Signs You May Need HVAC Repair or Replacement

A faulty or aging HVAC system probably needs professional attention from a technician who can make repairs or install a new unit. Watch out for these common indicators that your HVAC needs service:

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

If you notice any of the above, have a local HVAC technician inspect your system. They can identify problems and let you know whether repair or full HVAC replacement is the better solution.

Cost of HVAC Installation and Maintenance in Fairfield

HVAC installation or maintenance costs change depending on your system. 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 interior units in each room to regulate temperature; these indoor units all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC unit operates similarly to a regular split system. It provides flexibility by providing the option to draw on either electricity or gas for energy.
  • Heat pump: Heat pumps transfer hot and cold air between your home and outside. These systems don't make their own heat or AC, so they work more effectively in moderate climates and may not be as effective during Fairfield's hot summers.
  • Packaged heating and air: Packaged HVAC systems are a great choice for smaller houses. They have a single heating and cooling unit, normally in a basement or attic. This unit is often compact, energy-efficient, and easy to maintain.

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

HVAC Unit TypeCost
Split$2,004-$5,109
Hybrid Split$4,061-$7,482
Heat Pump$3,144-$32,041
Packaged Heating and Air$263-$439

Ways to Save Money on HVAC Costs

It’s important to take care of HVAC repairs and replacements when they are required, 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.

  • Monitor for potential problems. Keeping an eye out for problems, for instance by consistently checking your thermostat and energy bills, lets you resolve them before they get out of hand.
  • Change filters regularly. Cleaning or replacing your air filters every 1–3 months helps air flow smoothly through your system. You should also try to keep debris away from the external sections of your HVAC system as much as possible.
  • Change the position of your blinds seasonally. Leaving your blinds open during the colder months allows passive solar heating to warm your home. Closing the blinds during the summer helps prevent the same heat from getting inside. Doing both helps minimize the strain on your HVAC.
  • Keep your system clean. Regularly cleaning grills, condenser fan blades, ductwork, and indoor evaporator coil helps keep your HVAC system running efficiently and reduces your risk of mold. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.
ServiceCost
Filter Replacement$66-$175
Condensor Cleaning$1,316-$3,947
Thermostat Repair$88-$219
Ductwork Cleaning$421-$1,053

How To Choose a Local HVAC Company

Knowing what makes a trustworthy HVAC company is crucial for an easy 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

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

Check Credentials

It's important to choose an HVAC company that employs technicians with the appropriate qualifications and expertise. HVAC contractors in all states have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, an individual 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 by the state.

In California, HVAC contractors 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. Contractors with employees must also meet insurance requirements. You should also check reviews and complaints on sites like Google Reviews, Yelp, and the Better Business Bureau (BBB). Pick a company with glowing reviews and reports of great customer experiences.

Understand Work Details

Make sure you understand the details of your project before starting. When getting HVAC repairs, have your provider detail which parts need replacement and why. Confirm that your technician will clean and test the entire system after the repair to ensure that everything works. When getting a replacement, ask your contractor to explain the new HVAC system brand, features, model, estimated installation time, and energy efficiency. Before work begins, you should understand the process your provider will use to properly size the system for your home and the price you'll pay.

Compare Warranties

A reputable HVAC company will back its repair services and equipment installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully compare the fine print between contractors and choose the company that provides the most protection at a reasonable price.

Get Quote in Writing

Get a written estimate before HVAC work starts. A full quote includes both materials and labor costs. Make sure you understand and accept all terms before signing the contract.

Frequently Asked Questions About HVAC in Fairfield, CA

Typically, your HVAC system should be inspected twice a year. After that inspection, your HVAC 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 leaks, unusual smells, or strange noises. 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 are generally less busy during these times, so it will be easier to get an appointment. This also helps get your system ready for the summer and winter, the times of the year when it 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. Set your thermostat as close to the outside temperature as you comfortably can, and try to avoid making drastic changes in temperature all at once. Keep your roof in good shape 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 around one to three days to have your HVAC system installed or replaced. If you need just an air conditioning unit or a furnace, this can take anywhere from a few hours up to two days. This timeline can be affected by the size of your home, the accessibility of your system, and any new issues your technician uncovers.

For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. In Fairfield, you'll probably want to choose a unit that's on the higher end of this range. For a house over 1,000 square feet, central air will generally be more effective than window units for cooling.

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 Fairfield, you might be able to make do with a lower-capacity furnace.

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

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

  • Keep ductwork clean, and clean or change your air filters regularly.
  • Schedule 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 aren't able to purchase one, try to keep your inside temperature as close to the outside temperature as you can.
  • When you need to replace part of your system, see if there are Energy Star-certified or similar environmentally friendly options.
