Signs You May Need HVAC Repair or Replacement

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

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

These HVAC red flags indicate that you should have your system evaluated. A local provider 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 East Lyme

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

  • Split or mini-split: If your home's ductwork can't accommodate a central HVAC system, you likely 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 unit operates similarly to a regular split system. It provides flexibility by having the option to use either electricity or gas for energy.
  • Heat pump: Heat pumps transfer warm and cold air between your home and the outdoors. They don't make their own heat or AC, so they work best in moderate climates.
  • Packaged heating and air: Packaged HVAC systems are a smart choice for smaller houses. They have a single heating and cooling unit, usually in a basement or attic. This unit is often small, cost-effective, and easy to maintain.

HVAC maintenance prices differ depending on the particular service needed. HVAC systems are complicated and might require different maintenance services. Costs for common services are as follows:

HVAC Unit TypeCost
Split$1,871-$4,769
Hybrid Split$3,791-$6,984
Heat Pump$2,935-$29,908
Packaged Heating and Air$246-$409

Ways to Save Money on HVAC Costs

It’s important to take care of HVAC repairs and replacements when they are required, though they can be expensive. The good news is that homeowners have ways to minimize progressive deterioration and reduce the frequency of breakdowns.

  • Change the position of your blinds seasonally. Keeping your blinds closed in the summer helps block out passive solar heat. Keeping them open in the winter helps you take advantage of this same heat. Both of these measures help reduce the amount of work your HVAC system needs 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.
  • Change filters regularly. Switching out your air filters or washing them every 1–3 months allows effective air circulation through your system. Also try to keep debris from accumulating on the outdoor sections of your HVAC.
  • Monitor for potential problems. Keep an eye on your system for issues, for example by consistently checking your thermostat and energy bills. This helps you address problems before they get too expensive.
ServiceCost
Filter Replacement$61-$164
Condensor Cleaning$1,228-$3,684
Thermostat Repair$82-$205
Ductwork Cleaning$393-$982

How To Choose a Local HVAC Company

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

Compare Multiple Bids

Get quotes from at least three HVAC providers. Explain your issues and ask if technicians can inspect your system in person. Compare each company's diagnoses, recommended solutions, estimated cost, timelines, and warranties. Avoid contractors that pressure you or demand payment before work.

Check Credentials

When hiring an HVAC provider, 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 required for any individual who helps "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 at the state level.

All individuals who work on HVAC systems in Connecticut need to be licensed by the Connecticut State Department of Consumer Protection. A worker can be licensed as a journeyperson or a contractor. Both license types have requirements related to education and work experience. Always check a company's reviews and complaints with organizations such as Yelp, Google Reviews, and the Better Business Bureau (BBB). Look for a a provider with positive reviews and a history of good customer service.

Understand Work Details

Make sure you know the details of your project before it begins. When getting HVAC repairs, have your provider list which parts need replacement and why. Get confirmation that your technician will clean and test the system after the repair to ensure that everything works. When replacing your HVAC, have the contractor explain the new energy efficiency, model, features, estimated installation time, and brand. Before signing a contract, 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

A reputable HVAC company will back its repair services and equipment installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully compare the fine print between contractors and choose the company that provides the greatest protection at a reasonable price.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in East Lyme, CT

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

The best times of the year to have an HVAC inspection are the spring and fall. Technicians tend to be less busy during these times, so it will be easier to get an appointment. This also helps get your system ready for the summer and winter, the times of the year when it gets the most use.

You can save energy throughout the year by making it easier for your HVAC system to maintain your home's temperature. Always keep your thermostat as close to the outside temperature as is comfortable, and try to adjust it only a few degrees at once. You might also consider a smart thermostat.

Generally, whole-system HVAC installation or replacement takes one to three days. Installing or replacing a furnace or air conditioning unit can take as little as half a day or as much as two days. The exact amount of time will depend on things like the size of your house, how easily accessible different sections are, and whether your technician finds any problems.

For a 2,000-square-foot home, you'll need between 2.5 and 5 tons of air conditioning capacity. For homes over 1,000 square feet, central air will 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).

Usually, HVAC financing is offered through a third-party lender. If your HVAC company doesn't have financing options, you might consider taking out your own loan. Be sure to speak with your HVAC company and a financial advisor to learn 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:

  • Make sure your air ducts remain clean, and change or clean your air filters regularly.
  • Have 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 the temperature indoors 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 other environmentally friendly options.
