Signs You May Need HVAC Repair or Replacement

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

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

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

Cost of HVAC Installation and Maintenance in Sayville

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

  • Split or mini-split: If your home lacks the ductwork for central air or heating, you probably have a split or mini-split system instead. Split HVAC systems have internal units in each room to regulate temperature. These connect 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 use either electricity or gas for energy.
  • Heat pump: Heat pumps transfer warm and cool air between your home and the outside. These systems don't generate their own heat or AC, so they work better in more temperate climates.
  • Packaged heating and air: Packaged HVAC systems work well 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, energy-efficient, and easy to maintain.

HVAC maintenance prices vary based on the services needed. HVAC systems are complicated and may need a number of types of maintenance. Costs 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

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

  • Keep your system clean. Keeping your condenser fan blades, ductwork, grills, and indoor evaporator coil clean enables your HVAC system to function properly and lowers your risk of mold. The National Air Duct Cleaners Association recommends cleaning your home's HVAC when you notice things starting to get dirty.
  • Change filters regularly. Cleaning or replacing your air filters every 30–90 days helps air flow efficiently through your system. Also try to keep debris away from the outdoor portions of your HVAC system as much as possible.
  • 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. During winter, leaving your blinds open allows your home to benefit from passive solar heating. In the summer, keeping your blinds shut helps to block out heat. Doing both reduces the amount of work your HVAC system must perform.
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 ensure your system provides reliable air conditioning and heating for your home.

Compare Multiple Bids

Contact at least three HVAC contractors for quotes. Describe your issues and schedule an in-person inspection if possible. Compare providers' diagnoses, suggested repairs, estimated costs, warranties, and timeframes. Avoid companies that pressure you or demand upfront payment.

Check Credentials

Look for an HVAC company that employs skilled technicians with the necessary licensure and training. 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." Contractors 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 by the state.

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 an Oil Burning Equipment Installer or High Pressure Boiler Operating Engineer 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 check a company's reviews and complaints on sites such as the Better Business Bureau (BBB), Google Reviews, and Yelp. Pick a company with glowing feedback and good customer testimonials.

Understand Work Details

Always make sure you understand what a company’s process looks like. When getting HVAC repairs, ask your provider to explain which parts require replacement and why. Confirm that your technician will clean and test the system afterward to ensure proper operation. When replacing your HVAC, ask the contractor to provide details on the new energy efficiency, estimated installation time, features, model, and brand. Before signing a contract, make sure you understand the process your provider will use to select the correctly sized system for your home and what the cost will be.

Compare Warranties

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

Get Quote in Writing

Get a written quote before HVAC work starts. A comprehensive 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 Sayville, NY

You should have your HVAC system inspected approximately twice a year. At the time of the inspection, your technician will tell you what services are needed. You should also schedule an inspection 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.

Generally, it's a good idea 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 making it easier 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 a time. You may also consider a smart thermostat.

Generally, whole-system HVAC installation or replacement takes between one and three days. Installing or replacing a furnace or air conditioning unit can take as little as half a day or as much as two days. The exact amount of time will be based on factors like the size of your home, how easily accessible different sections are, and whether your technician discovers any problems.

Your HVAC company might provide financing options through a third-party lender, or you may choose 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 ductwork clean, and clean or change 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 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 HVAC system, explore Energy Star-certified or similar environmentally friendly options.
