Signs You May Need HVAC Repair or Replacement

If your home's HVAC system isn't working correctly or nearing the end of its lifespan, you may need to hire an HVAC contractor for repairs or replacement. Watch for these common signs that your system requires expert attention:

  • Frequent breakdowns and need for repairs
  • Higher than normal energy bills
  • Cracking, rust, or corrosion
  • Poor air circulation or uneven heating/cooling
  • Thermostat malfunctions or temperature control issues
  • Refrigerant leaks
  • Odd noises when turning on
  • 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 diagnose problems and let you know whether whether repairing or getting a new HVAC unit is the best solution.

Cost of HVAC Installation and Maintenance in Fullerton

Your HVAC installation or maintenance cost fluctuates depending on the style of unit. Common HVAC unit varieties 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 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 much like a standard split system, but has the capacity to draw on either electricity or gas for power.
  • Heat pump: Heat pumps circulate warm and cold air between your home and the outdoors. They don't produce their own heat or AC, so they function best in temperate climates and may not be as effective during Fullerton's hot summers.
  • Packaged heating and air: Packaged HVAC systems are a smart choice for smaller homes. These systems have a single combined AC and heating, normally located in a basement or attic. They're space-saving, cost-effective, and easy to maintain.

HVAC maintenance costs vary depending on the particular service needed. HVAC systems are complex and can require different kinds of maintenance. Fees for some common services are as follows:

HVAC Unit Type Cost
Split $2,035-$5,187
Hybrid Split $4,123-$7,596
Heat Pump $3,193-$32,531
Packaged Heating and Air $267-$445

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

  • Change the position of your blinds seasonally. Keeping your blinds open in the winter helps you take advantage of passive solar heating. Keeping them closed in the summer helps keep some of this heat out. Both of these measures help reduce the frequency with which you need to run your HVAC.
  • Monitor for potential problems. Keeping an eye out for problems, for instance by consistently checking your thermostat and energy bills, helps you resolve them before they get too expensive.
  • Keep your system clean. Cleaning your ductwork, condenser fan blades, grills, and indoor evaporator coil 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 starts to look dirty.
  • Change filters regularly. Changing or cleaning your air filters every 30–90 days helps air flow efficiently through your HVAC system. We also recommend regularly clearing dirt and debris away from the outdoor sections of your system.

Service Cost
Filter Replacement $67-$178
Condensor Cleaning $1,336-$4,007
Thermostat Repair $89-$223
Ductwork Cleaning $427-$1,069

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 keep your system running efficiently, providing you with effective heating and cooling in your home.

Compare Multiple Bids

Request estimates from at least three HVAC providers. Explain your issues and ask if specialists can inspect your system in person. Compare each contractor's diagnoses, recommended solutions, estimated cost, warranties, and timelines. Avoid companies that pressure you or demand payment before work.

Check Credentials

Look for an HVAC company that employs qualified technicians with 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." Contractors 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 at the state level.

In California, HVAC contractors must be licensed by the Department of Consumer Affairs Contractors State License Board (CSLB). The CSLB considers HVAC contractors to be specialty contractors. All contractors must have four years of experience and be bonded, and contractors with employees must also meet insurance requirements. 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 fantastic customer experiences.

Understand Work Details

Make sure you understand the details of your project before it begins. For HVAC repairs, have your provider detail which parts need replacement and why. Get confirmation that your technician will clean and test your system after the repair to ensure that everything works. When replacing your HVAC, ask the provider to explain the new energy efficiency, model, estimated installation time, brand, 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

Good HVAC companies offer warranties on repairs and installations. The more complete the coverage, the better. Review warranty details between providers and pick the one that offers the best protection for a fair price.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Fullerton, CA

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

Normally, it's a good idea to have your HVAC system inspected 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 typically sees 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 comfortably can, and avoid making drastic changes in temperature all at once. Keep your roof well-maintained and seal any leaks around your windows and doors to avoid letting cool air escape. Similarly, make sure your attic is well ventilated to avoid trapping excess heat in your home.

It takes roughly one to three days to have an HVAC system installed or replaced. If you need just an air conditioning unit or a furnace, this can take between half a day and two days. This timeline will be determined by the size of your house, how easily accessible your system is, and any new issues your technician uncovers.

For a 2,000-square-foot home, you'll need between 2.5 and 5 tons of air conditioning capacity. In Fullerton, you'll probably want to choose a unit that's on the higher end of this range. For homes over 1,000 square feet, central air will 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 Fullerton, you might be able to make do with a lower-capacity furnace.

Usually, HVAC financing is through a third-party lender. If your HVAC company doesn't offer these options, you could consider taking out a loan on your own. Be sure to speak with a financial advisor and your HVAC company to learn what options are available to you and appropriate for your situation.

There are a number of 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.
  • Schedule regular inspections to take care of issues as they come up.
  • Make sure your doors and windows are well-sealed and keep your attic well-ventilated.
  • Install a smart thermostat. If you aren't able to purchase one, try keeping the temperature indoors as close to the outside temperature as is comfortable.
  • When replacing part of your HVAC system, explore Energy Star-certified or similar environmentally friendly options.
