Signs You May Need HVAC Repair or Replacement

A malfunctioning or aging HVAC system probably needs professional attention from a technician who can make fixes or install a new unit. Look out for these common indicators that your HVAC needs service:

  • Unusually high energy bills
  • Rust, cracking, or corrosion
  • Refrigerant leaks
  • Strange noises when the system turns on
  • Uneven heating/cooling or poor air circulation
  • Frequent breakdowns and need for repairs
  • Thermostat malfunctions or temperature control issues
  • 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, identify problems, and advise you whether you should repair or replace your HVAC unit.

Cost of HVAC Installation and Maintenance in New Canaan

HVAC installation or maintenance costs 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 likely 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 performs similarly to a standard split system, but is able to utilize either gas or electricity as energy sources.
  • Heat pump: Heat pumps exchange hot and cool air between your home and the outdoors. They don't produce their own heat or AC, so they perform best in temperate climates.
  • Packaged heating and air: Packaged HVAC systems are a great choice for smaller homes. They have a single cooling and heating unit, normally in a basement or attic. This unit is often compact, energy-efficient, and easy to maintain.

The amount you spend on HVAC maintenance also depends on the kind of work you're having done. HVAC systems are complicated and might require different kinds of maintenance. The prices of some 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

It's important to repair or replace your HVAC system when it's broken, but it can also be expensive. Fortunately, there are some steps you can take to reduce wear and tear on your system.

  • Monitor for potential problems. Monitor your system for issues, for example by consistently checking your thermostat and energy bills. This enables you to address problems before they get out of hand.
  • Change filters regularly. Replacing 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.
  • Keep your system clean. Regularly cleaning grills, ductwork, condenser fan blades, and indoor evaporator coil helps your HVAC system run efficiently and lowers the risk of mold. The National Air Duct Cleaners Association advises cleaning your heating and cooling system when it starts to look dirty.
  • Change the position of your blinds seasonally. Opening your blinds in winter allows passive solar heat into your house. Closing your blinds in summer blocks some heat from getting indoors. Both of these measures help lower the work required from your HVAC 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

Finding the right HVAC company is key for a successful installation or repair. Hiring an experienced, credentialed HVAC contractor gives you confidence your system can provide consistent heating and air conditioning year-round.

Compare Multiple Bids

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

Check Credentials

Look for an HVAC company that employs skilled technicians who have 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 mandatory for all technicians 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 in Connecticut who work on HVAC systems 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 related to education and work experience. You should also check a provider's reviews and complaints with organizations such as the Better Business Bureau (BBB), Google Reviews, and Yelp. You'll want to select a provider with glowing reviews and stories of positive service experiences.

Understand Work Details

Always make sure you understand the details of a planned project. When HVAC repairs are required, your provider should list which parts need replacement and why. Confirm that your technician will clean and test your system after repairs are completed to ensure that it’s working properly. When replacing your HVAC, request that the installation company describe the new model, brand, estimated installation time, features, and energy efficiency. Before work starts, ask about the process your provider will use to properly size the new system for your home and how much it will cost.

Compare Warranties

A trustworthy HVAC company will stand behind its repair work and equipment installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully review warranty terms for each contractor and choose the company that provides the greatest protection within your budget.

Get Quote in Writing

Always get HVAC bids in writing before work begins. A thorough quote will cover costs for both materials and labor. Confirm that you understand all terms before signing the contract.

Frequently Asked Questions About HVAC in New Canaan, CT

You should have your HVAC system inspected about twice yearly. After the inspection, your technician will inform you if any services are needed. You should also schedule an inspection if you start noticing issues such as unusual smells, strange noises, or leaks. If your system has ductwork, you should have it inspected every few years.

Generally, it's a good idea to schedule inspections in the spring and fall, as technicians tend to be less busy at these times. This also helps get your system ready for the summer and winter, when it likely 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. During all seasons, 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 may also consider a smart thermostat.

It takes roughly one to three days to have an HVAC system installed or replaced. If you only need an air conditioning unit or a furnace, this can take between half a day and two days. This timeline will be influenced by the size of your house, the accessibility of your system, and any issues your technician uncovers.

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 to purchase an air conditioning unit with around 2.5 to 5 tons of capacity. Generally, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.

Typically, HVAC financing is provided by a third-party lender. If your HVAC company doesn't offer financing, you may consider taking out your own loan. Be sure to talk to your HVAC company and a financial advisor to learn what options are available to you and appropriate for your situation.

There are several ways you can make your HVAC system more energy-efficient:

  • Make sure your air ducts remain clean, and change or clean your air filters regularly.
  • Have regular inspections to take care of issues as they arise.
  • Keep your attic well-ventilated and make sure all doors and windows are well-sealed.
  • Install a smart thermostat. If you don't want to or can't buy 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 system, see if there are Energy Star-certified or similar environmentally friendly options.
