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. Look for these indicators your system needs service:

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

If you see any of these HVAC issues, have a technician inspect your system. A local professional can identify problems and decide whether fixing or replacing your HVAC unit is the correct solution.

Cost of HVAC Installation and Maintenance in Ontario

The price of HVAC installation or maintenance changes depending on the kind of unit you have. Common varieties of HVAC units 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 internal units in each room to control temperature. These indoor units all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions comparably to a regular split system. It gives flexibility by having the option to draw on either electricity or gas for energy.
  • Heat pump: Heat pumps work by circulating hot and cold air between your home and the outdoors. These systems don't generate heat or air conditioning themselves, and are more suited to more moderate climates. They may not be as effective during Ontario's hot summers.
  • Packaged heating and air: Packaged HVAC systems are a good choice for smaller homes. These systems have a single heating and cooling unit, typically located in a basement or attic. They're compact, cost-effective, and easy to maintain.

The cost of HVAC maintenance also varies depending on the kind of work being done. HVAC systems are complex and may require different kinds of maintenance. The cost of some common repairs is as follows:

HVAC Unit TypeCost
Split$1,890-$4,817
Hybrid Split$3,829-$7,054
Heat Pump$2,965-$30,211
Packaged Heating and Air$248-$414

Ways to Save Money on HVAC Costs

It’s important to complete repairs or full-system HVAC replacements as needed, 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. During winter, leaving your blinds open allows your home to benefit from passive solar heating. In the summer, keeping your blinds shut helps to block out heat. Doing both helps minimize the amount of work your HVAC system is required to do.
  • Change filters regularly. Air flows best through your HVAC system when you change out or clean the filters every 1–3 months. Also try not to let debris pile up on the external sections of your HVAC.
  • Keep your system clean. Regularly cleaning condenser fan blades, indoor evaporator coil, grills, and ductwork helps keep your HVAC system running efficiently and lowers your risk of mold. The National Air Duct Cleaners Association recommends cleaning your heating and cooling system when it starts to look 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$62-$165
Condensor Cleaning$1,241-$3,722
Thermostat Repair$83-$207
Ductwork Cleaning$397-$992

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. Established providers with certified technicians can offer assurance your HVAC system will deliver consistent coolig and heating year-round.

Compare Multiple Bids

Contact at least three HVAC providers 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 companies that pressure you or demand payment upfront.

Check Credentials

It's important to choose an HVAC company that employs technicians with the proper qualifications and expertise. In all states, HVAC contractors have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, contractors must pass an exam (the specific exam depends on what kind of equipment they plan to work with). Section 608 certification is required for all technicians who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." All other licensing requirements are handled on a state-by-state basis.

HVAC contractors in California must be licensed by the Department of Consumer Affairs Contractors State License Board (CSLB). HVAC contractors are considered specialty contractors by the CSLB. All contractors are required to have four years of experience and to be bonded, and contractors with employees must also meet insurance requirements. Also check a company's reviews and complaints on sites such as Google Reviews, the Better Business Bureau (BBB), and Yelp. Pick a company with great feedback and good customer testimonials.

Understand Work Details

Make sure you know the details of any project before it begins. When getting HVAC repairs, have your provider list which parts require replacement and why. Confirm that your technician will clean and test the entire system after the repair to ensure that everything works. When replacing your HVAC, request that the company explain the new features, model, brand, estimated installation time, and energy efficiency. Before signing a contract, be 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. Look at warranties from different companies, bearing in mind that broader coverage is better. Look for the company that provides the most coverage for a fair price.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Ontario, CA

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

The best times to have your HVAC system inspected are the spring and fall. Technicians tend to be less busy during these times, which makes it 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 during the summer by making it easier for your HVAC system to keep your home cool. Set your thermostat as close to the outside temperature as you comfortably can, and avoid making drastic changes in temperature all at once. Keep your roof well-maintained and seal any leaks around your doors and windows to avoid letting cool air escape. Similarly, ensure that your attic is well ventilated to avoid trapping excess heat in your home.

Generally, HVAC installation or replacement takes one to three days for the entire system. 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 be based on factors like how large your home is, how easily accessible different areas are, and whether your technician discovers any problems.

For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. In Ontario, you'll probably want to purchase a unit on the higher end of this range. If your home is larger than 1,000 square feet, central air will generally 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). In Ontario, you might be able to make do with a lower-capacity furnace.

Your HVAC company might provide financing options through a third-party lender, or you might choose to obtain your own loan. It's a good idea to discuss payment options with your HVAC company and a financial advisor to make sure that you find the best option for you.

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

  • Keep your air ducts clean and change or clean your air filters regularly.
  • Schedule regular inspections to take care of issues 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 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 it comes time to replace any part of your HVAC system, explore Energy Star-certified or other environmentally friendly options.
