Signs You May Need HVAC Repair or Replacement

A faulty or aging HVAC system probably needs professional attention from a technician who can make fixes or install a new unit. Look out for these common indicators that your HVAC needs service:

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

These HVAC red flags indicate that you should have your system evaluated. A local company can complete an inspection, identify problems, and recommend repairing or replacing your HVAC unit.

Cost of HVAC Installation and Maintenance in Oyster Bay

HVAC installation or maintenance prices vary depending on your system. Common HVAC unit types include the following:

  • Split or mini-split: If your home's ductwork isn’t suited for a central HVAC system, you likely have a split or mini-split system. Split systems have internal units in each room to control temperature; these indoor units all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system works almost the same as a standard split system. It has the benefit of being able to utilize either electricity or gas for power.
  • Heat pump: Heat pumps transfer hot and cold air between your house and outside. They don't generate their own heating and cooling, so they work more efficiently in more moderate climates.
  • Packaged heating and air: Packaged HVAC systems are more popular in smaller houses. They consist of a single combined heating and cooling unit, usually located in an attic or basement. This unit tends to be efficient, compact, and easy to maintain.

The amount you spend on HVAC maintenance also depends on the kind of work you're having done. HVAC systems are complicated and might require different kinds of maintenance. The prices of some common jobs are as follows:

HVAC Unit TypeCost
Split$1,970-$5,022
Hybrid Split$3,992-$7,354
Heat Pump$3,091-$31,494
Packaged Heating and Air$259-$431

Ways to Save Money on HVAC Costs

Fixing your HVAC by repairing or replacing parts when needed is crucial, but can be expensive. Fortunately, 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 routinely checking your thermostat and energy bills, lets you resolve them before they get too expensive.
  • Change the position of your blinds seasonally. Leaving your blinds open during the colder months allows passive solar heating to warm your home. Closing the blinds in warmer seasons helps prevent the heat from getting inside. Doing both helps reduce the demand on your HVAC system.
  • Change filters regularly. Cleaning or replacing your air filters every 1–3 months helps air flow smoothly through your system. Also try to keep debris away from the outdoor portions of your HVAC system as much as possible.
  • Keep your system clean. Keeping your indoor evaporator coil, condenser fan blades, ductwork, and grills clean helps your HVAC system function effectively and lowers your risk of mold. The National Air Duct Cleaners Association recommends cleaning your HVAC system when you notice it starting to get dirty.
ServiceCost
Filter Replacement$65-$172
Condensor Cleaning$1,293-$3,880
Thermostat Repair$86-$216
Ductwork Cleaning$414-$1,035

How To Choose a Local HVAC Company

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

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 contractor'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 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 specific 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 on a state-by-state basis.

There is no state-level HVAC licensing in New York. 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. Checking reviews on the Better Business Bureau (BBB), Yelp, Google Reviews, and similar sites can aid your decision. Choose a company with stellar reviews and stories of positive experiences from customers.

Understand Work Details

Always make sure you know what a company’s process looks 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, request that the company explain the new features, brand, estimated installation time, model, and energy efficiency. Before signing a contract, make sure you understand how your provider will determine the right system size for your home and what the price will be.

Compare Warranties

A trustworthy HVAC company will back its repair services and installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully review warranty terms for each contractor and choose the company that provides the greatest protection within your budget.

Get Quote in Writing

Always get estimates for HVAC service in writing before work begins. A comprehensive quote should cover both materials and labor. Make sure you understand all terms before signing a contract.

Frequently Asked Questions About HVAC in Oyster Bay, NY

You should have your HVAC system inspected twice yearly. Following an inspection, your technician will inform you what services are needed. You should also call a technician if you notice new issues such as unusual smells, leaks, or strange noises. If your home has ductwork, you should have it inspected every few years.

Usually, 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 probably 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. 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 once. You may also consider a smart thermostat.

For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. If your home is larger than 1,000 square feet, central air will usually be more effective than window units for cooling.

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).

Your HVAC company may have financing options via a third-party lender, or you may 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 find the best option for you.

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

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