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. Keep an eye out for these common indicators that your HVAC needs service:

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

If you're experiencing any of these HVAC issues, you should have a technician inspect your system. A local professional can detect problems and decide whether repairing or getting a new HVAC unit is the best solution.

Cost of HVAC Installation and Maintenance in Greenlawn

Your HVAC installation or maintenance cost fluctuates depending on the style of unit. Common HVAC unit varieties include the following:

  • Split or mini-split: If your home's ductwork isn’t suited for a central HVAC system, you probably have a split or mini-split system. Split systems have interior units in each room to regulate temperature; these indoor units all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system performs similarly to a standard split system, but has the capacity to draw on either electricity or gas as energy sources.
  • Heat pump: Heat pumps work by transferring hot and cold air between your home and the outdoors. These systems don't generate heat or air conditioning themselves, and are better for more moderate climates.
  • Packaged heating and air: Packaged HVAC systems are a good choice for smaller houses. They have a single cooling and heating unit, usually in an attic or basement. This unit is often space-saving, cost-effective, and easy to maintain.

HVAC costs differ based on the work needed. HVAC systems are complex and may need multiple types of maintenance. Prices for common 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

It's important to fix or swap out your HVAC components when they become damaged, but it can also be expensive. Thankfully, there are steps you can take to slow the wear and tear on your system.

  • Keep your system clean. Regularly cleaning condenser fan blades, indoor evaporator coil, grills, and ductwork helps keep your HVAC system running efficiently and reduces your risk of mold. The National Air Duct Cleaners Association advises cleaning your system when it starts to look dirty.
  • 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 home’s HVAC system.
  • Monitor for potential problems. Monitoring the efficiency of your HVAC system — for instance by checking your thermostat settings and energy bills — helps you find and solve issues before they get too expensive.
  • Change filters regularly. Replacing or cleaning your air filters every 1–3 months helps air flow smoothly through your HVAC system. You should also try to prevent dirt and debris from building up around the external parts of your system.
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 makes a trustworthy HVAC company is key for a successful 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 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

When picking an HVAC company, choose one with technicians that have the appropriate training, licenses, and experience. In all states, HVAC contractors must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for all contractors 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, 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. You should also look at a company's reviews and complaints on sites such as the Better Business Bureau (BBB), Yelp, and Google Reviews. Pick a company with glowing feedback and stories of satisfied customers.

Understand Work Details

Always make sure you understand the details of any project. For HVAC repairs, your provider should list which parts require replacement and why. Confirm that your technician will clean and test the full system after repairs are completed to verify that it’s working properly. When replacing your HVAC system, request that the installation company describe the new features, model, brand, energy efficiency, and estimated installation time. 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 trustworthy HVAC company will back its repair services and installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully compare the fine print between contractors and choose the company that provides the best protection at a reasonable price.

Get Quote in Writing

Always get HVAC bids in writing before work begins. A detailed quote covers costs for both labor and materials. Confirm that you understand all terms before signing the contract.

Frequently Asked Questions About HVAC in Greenlawn, NY

Normally, your HVAC system should be inspected twice a year. After an inspection, your technician will tell you what services are needed. You should also call a technician if you start to notice any issues, such as strange noises, leaks, or unusual smells. If your home has ductwork, it should be serviced every few years.

The best times to have an HVAC inspection are during the spring and fall. Technicians are generally less busy during these times, making it easier to get an appointment. This also ensures that your system is ready for the summer and winter, the times of the year when it 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 possible, and avoid making drastic changes — adjust it only a few degrees at once. You might also consider a smart thermostat.

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

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 between 2.5 and 5 tons of capacity. Generally, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.

Normally, HVAC financing is offered 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 your HVAC company and a financial advisor to find out what options are available to you and appropriate for your situation.

There are several ways you can make your HVAC system more energy-efficient:

  • Keep ductwork clean, and clean or change your air filters regularly.
  • Have regular inspections to take care of problems as they arise.
  • 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 you need to replace part of your system, see if there are Energy Star-certified or other environmentally friendly options.
