Signs You May Need HVAC Repair or Replacement

An HVAC system that's not working properly or past its lifespan likely needs professional attention for repairs or replacement. Watch for these signals that your system needs service:

  • Refrigerant leaks
  • Odd noises when turning on
  • Frequent breakdowns and need for repairs
  • Corrosion, rust, or cracking
  • Unusually high energy bills
  • Temperature control issues or thermostat malfunctions
  • Uneven heating/cooling or poor air circulation
  • 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, identify problems, and decide whether you need repairs or a new HVAC unit.

Cost of HVAC Installation and Maintenance in Lake Grove

HVAC installation or maintenance prices vary depending on your system. 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 works almost the same as a standard split system. It has the benefit of having the capability to use either gas or electricity for power.
  • Heat pump: Heat pumps move warm and cool air between your home and outside. They don't make their own heating and cooling, so they work more efficiently in more mild climates.
  • Packaged heating and air: Packaged HVAC systems work best in smaller houses. They consist of a single combined heating and air conditioning unit, typically located in a basement or attic. This unit is typically space-saving, cost-effective, and straightforward to maintain.

The cost of HVAC maintenance also varies depending on the kind of work being done. HVAC systems are complicated and can require different kinds of maintenance. The cost of some common repairs is 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. Luckily, there are steps homeowners can take to reduce wear and tear on their HVAC and lower future maintenance needs.

  • Monitor for potential problems. Keeping an eye out for problems, for instance by routinely checking your thermostat and energy bills, helps you resolve them before they get too expensive.
  • Change filters regularly. Air flows through your HVAC system most effectively when you replace or clean the filters every 1–3 months. Also avoid letting debris pile up on the outside areas of your HVAC.
  • 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 decreases the amount of work your HVAC system is required to do.
  • Keep your system clean. Keeping your grills, condenser fan blades, ductwork, and indoor evaporator coil clean helps your system function optimally and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends that you clean your HVAC system when it starts to look dirty.
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 crucial for a smooth installation or repair. An experienced, credentialed HVAC contractor gives you confidence your system can provide consistent heating and air conditioning year-round.

Compare Multiple Bids

Request estimates from three or more HVAC companies. Explain your issues and ask if specialists can inspect your system in person. Compare each provider's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid providers that pressure you or demand payment before work.

Check Credentials

Choose an HVAC company with skilled technicians who have proper licensing and experience. In all states, HVAC contractors have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, an individual must pass an exam (the type of 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 at the state level.

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 check reviews and complaints on sites like Google Reviews, Yelp, and the Better Business Bureau (BBB). Pick a company with glowing reviews and reports of great customer experiences.

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 need replacement and why. Get confirmation that your technician will clean and test your system after the repair to ensure that everything works. When replacing your HVAC, have the contractor explain the new brand, features, model, estimated installation time, and energy efficiency. Before signing a contract, be sure you understand the process your provider will use to size the new HVAC system appropriately for your home and what the price will be.

Compare Warranties

Trustworthy HVAC companies back their work with warranties. Look at warranties from different companies, remembering that broader coverage is better. Look for the company that offers the most coverage for a fair price.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Lake Grove, NY

You should have your HVAC system inspected twice annually. After completing their inspection, your technician will inform you what services are needed. You should also have your system inspected if you start noticing issues such as strange noises, leaks, or unusual smells. 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 these times tend to be less busy. 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 possible, and try to adjust it only a few degrees at a time. You may also consider installing a smart thermostat.

Generally, whole-system HVAC installation or replacement takes between one and three days. 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 the size of your house, how easily accessible different sections are, and whether your technician discovers any problems.

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

For a 2,000-square-foot home, you'll also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units).

Typically, HVAC financing is offered through a third-party lender. If your HVAC company doesn't have financing options, you could consider taking out a loan on your own. Be sure to speak with a financial advisor and your HVAC company to find out what options are available to you and appropriate for your situation.

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.
  • 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 your inside temperature as close to the outside temperature as you can.
  • When it comes time to replace any part of your system, explore Energy Star-certified or similar environmentally friendly options.
