Signs You May Need HVAC Repair or Replacement

An HVAC system that's not working properly or outdated likely needs professional attention for repairs or replacement. Watch for these signs that your system needs service:

  • Odd noises when turning on
  • Unusually high energy bills
  • Uneven heating/cooling or poor air circulation
  • Corrosion, cracking, or rust
  • Thermostat malfunctions or temperature control issues
  • Refrigerant leaks
  • 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 technician can complete an inspection, diagnose problems, and advise you whether you should repair or replace your HVAC unit.

Cost of HVAC Installation and Maintenance in Suisun City

Your HVAC installation or maintenance cost fluctuates depending on the type of unit. Common HVAC unit types include the following:

  • Split or mini-split: Homes without ductwork for centralized climate control often have split or mini-split HVAC systems. These systems consist of indoor units in each room to control temperature. These indoor units connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system operates similar to a normal split system, but has the benefit of being able to utilize energy from either gas or electric sources.
  • Heat pump: Heat pumps exchange warm and cool air between your home and outside. They don't create their own heating and cooling, so they work more efficiently in more mild climates and may not be as effective during Suisun City's hot summers.
  • Packaged heating and air: Packaged HVAC systems are good for smaller homes. They consist of a single heating and cooling unit that's usually located in a basement or attic. This unit tends to be efficient, compact, and easy to maintain.

The amount you spend on HVAC maintenance also depends on the kind of work being done. HVAC systems are complicated and can 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.

  • Change filters regularly. Air flows best through your HVAC system when you replace or clean the filters every 30–90 days. Also avoid letting debris pile up on the outdoor parts of your HVAC.
  • Keep your system clean. Keeping your grills, indoor evaporator coil, condenser fan blades, and ductwork clean enables your HVAC system to function properly and lowers the risk of mold. The National Air Duct Cleaners Association recommends cleaning your home's HVAC system when you notice things starting to get dirty.
  • Monitor for potential problems. Monitoring the efficiency of your HVAC system — for instance by reviewing your thermostat settings and energy bills — helps you identify and fix problems before they get out of hand.
  • 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 lowers the amount of work your HVAC system must perform.
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

It's important to know what makes a good HVAC company. Working with a contractor that's properly licensed and highly experienced 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

Contact at least three HVAC companies for quotes. Explain the issues and have technicians visit to inspect your HVAC system if possible. Compare the contractors' explanations, solutions, estimated costs, warranties, and timeframes. Avoid companies 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 mandatory 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.

HVAC contractors in California 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, and contractors with employees must also meet insurance requirements. Also look at a company's reviews and complaints on sites such as the Better Business Bureau (BBB), Yelp, and Google Reviews. Pick a company with glowing feedback and good customer testimonials.

Understand Work Details

Always make sure you understand 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 system, ask the contractor to describe the new model, features, energy efficiency, brand, and estimated installation time. Before signing a contract, 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

Trustworthy HVAC companies back their work with warranties. Look at warranties from different companies, remembering that broader coverage is better. Look for the provider that offers the most coverage for a reasonable 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. Make sure that you agree to all terms before signing the contract.

Frequently Asked Questions About HVAC in Suisun City, CA

Typically, you should have your HVAC system inspected twice a year. After an inspection, your technician will tell you what services are needed. You should also call a technician 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 of the year to have an HVAC inspection are the spring and fall. Technicians tend to be less busy during these times, so it will be 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 making it easier for your HVAC system 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 in good shape and seal any leaks around your doors and windows to avoid letting cool air escape. Similarly, make sure your attic is well ventilated to avoid trapping excess heat in your home.

For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. In Suisun City, 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 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 Suisun City, you might be able to make do with a lower-capacity furnace.

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

There are a number of 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 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 the temperature indoors as close to the outside temperature as is comfortable.
  • When it comes time to replace any part of your HVAC system, explore Energy Star-certified or similar environmentally friendly options.
