentally friendly options.
