Heating and cooling facts

If you are thinking of buying a new home heating and cooling system….

Or if you simply want to get the most out of your current HVAC system, you probably have a lot of questions on your mind. Compiled here are a few heating and cooling FAQs (and answers). This list is based on some the most commonly asked question by Southern California homeowners looking into HVAC replacement. 

How long will my HVAC system last?

The lifespan of HVAC systems range between 10 and 20 years. That is a pretty big range, and of course there are several factors that contribute to how long your investment in heating and cooling will last. By choosing the right equipment brand for your home along with regular maintenance you can easily get over 10 years out of your HVAC system. It is natural that over time, you will notice that your system’s efficiency will lessen. Furthermore, you might observe a few symptoms like frequent repairs or noises. If you have an HVAC contractor you can trust, they should be able to detect small issues before they become big ones and prevent unnecessary breakdowns.  When you heating and cooling equipment gets to the end of it’s life, you can either have your current system fixed, which could get costly depending on the age of equipment or replaced. The consensus among HVAC experts is that you should opt for the latter as newer systems offer more benefits when it comes to energy efficiency.

How can I lower my energy bill?

One of the best things that you can do to reduce energy consumption is to replace your old system with a newer energy-efficient one. Check out or recent blog post on California HVAC standards.  We advise property owners to adjust the temperature settings by five to eight degrees (up during summer and down during the winter). Keeping a fixed temperature takes the pressure off of the major parts of your heating and cooling system. Installing ceiling fans and changing the direction of the airflow can also help make your home warmer during winter and cooler during summer. Many homeowners like whole house fans, which can be a great cost savings. Vents in areas that are frequently used should not be blocked while vents in areas that are less used may be closed. Consider investing in a programmable thermostat which can set the temperature even if you are outside or asleep.

Most importantly, make sure that your HVAC system is regularly checked and maintained.

Is a bigger HVAC system always better?

In choosing an HVAC system for your home or property, use the Goldilocks principle. Your system should neither be too big or too small for the property. Get a system that is too big and you will have to deal with problems like increased energy consumption and temperature swings. We call this a “right size” HVAC system. Our technicians are trained to carefully calculate all of the functions of your home, like air flow, consistent temps and layout of the home. Just because you have a big house, doesn’t mean one big system will keep you comfortable. There is an art in designing heating and cooling systems that is quite involved. 

When should I replace my system?

Consider replacing your current heating and cooling equipment if it is more than ten years old, if requires frequent repairs or simply stops working. There are some great HVAC financing programs out there to help ease the pain of a big unexpected payment. Find out more about Pace Programs like California First and the HERO program.

Will I need new ductwork installed?

Experts estimate that up to 70 percent of homes have poorly installed ductwork. If you truly wish to save money over the long term and optimize your new HVAC system, have your ductwork inspected. Same with your insulation, it wears down over time. When these two functions begin to fail, the air your HVAC equipment is trying to push into the rooms in your home escapes. This causes your heating and cooling system to work twice as hard, eventually causing parts to fail and energy bills to rise. 

How often should my system be checked?

Ideally, HVAC systems should be checked and serviced at least twice a year, preferably before the start of the summer and winter season but twice a year no matter what time is just fine. This will ensure that your system works optimally. A heating and air tune up will cost less than $100 and will keep your equipment clean, calibrated and operation at the highest level. Also, we recommend you check your equipment warranty. Often, in order to keep your parts warranty in tact, you must have seasonal tune-ups done on your heating and air system.
