Air conditioning has been in use for many years, but it was not until the late 1800s that the first system was installed. The inventor of the air conditioner is Willis Haviland Carrier and his company, Carrier Corporation. Today there are several different types of HVAC systems available to homeowners, including central air systems and whole-home window units. It is no surprise that HVAC systems have evolved dramatically over time. There are many factors to consider when deciding what type of system is best for your home, and the pros and cons depend on the specific needs of each individual homeowner.

Older homes may need a different type of system than newer ones because they were built before we had knowledge about how energy efficient our heating and cooling systems should be. Today there are so many options out there it can be difficult to know which is the best one for you! The most recent change to HVAC systems was the introduction of zoning. Zoning enables you to control the temperature in different areas of your home, making it easier for each family member or room’s occupants to feel comfortable. It can also help reduce energy consumption by delivering only as much heat as is needed, which may be especially helpful during times when electricity rates are high.

Another air conditioning Redwood City option that has become more popular recently is a programmable thermostat, which lets you adjust the temperature settings according to your daily schedule and save money on heating and cooling costs over time. With these new advances in HVAC technology, there has never been a better time than now to get a new system installed at your home!

What is a heating and air-conditioning system?

A heating and air-conditioning system is an appliance that provides the necessary warmth in your home. It also takes care of cooling when needed, while also filtering out dust and other airborne pollutants that might make you sick.

A heating and air-conditioning system is a mechanical device that provides thermal comfort by regulating the temperature of buildings. The systems are made up of various parts, including a furnace, ductwork, thermostat, filters and more.

This includes both heating (in cold weather) and cooling (in hot weather). In the United States, most residential and commercial buildings are equipped with HVAC systems. The HVAC system may have up to four components: an outdoor unit, an evaporator coil inside the building, a condenser coil outside the building, and refrigerant piping in between. These components work together to provide either heating or cooling as needed throughout the year.


What is the difference between heating and air-conditioning?

Many people do not know the difference between heating and air-conditioning. There are some key differences that homeowners should be aware of when deciding to invest in one or the other. Air conditioning cools a house by blowing out hot air from inside through an outside unit, while heating warms a home by blowing warm air into it through an inside unit. Heating systems warm up an indoor space by transferring heat from one area to another. These systems can be fueled by natural gas or electricity. The most common types of heating include furnaces, boilers, and radiators. If you live in a cold climate, you will need both types of equipment to stay comfortable throughout the year!

How do I know if my HVAC system needs repair?


  • You hear strange noises coming from your unit.
  • Your air conditioning is not blowing cold air anymore.
  • The fan in your heat pump does not turn off when it should.
  • The temperature in one or more rooms is too hot or too cold for anyone to be comfortable.
  • High energy bills. If you notice that your energy bills have been increasing in the past few months and it is not because of a change in weather, it may be time to get an inspection done on your heating and cooling unit.
  • Dirty filters or coils. Dirty air filters can lead to higher utility costs as well as dirty vents which can make allergies worse or even cause respiratory problems in children and adults who suffer from asthma or other breathing conditions. Filters should be changed monthly while coils should be inspected annually by a professional technician.
  • Strange smells coming from vents or outside the house.

Common causes of HVAC problems


  • Dirty filters: Filters play an important role in any heating or cooling system by capturing dirt and particles that could otherwise damage your unit’s motor or air quality inside your home.
  • Faulty thermostat wiring: A faulty thermostat wire can lead to overheating or underheating in your home.
  • Inadequate ventilation in the area where ducts are installed. If air seems to be coming out from the vents but is not very warm, there may be something blocking airflow or incorrect ductwork in place which needs fixing.
  • Excessive humidity due to improper air filtration or water leaks. If humidity levels are too high in your home, it could mean that condensation is occurring inside your unit and causing mold growth among other issues. This should be addressed by installing a humidifier with an anti-microbial cartridge into your system.
  • Improper installation or insufficient maintenance. Properly maintaining your heating or cooling system will help keep it running efficiently and effectively.

Tips for saving energy and money on heating bills

With winter right around the corner, you may be thinking about how to save money on your energy bills. The following are some tips to help you keep your home warm without spending too much.

  • Install a programmable thermostat – this can make it easier for you to set an optimal temperature in the morning and evening so that you do not have to worry about constantly adjusting it throughout the day.
  • Add insulation in places like walls or floors – this will help reduce drafts and keep heat inside your home more effectively.
  • Seal up any cracks or leaks with caulking, weather stripping, or foam sealant – these materials will prevent cold air from seeping into areas of your home that should not be exposed to it.
  • Ventilate your house by opening windows for at least 15 minutes every hour during cold days outside of peak hours (8am-5pm)
  • Use space heaters as needed rather than using central heating units that run constantly

How often should my HVAC be serviced?

When HVAC systems are not maintained, they can be more prone to breakdowns. You may experience problems with airflow, temperature control, and energy efficiency. HVAC maintenance ensures that your HVAC system is running smoothly and efficiently throughout the year by hiring a professional HVAC company for routine inspections on a regular basis. The frequency of HVAC service will depend upon how often you use your HVAC system.
