Signs You May Need HVAC Repair or Replacement

If your HVAC system is having issues 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
  • Poor air circulation or uneven heating/cooling
  • Unusually high energy bills
  • Thermostat malfunctions or temperature control issues
  • Strange noises when the system turns on
  • Corrosion, rust, or cracking
  • An HVAC system that's over 15 years old

If you notice any of the above, it's wise to have a local HVAC technician inspect your system. They can identify problems and recommend whether repair or full HVAC replacement is the best course of action.

Cost of HVAC Installation and Maintenance in Ithaca

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

  • Split or mini-split: If your home lacks the right ductwork for central heating or air, you likely have a split HVAC system. Split or mini-split systems consist of internal units that regulate the temperature in individual rooms, and that are all connected to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions comparably to a regular split system. It gives flexibility by having the option to draw on either electricity or gas for energy.
  • Heat pump: Heat pumps work by circulating warm and cool air between your home and the outdoors. These systems don't create heat or air conditioning themselves, and are more effective in more moderate climates. They may not be as effective during Ithaca's cold winters.
  • 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 that's normally located in an attic or basement. This unit tends to be efficient, compact, and easy to maintain.

HVAC maintenance costs vary depending on what services are needed. HVAC systems are complicated and may require different maintenance services. Prices for common services are as follows:

HVAC Unit TypeCost
Split$1,947-$4,962
Hybrid Split$3,944-$7,266
Heat Pump$3,054-$31,119
Packaged Heating and Air$256-$426

Ways to Save Money on HVAC Costs

It's important to take care of HVAC repairs and replacements in a timely manner, but it can also be expensive. Thankfully, there are some steps you can take to slow the wear and tear on your system.

  • 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 in warmer seasons helps prevent some heat from getting inside. Doing both helps decrease the demand on your HVAC.
  • Keep your system clean. Regularly cleaning grills, condenser fan blades, ductwork, and indoor evaporator coil helps keep your HVAC system running efficiently and reduces your risk of mold. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.
  • 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 filters regularly. Air flows best through your HVAC system when you change out or clean the filters every 30–90 days. Also avoid letting debris pile up on the external sections of your HVAC.
ServiceCost
Filter Replacement$64-$170
Condensor Cleaning$1,278-$3,833
Thermostat Repair$85-$213
Ductwork Cleaning$409-$1,022

How To Choose a Local HVAC Company

Knowing what makes a trustworthy HVAC company is crucial for an easy installation or repair. An experienced, credentialed HVAC contractor gives you confidence your system can provide consistent heating and air conditioning year-round.

Compare Multiple Bids

Get quotes from three or more HVAC providers. Describe your issues and ask if technicians can inspect your system in person. Review each company's diagnoses, recommended solutions, estimated cost, timeline, and warranties. 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 appropriate qualifications and expertise. In all states, HVAC contractors have federal requirements from 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 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 on a state-by-state basis.

The state of New York doesn't have state-level HVAC licensing; however, there may be local requirements, so be sure to check with your city or municipal 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. Always check a provider's reviews and complaints with organizations such as Google Reviews, the Better Business Bureau (BBB), and Yelp. You want to hire a company with positive reviews and a history of good customer service.

Understand Work Details

Always make sure you understand what a company’s process is like. When getting HVAC repairs, ask your provider to explain which parts need replacement and why. Confirm that your technician will clean and test your system after finishing the work to verify proper operation. When replacing your HVAC, ask the provider to explain the new features, model, energy efficiency, estimated installation time, and brand. Before signing paperwork, make sure you understand the process your provider will use to size the new HVAC system appropriately for your home and what the price will be.

Compare Warranties

Trustworthy HVAC companies back their services with warranties. Look at warranties from different companies, keeping in mind that broader coverage is better. Look for the provider that offers the most coverage for a fair price.

Get Quote in Writing

Always get HVAC quotes in writing before work begins. A comprehensive 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 Ithaca, NY

You should have your HVAC system inspected twice yearly. After the inspection, your technician will tell you what services are needed. You should also call a technician if you start noticing issues such as strange noises, unusual smells, or leaks. If your system has ductwork, you should have it inspected every few years.

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

You can save energy during the winter by reducing the amount of work your HVAC system needs to do to heat your home. Keep your thermostat as low as you can and avoid making drastic changes in the temperature — increase or decrease it a few degrees at a time. If you're able to, try switching to a smart thermostat.

It takes roughly one to three days to have an 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 will be determined by the size of your house, the accessibility of your system, and any issues your technician discovers.

For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. In Ithaca, you can probably make do with a unit on the lower end of this range. For homes 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). In Ithaca, you might need a higher-capacity furnace.

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

There are several 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.
  • Schedule regular inspections to take care of issues 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 is comfortable.
  • When replacing part of your system, see if there are Energy Star-certified or other environmentally friendly options.
