Signs You May Need HVAC Repair or Replacement

If your HVAC system is faulty or getting near the end of its lifespan, it likely needs repairs or replacement from an HVAC company. Watch for these signs your system needs service:

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

If you notice any of these HVAC red flags, your system evaluated. A local company 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 Glastonbury

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'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 control temperature. These indoor units all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system operates similar to a normal split system, but has the benefit of being able to draw power from either gas or electric sources.
  • Heat pump: Heat pumps exchange warm and cool air between your house and the outdoors. They don't generate their own heating and cooling, so they work more efficiently in more moderate climates.
  • Packaged heating and air: Packaged HVAC systems work well in smaller houses. They consist of a single combined heating and air conditioning unit, typically located in a basement or attic. This unit is typically compact, energy-efficient, and straightforward to maintain.

HVAC maintenance prices vary depending on the particular service needed. HVAC systems are complex and might require different kinds of maintenance. Fees for common services 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

Repairing or replacing your HVAC system when needed is important, but can be costly. Fortunately, there are actions you can take to minimize wear and tear over time on your system.

  • 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 frequency with which you need to run your HVAC.
  • 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 outside areas of your system.
  • Monitor for potential problems. Keeping a close eye on the efficiency of your HVAC system — for instance by reviewing your thermostat settings and energy bills — helps you find and solve issues before they get too expensive.
  • Keep your system clean. Cleaning your indoor evaporator coil, condenser fan blades, ductwork, and grills regularly helps keep your HVAC system working efficiently and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it begins to look dirty.
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 the right things to look for in an HVAC company is key for a smooth installation or repair. 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 contractors for quotes. Describe your issues and schedule an in-person inspection if possible. Compare companies' 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 must 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 on a state-by-state basis.

All individuals in Connecticut who work on HVAC systems need 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 reviews and complaints on sites like Yelp, Google Reviews, and the Better Business Bureau (BBB). Choose a company with glowing reviews and reports of great customer experiences.

Understand Work Details

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

Reputable HVAC companies stand behind their work with warranties. Look at warranties from different companies, remembering that more comprehensive coverage is better. Look for the provider that offers the most coverage for a fair price.

Get Quote in Writing

Always get HVAC estimates in writing before work begins. A thorough quote covers costs for both materials and labor. Ensure that you understand all terms before signing the contract.

Frequently Asked Questions About HVAC in Glastonbury, CT

Normally, 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 strange noises, unusual smells, or leaks. If you have ductwork in your home, 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 often 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. During all seasons, keep your thermostat as close to the outside temperature as possible, and try to adjust it only a few degrees at a time. You could also consider a smart thermostat.

It takes roughly one to three days to have an HVAC system installed or replaced. If you only need a furnace or a single air conditioning unit, this can take anywhere from a few hours up to two days. This timeline will be influenced by the size of your home, how easily accessible your system is, and any new issues your technician uncovers.

For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. For homes over 1,000 square feet, central air will usually 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).

There are a number of ways you can make your HVAC system more energy-efficient:

  • Keep ductwork clean, and change or clean 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 the temperature indoors as close to the outside temperature as is comfortable.
  • When replacing part of your system, explore Energy Star-certified or other environmentally friendly options.
