Signs You May Need HVAC Repair or Replacement

A malfunctioning or aging HVAC system probably needs attention from a professional who can make repairs or install a new unit. Keep an eye out for these common signs that your HVAC needs service:

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

Arrange an inspection if you notice any of these problems. A local technician can evaluate your system, detect problems, and figure out whether you need repairs or a new HVAC unit.

Cost of HVAC Installation and Maintenance in Colchester

The price of HVAC installation or maintenance varies depending on the type of unit you have. Common types of HVAC units include the following:

  • Split or mini-split: If your home lacks the right ductwork for central air or heating, you probably have a split HVAC system. Split or mini-split systems consist of internal units that control the temperature in individual rooms. These interior units are all connected to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions comparably to a regular split system. It gives flexibility by providing the option to use either electricity or gas for energy.
  • Heat pump: Heat pumps move warm and cool air between your home and outside. These systems don't produce their own heat or AC, so they work better in milder climates.
  • Packaged heating and air: Packaged HVAC systems are good for smaller homes. These systems consist of a single combined heating and cooling unit, normally located in a basement or attic. This unit tends to be compact, efficient, and easy to maintain.

The cost of HVAC maintenance also varies depending on the kind of work you're having done. HVAC systems are complex and can require different kinds of maintenance. The cost of some common repairs is 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 fix or swap out your HVAC components when they become damaged, but it can also be expensive. Fortunately, there are some steps you can take to slow the wear and tear on your HVAC.

  • Change filters regularly. Air flows through your HVAC system most effectively when you change out or clean the filters every 1–3 months. Also avoid letting debris pile up on the outside areas of your HVAC.
  • 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 home’s HVAC system.
  • Keep your system clean. Keeping your ductwork, grills, condenser fan blades, and indoor evaporator coil clean helps your HVAC system function effectively and lowers your risk of mold. The National Air Duct Cleaners Association suggests cleaning your HVAC when you notice things starting to get dirty.
  • Monitor for potential problems. Keep an eye on your system for issues, for example by routinely checking your thermostat and energy bills. This allows you to 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 the right things to look for in an HVAC company is key for a smooth repair or installation. Picking an established business with certified technicians gives you assurance your HVAC system will deliver consistent coolig and heating year-round.

Compare Multiple Bids

Contact at least three HVAC companies for quotes. Explain the issues and have technicians visit to inspect your HVAC system if possible. Compare the providers' 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 qualified 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 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 by the state.

All individuals who work on HVAC systems in Connecticut 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 for education and work experience. You should also check a company's reviews and complaints on sites such as Yelp, Google Reviews, and the Better Business Bureau (BBB). Pick a company with great feedback and good customer testimonials.

Understand Work Details

Make sure you understand the details of your project before starting. When getting HVAC repairs, have your provider detail which parts need replacement and why. Confirm that your technician will clean and test the system after the repair to verify that everything works. When replacing your HVAC, request that the company explain the new estimated installation time, brand, energy efficiency, model, and features. Before work starts, 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

Reputable HVAC companies back their services with warranties. Compare warranties from different companies, remembering that more comprehensive coverage is better. Look for the provider that offers the most coverage for a reasonable price.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Colchester, CT

You should have your HVAC system inspected about twice annually. At the time of the inspection, your technician will inform you what services are required. You should also have your system inspected if you start noticing issues such as strange noises, leaks, or unusual smells. If your system has ductwork, it should be inspected every few years.

Generally, it's smart 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 probably 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 the temperature of your home. 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 once. You may also consider installing a smart thermostat.

Generally, HVAC installation or replacement takes between one and 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 factors like the size of your home, how easily accessible different areas are, and whether your technician runs into any problems.

For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. If your home is larger than 1,000 square feet, central air will usually be more effective for cooling than window units.

For a 2,000-square-foot home, you should also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units).

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

  • Keep ductwork clean, and clean or change your air filters regularly.
  • Schedule 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 is comfortable.
  • When it comes time to replace any part of your system, explore Energy Star-certified or other environmentally friendly options.
