Signs You May Need HVAC Repair or Replacement

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

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

Schedule an inspection if you notice any of these problems. A local technician can evaluate your system, identify problems, and figure out whether you need repairs or a new HVAC unit.

Cost of HVAC Installation and Maintenance in New Fairfield

What you pay for HVAC installation or maintenance varies based on your system style. Common HVAC unit styles include the following:

  • Split or mini-split: Homes without ductwork for centralized climate control often have split or mini-split HVAC systems. These systems consist of interior units in each room to control temperature. These indoor units 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 for power.
  • Heat pump: Heat pumps transfer warm and cold air between your home and the outdoors. They don't generate their own heat or AC, so they work best in moderate climates.
  • Packaged heating and air: Packaged HVAC systems are more popular in smaller houses. Packaged systems consist of a single combined heating and cooling unit, usually located in an attic or basement. This unit tends to be efficient, compact, and easy to maintain.

HVAC maintenance prices vary based on the specific services needed. HVAC systems can be complex and potentially require several different services. Price ranges for typical jobs are as follows:

HVAC Unit TypeCost
Split$2,035-$5,189
Hybrid Split$4,124-$7,598
Heat Pump$3,193-$32,538
Packaged Heating and Air$267-$445

Ways to Save Money on HVAC Costs

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

  • Monitor for potential problems. Monitor your system for issues, for example by routinely checking your thermostat and energy bills. This allows you to address problems before they get too expensive.
  • Change the position of your blinds seasonally. Leaving your blinds open during the colder months allows passive solar heating to warm your home. Closing the blinds in warmer seasons helps prevent the same heat from getting inside. Doing both helps reduce the demand on your HVAC.
  • Keep your system clean. Keeping your indoor evaporator coil, condenser fan blades, grills, and ductwork clean helps your HVAC system function properly and lowers your risk of mold. The National Air Duct Cleaners Association suggests cleaning your home's HVAC when you notice things starting to get dirty.
  • Change filters regularly. Replacing or cleaning your air filters every 1–3 months helps air flow efficiently through your HVAC system. We also recommend regularly clearing dirt and debris away from the external parts of your system.
ServiceCost
Filter Replacement$67-$178
Condensor Cleaning$1,336-$4,008
Thermostat Repair$89-$223
Ductwork Cleaning$428-$1,069

How To Choose a Local HVAC Company

Knowing the indicators of a good HVAC company is important. Working with a contractor that's properly licensed and highly experienced will give you confidence that they can fix your system, providing you with effective air conditioning and heating for your home.

Compare Multiple Bids

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

Check Credentials

When looking for an HVAC company, choose one with technicians that have the appropriate training, licenses, and experience. HVAC contractors in all states must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required 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.

All individuals who work on HVAC systems in Connecticut are required to be licensed by the Connecticut State Department of Consumer Protection. An individual can be licensed as a journeyperson or a contractor. Both types of licenses have requirements for education and work experience. Reviewing feedback on Yelp, the Better Business Bureau (BBB), Google Reviews, and similar sites can assist your decision. Choose a company with stellar reviews and stories of positive experiences from customers.

Understand Work Details

Always make sure you know the details of any project. For HVAC repairs, your provider should specify which parts require replacement and why. Confirm that your technician will clean and test the system after repairs are completed to verify that it’s working properly. When replacing your HVAC system, ask your contractor to provide details on the new estimated installation time, features, energy efficiency, model, and brand. Before signing a contract, make sure you understand how your provider will properly size the new unit for your home and what the cost will be.

Compare Warranties

Good HVAC companies offer warranties on service and installations. The more complete the coverage, the better. Compare warranty details between companies and pick the one that offers the most comprehensive protection for the fairest price.

Get Quote in Writing

Get a written proposal before HVAC work begins. A full quote includes both labor and material costs. Make sure you understand and accept all terms before signing the contract.

Frequently Asked Questions About HVAC in New Fairfield, CT

You should have your HVAC system inspected about twice annually. Following an inspection, your technician will inform you if any services are required. You should also call a technician if you notice new issues such as strange noises, unusual smells, or leaks. If your home has ductwork, you should have it inspected every few years.

Generally, it's smart to schedule inspections 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 likely sees the most use.

You can save energy throughout the year by reducing the amount of power your HVAC system uses to maintain the temperature of your home. 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 your HVAC system installed or replaced. If you need just an air conditioning unit or a furnace, this may take anywhere from a few hours up to two days. This timeline can be determined by the size of your home, how easily accessible your system is, and any new issues your technician discovers.

For a 2,000-square-foot home, you should look for 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 an air conditioning unit with around 2.5 to 5 tons of capacity. Usually, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.

Typically, HVAC financing is offered through a third-party lender. If your HVAC company doesn't offer financing, you may consider taking out a loan on your own. 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 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 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 keeping your inside temperature as close to the outside temperature as is comfortable.
  • When it comes time to replace any part of your HVAC system, explore Energy Star-certified or similar environmentally friendly options.
