Signs You May Need HVAC Repair or Replacement

If your home's HVAC system is malfunctioning or nearing the end of its lifespan, you may need to hire an HVAC contractor for repairs or replacement. Look for these common indicators that your system requires professional attention:

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

These HVAC red flags indicate that you should have your system evaluated. A local company can complete an inspection, identify problems, and recommend repairing or replacing your HVAC unit.

Cost of HVAC Installation and Maintenance in Ontario

HVAC installation or maintenance prices vary depending on your system. Common HVAC unit types 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, and that are all connected to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions in the same way as a normal split system, but has the advantage of being able to utilize energy from either electric or gas sources.
  • Heat pump: Heat pumps move hot and cold air between your home and outside. They don't make their own heating and cooling, so they work more effectively in more moderate climates and may not be as effective during Ontario's hot summers.
  • Packaged heating and air: Packaged HVAC systems work best in smaller houses. They consist of a single combined air conditioner and heating unit, commonly located in an attic or basement. This unit is typically space-saving, cost-effective, and straightforward to maintain.

HVAC maintenance prices vary based on the specific services required. HVAC systems can be complicated and potentially require a number of services. Costs for typical jobs are as follows:

HVAC Unit Type Cost
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 make any essential HVAC fixes or replacements as needed, though they can be expensive. The good news is that homeowners have methods to decrease the effect of wear and tear and reduce the frequency of breakdowns.

  • Change the position of your blinds seasonally. During winter, leave your blinds open so your home benefits from passive solar heat. In summer, keep blinds shut to block out heat. Doing both helps minimize the amount of work your HVAC system must perform.
  • Change filters regularly. Air flows through your HVAC system most effectively when you replace or clean the filters every 30–90 days. Also avoid letting debris pile up on the outside areas of your HVAC.
  • Keep your system clean. Keeping your ductwork, indoor evaporator coil, condenser fan blades, and grills clean enables your HVAC system to function properly and lowers the 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. Keeping an eye out for problems, for instance by routinely checking your thermostat and energy bills, lets you resolve them before they get out of hand.

Service Cost
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

It's important to know what makes a good HVAC company. A properly licensed contractor with the right experience will give you confidence that they can fix your system, providing you with effective heating and cooling for your home.

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 providers that pressure you or demand payment upfront.

Check Credentials

Look for an HVAC company that employs skilled technicians with the necessary licensure and training. In all states, HVAC contractors must 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.

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 must have four years of experience and be bonded. Contractors with employees must also meet insurance requirements. You should also read reviews and complaints on sites like Yelp, the Better Business Bureau (BBB), and Google Reviews. Pick a company with glowing reviews and reports of great customer experiences.

Understand Work Details

Always make sure you know the details of any project. When HVAC repairs are required, your provider should specify which parts need replacement and why. Confirm that your technician will clean and test your system after repairs are finished to ensure that it’s working properly. When replacing your HVAC, ask the contractor to describe the new estimated installation time, energy efficiency, features, model, and brand. Before work starts, 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

A trustworthy HVAC company will back its repair work and installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully compare warranty terms between contractors and choose the provider that offers the greatest protection at 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 materials and labor. Make sure you understand all terms before signing a contract.

Frequently Asked Questions About HVAC in Ontario, CA

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

The best times to have an HVAC inspection are during the spring and fall. Technicians tend to be less busy during these times, making it easier to get an appointment. This also ensures that your system is ready for the summer and winter, when it typically gets the most use.

You can save energy during the summer by reducing the amount of power your HVAC system uses to keep your home cool. Keep your thermostat temperature as close to the outside temperature as you can, and avoid making drastic changes in temperature all at once. Keep your roof in good shape and seal any window or door leaks to avoid letting cool air escape. Similarly, ensure that your attic is well ventilated to avoid trapping excess heat in your home.

It takes between one and three days to have an HVAC system installed or replaced. If you only need an air conditioning unit or a furnace, this may take anywhere from a few hours up to two days. This timeline will be determined by the size of your home, the accessibility of your system, and any new issues your technician runs into.

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 explore units on the higher end of this range. If your home is larger than 1,000 square feet, central air will generally 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). In Ontario, you might be able to make do with a lower-capacity furnace.

Your HVAC company may have financing options via a third-party lender, or you might be able to obtain a loan on your own. It's smart to discuss payment options with a financial advisor and your HVAC company to make sure that you're choosing the best option for you.

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

  • Keep ductwork clean, and change or clean your air filters on a regular basis.
  • 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 aren't able to purchase one, try to keep your inside temperature as close to the outside temperature as is comfortable.
  • When replacing part of your system, see if there are Energy Star-certified or similar environmentally friendly options.
