Signs You May Need HVAC Repair or Replacement

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

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

Schedule an inspection if you notice any of these problems. A local technician can assess your system, detect problems, and determine whether you need repairs or a new HVAC unit.

Cost of HVAC Installation and Maintenance in Stony Brook

Your HVAC installation or maintenance cost changes depending on the type of unit. Common HVAC unit types include the following:

  • Split or mini-split: If your home lacks the right ductwork for central heating or air, you probably have a split HVAC system. Split or mini-split systems consist of internal units that control the temperature in individual rooms, and that are all connected to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions very similarly to a standard split system. It has the benefit of having the capability to use either electricity or gas for power.
  • Heat pump: Heat pumps work by circulating hot and cold air between your home and the outdoors. These systems don't generate heat or air conditioning themselves, and are more effective in more moderate climates.
  • Packaged heating and air: Packaged HVAC systems work best in smaller homes. They consist of a single combined heating and air conditioning unit, commonly located in a basement or attic. This unit is typically space-saving, cost-effective, and easy to maintain.

HVAC maintenance prices differ based on the specific services required. HVAC systems can be complicated and potentially require a number of services. Fees for typical jobs 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

HVAC upkeep is important, but can be pricey. Thankfully, there are steps homeowners can take to reduce wear and tear on their system and lower future maintenance needs.

  • Change the position of your blinds seasonally. Closing your blinds in the summer blocks some passive solar heat from getting indoors. Opening the blinds in the winter allows this same heat to help warm your home. Both of these measures help decrease the work required from your house's HVAC system.
  • Keep your system clean. Cleaning your condenser fan blades, indoor evaporator coil, grills, and ductwork 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 begins to look dirty.
  • Change filters regularly. Cleaning or replacing your air filters every 30–90 days helps air flow smoothly through your system. Also try to keep debris away from the outside areas of your HVAC system as much as possible.
  • Monitor for potential problems. Keep an eye on your system for issues, for example by routinely checking your thermostat and energy bills. This enables you to address issues before they get too expensive.
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

Finding the right HVAC company is crucial for a smooth installation or repair. Hiring 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 companies. Describe your issues and ask if technicians can inspect your system in person. Review each provider's diagnoses, recommended solutions, estimated cost, warranties, and timeline. Avoid companies that pressure you or demand payment before work.

Check Credentials

Look for an HVAC company that employs skilled technicians who have the necessary licensure and training. HVAC contractors in all states must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for all technicians who "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 the type of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled on a state-by-state basis.

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 look at a company's reviews and complaints on sites such as Google Reviews, Yelp, and the Better Business Bureau (BBB). Pick a company with glowing feedback and good customer testimonials.

Understand Work Details

Make sure you know the details of your project before it begins. If HVAC repairs are required, have your provider list which parts require replacement and why. Confirm that your technician will clean and test the system after the repair to verify that everything works. For replacement, ask the contractor to explain the new HVAC system model, estimated installation time, energy efficiency, features, and brand. Before work begins, you should understand how your provider will size the system appropriately for your home and the price you'll pay.

Compare Warranties

A reputable HVAC company will stand behind its repair services and equipment installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully compare warranty terms between contractors and choose the provider that offers the best protection within your budget.

Get Quote in Writing

Get written estimates before beginning any HVAC work. The quote should outline costs for both labor and materials. Review all terms carefully before signing.

Frequently Asked Questions About HVAC in Stony Brook, NY

You should have your HVAC system inspected about twice annually. After completing their inspection, your technician will tell you if any services are required. You should also have your system inspected if you notice new issues such as leaks, unusual smells, or strange noises. If your system 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 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 throughout the year by reducing the amount of power your HVAC system uses to maintain your home's temperature. Always keep your thermostat as close to the outside temperature as you can, and try to adjust it only a few degrees at once. You might also consider installing a smart thermostat.

It takes between one and three days to have an HVAC system installed or replaced. If you only need an air conditioning unit or a furnace, this can take anywhere from a few hours up to two days. This timeline will be affected by the size of your home, how easily accessible your system is, and any issues your technician uncovers.

For a 2,000-square-foot home, you'll want 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 purchase an air conditioning unit with between 2.5 and 5 tons of capacity. In general, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.

Your HVAC company might offer financing options via a third-party lender, or you may be able to obtain a loan on your own. It's smart to discuss payment options with your HVAC company and a financial advisor to make sure that you find the best option for you.
