Signs You May Need HVAC Repair or Replacement

If your HVAC system is faulty or getting near the end of its lifespan, it likely needs servicing or replacement from an HVAC company. Watch for these indicators your system needs service:

  • Poor air circulation or uneven heating/cooling
  • Refrigerant leaks
  • Strange noises when the system turns on
  • Thermostat malfunctions or temperature control issues
  • Corrosion, rust, or cracking
  • Higher than normal energy bills
  • Frequent breakdowns and need for repairs
  • 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 figure out whether you need to fix or replace your HVAC.

Cost of HVAC Installation and Maintenance in Fairfield

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

  • Split or mini-split: If your home lacks the right ductwork for central heating or air, you probably have a split HVAC system. Split or mini-split systems consist of interior units that regulate the temperature in individual rooms, and that are all connected to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions very similarly to a standard split system. It has the benefit of being able to utilize either gas or electricity for power.
  • Heat pump: Heat pumps circulate hot and cool air between your home and the outdoors. They don't generate their own heat or AC, so they perform best in mild climates.
  • Packaged heating and air: Packaged HVAC systems are a smart choice for smaller homes. These systems have a single heating and cooling unit, normally located in a basement or attic. They're small, cost-effective, and easy to maintain.

HVAC maintenance prices vary based on the work 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$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

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

  • Change filters regularly. Changing or cleaning your air filters every 30–90 days helps air flow smoothly through your HVAC system. We also recommend regularly clearing dirt and debris away from the external parts of your system.
  • Change the position of your blinds seasonally. Leaving your blinds open during the winter helps warm your home with passive solar heating. Closing the blinds in warmer seasons helps prevent the heat from getting inside. Doing both helps minimize the demand on your HVAC system.
  • Keep your system clean. Keeping your indoor evaporator coil, condenser fan blades, grills, and ductwork clean helps your system function optimally and reduces the chance of mold growth. The National Air Duct Cleaners Association recommends that you clean your HVAC system whenever it begins to look dirty.
  • Monitor for potential problems. Monitoring your system for problems — for example, by checking your thermostat and energy bills routinely — helps you get ahead of problems before they get too expensive.
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 keep your system running efficiently, providing you with effective heating and cooling 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 training and licenses. In all states, HVAC contractors need to 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." An individual 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 by the state.

All individuals who work on HVAC systems in Connecticut need 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. Always check a company's reviews and complaints with organizations such as Google Reviews, the Better Business Bureau (BBB), and Yelp. You want to hire a provider with positive reviews and a history of good customer service.

Understand Work Details

Always make sure you understand what a company’s process looks like. When HVAC repairs are needed, ask your provider to explain which parts need replacement and explain why. Confirm that your technician will clean and test the system after finishing the work to ensure proper operation. When replacing your HVAC, ask the provider to explain the new brand, features, estimated installation time, energy efficiency, and model. Before signing paperwork, make 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

Reliable HVAC companies provide warranties for their services. Broader coverage is better, so make sure to compare warranties between companies. Choose the one that offers the best coverage at a reasonable cost.

Get Quote in Writing

Get written bids before beginning any HVAC work. The quote should include costs for both materials and labor. Review all terms carefully before signing.

Frequently Asked Questions About HVAC in Fairfield, CT

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

The best times of the year to have your HVAC system inspected are the spring and fall. Technicians are 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, when it typically 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 your home's temperature. Always keep your thermostat as close to the outside temperature as you can, and try to adjust it only a few degrees at a time. You could also consider purchasing 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 takes anywhere from about half a day up to two days. The exact amount of time will depend on factors like how large your home is, how easily accessible different parts of the system are, and whether your technician finds any problems.

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

Your HVAC company might provide financing options through a third-party lender, or you might choose to obtain a loan on your own. It's a good idea to discuss payment options with your HVAC company and a financial advisor to make sure that you find the best option for you.
