Signs You May Need HVAC Repair or Replacement

An HVAC system that's broken or old likely needs professional attention for maintenance or replacement. Watch for these signals that your system needs service:

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

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

Cost of HVAC Installation and Maintenance in Mount Sinai

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

  • Split or mini-split: If your home doesn’t have the ductwork for central air or heating, you likely have a split or mini-split system instead. Split HVAC systems have internal units in each room to control temperature. These connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions in the same way as a normal split system, but has the benefit of being able to draw power from either gas or electric sources.
  • Heat pump: Heat pumps move hot and cold air between your house and the outdoors. They don't create their own heating and cooling, so they work more effectively in more temperate climates.
  • Packaged heating and air: Packaged HVAC systems work well in smaller homes. They consist of a single combined air conditioner and heating unit, commonly located in a basement or attic. This unit is typically small, energy-efficient, and easy to maintain.

HVAC maintenance prices differ depending on the particular service needed. HVAC systems are complex and might require different kinds of maintenance. Costs for common services 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 make any essential HVAC fixes or replacements as needed, though they can be expensive. The good news is that homeowners have ways to reduce gradual wear and tear and reduce the frequency of breakdowns.

  • Change the position of your blinds seasonally. Keeping your blinds open in the winter helps you take advantage of passive solar heating. Keeping them closed in the summer helps keep some of this heat out. Both of these measures help reduce the amount of work your HVAC system needs to do.
  • Keep your system clean. Cleaning your grills, ductwork, indoor evaporator coil, and condenser fan blades regularly helps your HVAC system work efficiently and lowers the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.
  • Change filters regularly. Cleaning or replacing your air filters every 1–3 months helps air flow smoothly through your system. You should also try to keep debris away from the outdoor portions of your HVAC system as much as possible.
  • Monitor for potential problems. Monitoring your system for problems — for example, by checking your thermostat and energy bills routinely — helps you catch 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

Knowing what to look for in an HVAC company is important for a successful project. Look for an experienced, licensed contractor that can give you peace of mind and make sure your system provides reliable air conditioning and heating for your home.

Compare Multiple Bids

Get quotes from at least three HVAC providers. Explain your issues and ask if specialists can inspect your system in person. Compare each contractor's diagnoses, recommended solutions, estimated cost, warranties, and timelines. Avoid contractors that pressure you or demand payment before work.

Check Credentials

When picking an HVAC provider, choose one with technicians that have the proper training, licenses, and experience. HVAC contractors in all states need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for all technicians 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 what kind of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled at the state level.

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. Checking reviews on Google Reviews, the Better Business Bureau (BBB), Yelp, and similar sites can help your decision as well. Choose a provider with great reviews and reports of positive experiences from customers.

Understand Work Details

Always make sure you understand the details of your project. When HVAC repairs are required, your provider should list which parts require replacement and why. Confirm that your technician will clean and test your system after repairs are done to ensure that it’s working properly. When getting a replacement, ask your contractor to explain the new HVAC system estimated installation time, energy efficiency, model, brand, and features. Before signing a contract, you should understand how your provider will size the system appropriately for your home and the price you'll pay.

Compare Warranties

Reliable HVAC companies provide warranties for their work. The broader the coverage, the better, so make sure to review warranties between companies. Choose the one that provides the most comprehensive coverage at a fair cost.

Get Quote in Writing

Always get estimates for HVAC service in writing before committing to a provider. A detailed quote should cover both labor and materials. Make sure you understand all terms before signing a contract.

Frequently Asked Questions About HVAC in Mount Sinai, NY

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

The best times to have your HVAC system inspected are the spring and fall. Technicians are generally less busy during these times, so it will be easier to get an appointment. This also ensures that your system is ready for the summer and winter, which is when it normally gets 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 possible, and try to adjust it only a few degrees at a time. You might also consider getting a smart thermostat.

Generally, HVAC installation or replacement takes between one and three days for the entire system. Installing or replacing an air conditioning unit or a furnace may take anywhere from a few hours up to two days. The exact amount of time will be based on factors like how large your home is, how easily accessible different areas are, and whether your technician discovers any problems.

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 look for an air conditioning unit with between 2.5 and 5 tons of capacity. In general, if your home is over 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 might be able to obtain your own loan. It's a good idea 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 change or clean your air filters on a regular basis.
  • Have regular inspections to take care of problems as they arise.
  • Make sure your doors and windows are well-sealed and keep your attic well-ventilated.
  • Install a smart thermostat. If you aren't able to purchase one, try to keep your inside temperature 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 similar environmentally friendly options.
