Signs You May Need HVAC Repair or Replacement

An HVAC system that's malfunctioning or outdated likely needs professional attention for repairs or replacement. Watch for these signals that your system needs service:

  • Frequent breakdowns and need for repairs
  • Rust, corrosion, or cracking
  • Temperature control issues or thermostat malfunctions
  • Strange noises when the system turns on
  • Refrigerant leaks
  • Unusually high energy bills
  • Uneven heating/cooling or poor air circulation
  • 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 recommend repairing or replacing your HVAC unit.

Cost of HVAC Installation and Maintenance in Windsor

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: If your home doesn't have the right ductwork for central air or heating, you probably have a split HVAC system. Split or mini-split systems consist of indoor units that control the temperature in individual rooms, and that are all connected 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 work by transferring warm and cool air between your home and the outdoors. These systems don't produce heat or air conditioning themselves, and are better for more moderate climates.
  • Packaged heating and air: Packaged HVAC systems are a smart choice for smaller homes. They have a single heating and cooling unit, normally in an attic or basement. This unit is often small, energy-efficient, and easy to maintain.

HVAC costs differ 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$1,995-$5,086
Hybrid Split$4,043-$7,448
Heat Pump$3,130-$31,897
Packaged Heating and Air$262-$437

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. Luckily, there are some steps you can take to slow the wear and tear on your system.

  • Change filters regularly. Cleaning or replacing your air filters every 30–90 days helps air flow smoothly through your system. Also try to keep debris away from the outdoor portions of your HVAC system as much as possible.
  • 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 strain on your HVAC system.
  • Keep your system clean. Keeping your grills, ductwork, condenser fan blades, and indoor evaporator coil clean enables your HVAC system to function properly and lowers your risk of mold. The National Air Duct Cleaners Association suggests cleaning your HVAC system when you notice it starting to get dirty.
  • Monitor for potential problems. Monitoring the efficiency of your HVAC system — for instance by reviewing your thermostat settings and energy bills — helps you identify and fix problems before they get out of hand.
ServiceCost
Filter Replacement$65-$175
Condensor Cleaning$1,310-$3,929
Thermostat Repair$87-$218
Ductwork Cleaning$419-$1,048

How To Choose a Local HVAC Company

Knowing what makes a trustworthy HVAC company is key for a smooth installation or repair. 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 providers for quotes. Describe the issues and have specialists visit to inspect your HVAC system if possible. Compare the contractors' explanations, solutions, estimated costs, timeframes, and warranties. Avoid contractors that pressure you or demand payment upfront.

Check Credentials

Look for an HVAC company that employs skilled technicians who have the necessary licensure and training. 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 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 must be licensed by the Connecticut State Department of Consumer Protection. An individual can be licensed as a journeyperson or a contractor. Both license types have requirements related to education and work experience. Always check a provider's reviews and complaints with organizations such as Yelp, the Better Business Bureau (BBB), and Google Reviews. Look for a a company with positive reviews and a history of good customer service.

Understand Work Details

It’s important to understand what the work process will look like. For HVAC repairs, the company should explain the specific parts that need replacement and why. Get confirmation that your technician will clean and test the full system afterward to ensure proper functioning. When replacing your HVAC, have the provider describe the new features, energy efficiency, brand, model, and estimated installation time. Before signing a contract, ask how your provider plans to accurately size the unit for your home and how much it will cost.

Compare Warranties

Reputable HVAC companies stand behind their work with warranties. Compare warranties from different companies, while remembering that more comprehensive coverage is better. Look for the company that offers the most coverage for a reasonable price.

Get Quote in Writing

Always get quotes for HVAC service in writing before committing to a provider. An itemized quote should cover both labor and materials. Make sure you agree to all terms before signing a contract.

Frequently Asked Questions About HVAC in Windsor, CT

Typically, you should have your HVAC system inspected twice a year. After that inspection, your HVAC technician will tell you what, if any, services are needed. You should also have an inspection 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 your HVAC system inspected 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 helps get your system 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 may also consider installing a smart thermostat.

It takes between one and three days to have your HVAC system installed or replaced. If you only need a furnace or a single air conditioning unit, this might take between half a day and two days. This timeline can be influenced by the size of your house, the accessibility of your system, and any new 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 look for an air conditioning unit with between 2.5 and 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.

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

  • Make sure your air ducts remain clean, and clean or change your air filters on a regular basis.
  • Have regular inspections to take care of problems 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 to keep your inside temperature as close to the outside temperature as you can.
  • When replacing part of your system, explore Energy Star-certified or similar environmentally friendly options.
