Signs You May Need HVAC Repair or Replacement

If your home's HVAC system is malfunctioning or suffering from a lot of wear and tear, you may need to hire an HVAC contractor for maintenance or replacement. Watch for these common indicators that your system needs professional attention:

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

If you notice any of these HVAC red flags, your system evaluated. A local technician can complete an inspection, diagnose problems, and advise you whether you should repair or replace your HVAC unit.

Cost of HVAC Installation and Maintenance in Seymour

Your HVAC installation or maintenance cost varies depending on the style of unit. Common HVAC unit types include the following:

  • Split or mini-split: If your home's ductwork can't accommodate a central HVAC system, you probably have a split or mini-split system. Split systems have interior units in each room to control 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 advantage of being able to utilize either electricity or gas for power.
  • Heat pump: Heat pumps transfer hot and cold air between your house and the outdoors. They don't generate their own heating and cooling, so they work more effectively in more temperate climates.
  • Packaged heating and air: Packaged HVAC systems work best in smaller houses. They consist of a single combined heating and air conditioning unit, commonly located in a basement or attic. This unit is typically space-saving, energy-efficient, and straightforward to maintain.

HVAC maintenance costs differ based on the specific services required. HVAC systems can be complicated and potentially require a number of services. Costs for typical jobs are as follows:

HVAC Unit TypeCost
Split$1,930-$4,921
Hybrid Split$3,911-$7,206
Heat Pump$3,029-$30,860
Packaged Heating and Air$253-$422

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.

  • Keep your system clean. Keeping your condenser fan blades, ductwork, indoor evaporator coil, and grills clean helps your system run 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.
  • 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 some heat from getting inside. Doing both helps decrease the strain on your HVAC system.
  • 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 out of hand.
  • Change filters regularly. Changing 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 outside areas of your system.
ServiceCost
Filter Replacement$63-$169
Condensor Cleaning$1,267-$3,801
Thermostat Repair$84-$211
Ductwork Cleaning$405-$1,014

How To Choose a Local HVAC Company

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

Compare Multiple Bids

Contact at least three HVAC providers for quotes. Explain the issues and have specialists visit to inspect your system if possible. Compare the companies' explanations, solutions, estimated costs, warranties, and timeframes. Avoid contractors that pressure you or demand payment upfront.

Check Credentials

When looking for an HVAC company, choose one with technicians that have the right training, licenses, and experience. 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 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 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 must 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. You should also check a provider's reviews and complaints with organizations such as the Better Business Bureau (BBB), Yelp, and Google Reviews. Look for a a company with glowing reviews and stories of positive service experiences.

Understand Work Details

Always make sure you understand the details of a planned project. For HVAC repairs, your provider should detail which parts require replacement and why. Confirm that your technician will clean and test your system after repairs are done to verify that it’s working properly. When replacing your HVAC, ask the installation company to provide details on the new features, model, estimated installation time, brand, and energy efficiency. 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

Trustworthy HVAC companies stand behind their work with warranties. Compare warranties from different companies, while remembering that broader coverage is better. Look for the provider that offers the most coverage for a reasonable price.

Get Quote in Writing

Always get HVAC bids in writing before work begins. A detailed quote covers costs for both materials and labor. Ensure that you agree to all terms before signing the contract.

Frequently Asked Questions About HVAC in Seymour, CT

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

The best times to have an HVAC inspection are during 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 sees 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 is comfortable, and avoid making drastic changes — adjust it only a few degrees at once. You may also consider installing a smart thermostat.

Generally, HVAC installation or replacement takes one to 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 vary depending on things like the size of your house, how easily accessible different parts of the system are, and whether your technician runs into any problems.

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

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 offer these options, you might consider taking out your own loan. Be sure to talk to your HVAC company and a financial advisor to determine what options are available and appropriate for your situation.
