Signs You May Need HVAC Repair or Replacement

A malfunctioning or aging HVAC system probably needs attention from a professional who can make fixes or install a new unit. Look out for these common indicators that your HVAC needs service:

  • Odd noises when the system turns on
  • Poor air circulation or uneven heating/cooling
  • Unusually high energy bills
  • Cracking, corrosion, or rust
  • Refrigerant leaks
  • Thermostat malfunctions or temperature control issues
  • Frequent breakdowns and need for repairs
  • 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, identify problems, and recommend repairing or replacing your HVAC unit.

Cost of HVAC Installation and Maintenance in Lake Forest

HVAC installation or maintenance prices vary depending on your system. Common HVAC unit types include the following:

  • Split or mini-split: If your home doesn't have the right ductwork for central air or heating, you probably have a split HVAC system. Split or mini-split systems consist of interior units that regulate the temperature in individual rooms, and that are all connected to an outdoor unit.
  • Hybrid split: A hybrid split HVAC unit operates similarly 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 house and the outdoors. They don't make their own heating and cooling, so they work more efficiently in more temperate climates and may not be as effective during Lake Forest's hot summers.
  • Packaged heating and air: Packaged HVAC systems are a practical choice for smaller homes. These systems have a single heating and cooling unit, typically located in a basement or attic. They're small, cost-effective, and easy to maintain.

HVAC maintenance prices vary based on the services needed. HVAC systems are complex and may need several types of maintenance. Prices for common jobs are as follows:

HVAC Unit TypeCost
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. Fortunately, there are some steps you can take to reduce wear and tear on your system.

  • Change filters regularly. Replacing or cleaning your air filters every 30–90 days helps air flow efficiently through your system. Also try to keep debris away from the outdoor portions of your HVAC system as much as possible.
  • Keep your system clean. Keeping your condenser fan blades, ductwork, indoor evaporator coil, and grills clean enables your HVAC system to function effectively and lowers your risk of mold. The National Air Duct Cleaners Association suggests cleaning your home's HVAC when you notice it starting to get dirty.
  • Monitor for potential problems. Monitor your system for issues, for example by routinely checking your thermostat and energy bills. This helps you address issues before they get too expensive.
  • 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 decreases the amount of work your HVAC system needs to do.
ServiceCost
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

Knowing what makes a trustworthy HVAC company is key for a successful installation or repair. An experienced, credentialed HVAC contractor gives you confidence your system can provide reliable heating and air conditioning year-round.

Compare Multiple Bids

Contact at least three HVAC providers for quotes. Describe your issues and schedule an in-person inspection if possible. Compare providers' diagnoses, suggested repairs, estimated costs, timeframes, and warranties. Avoid providers that pressure you or demand upfront payment.

Check Credentials

Look for an HVAC company that employs qualified technicians who have the necessary licensure and training. HVAC contractors in all states 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 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 are required to have four years of experience and to be bonded. Contractors with employees must also meet insurance requirements. You should also look at reviews and complaints on sites like the Better Business Bureau (BBB), Yelp, and Google Reviews. Pick a company with glowing reviews and testimonials about good customer experiences.

Understand Work Details

It’s important to know what the work process will look like. For HVAC repairs, the company should explain the particular parts that need replacement and why. Get confirmation that your technician will clean and test your system afterward to guarantee everything is working correctly. When replacing your HVAC, ask the contractor to describe the new features, model, energy efficiency, brand, and estimated installation time. Before signing a contract, ask how your provider plans to accurately size the unit for your home and how much it will cost.

Compare Warranties

Trustworthy HVAC companies back their work with warranties. Look at warranties from different companies, keeping in mind that broader coverage is better. Look for the company that offers the most coverage for a fair price.

Get Quote in Writing

Get written quotes before starting any HVAC work. The quote should cover costs for both materials and labor. Read all terms carefully before signing.

Frequently Asked Questions About HVAC in Lake Forest, CA

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

The best times to have your HVAC system inspected are the spring and fall. Technicians are often 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, the times of the year when it 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 can, and avoid making drastic changes in temperature all at once. Keep your roof in good shape and seal any door or window leaks to help keep cool air in. Similarly, make sure your attic is well ventilated to avoid trapping excess heat in your home.

Generally, whole-system HVAC installation or replacement takes one to three days. Installing or replacing a furnace or air conditioning unit may take anywhere from a few hours up to two days. The exact amount of time will be based on factors like the size of your home, how easily accessible different sections are, and whether your technician discovers any problems.

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

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