According to a 2015 government survey, 87% of the homes in the United States use air conditioning and 65% of those homes have central air conditioning. Most of the homes with central air conditioning have programmable thermostats, but approximately two-thirds of the homes with central air do not use this feature to make their homes more energy efficient.[56]

Modern air conditioning emerged from advances in chemistry during the 19th century, and the first large-scale electrical air conditioning was invented and used in 1902 by England inventor Willis Carrier. The introduction of residential air conditioning in the 1920s helped enable the great migration to the Sun Belt in the United States.[citation needed]


HVAC services is our go to contractor when it comes to our HVAC needs. Back in 2013, we were dealt some unforeseeable home projects, as our  HVAC was failing and needed to replace the whole system, e.g. Furnace, Blower, A/C, Condenser, Vents, etc... We reached out to a few HVAC companies (Contra Costa Heating and Air, EP builders, High Performance Heating and Air) so we could compare the bids for the job. We have had some issues with past contractors and after thoroughly screening a few of the above mentioned HVAC contractors, we awarded the bid to HVAC services because of their superior customer service and very reasonable pricing.

You’re constantly repairing your HVAC: If your heating and cooling system has needed repairs more than once or twice in the past few years, it may be time to take the leap with a replacement system. The money you spend repairing older equipment can often be better used towards the purchase of newer, energy-efficient HVAC systems. Here’s a simple guide: If your labor and parts cost upwards of $1,000, look toward replacement. 
The condenser fan is another important HVAC element that must be maintained. Condenser fans that contain oil ports should be lubricated at least annually. The outside condenser should also be shielded from direct sunlight if possible. Keeping vegetation at least two feet away from outdoor HVAC units will also promote higher performance and potentially lower energy bills due to higher efficiency. The further away vegetation is, the better an HVAC unit will operate.

The liquid refrigerant is returned to another heat exchanger where it is allowed to evaporate, hence the heat exchanger is often called an evaporating coil or evaporator. As the liquid refrigerant evaporates it absorbs energy (heat) from the inside air, returns to the compressor, and repeats the cycle. In the process, heat is absorbed from indoors and transferred outdoors, resulting in cooling of the building.
First, it is wise to stick with a company that specializes in HVAC services. While many general handyman companies may do some things with AC units, a company that specializes in air conditioning and heating is always a better option. Because air conditioning repairs can be quite costly, depending on the particular problem, it is best to work with highly trained HVAC professionals to ensure quality work.

Are there watermarks on your ceiling? Visible leaks around your outdoor unit? Has your AC system completely stopped working? If you notice any of these signs, it’s in your best interest to call an AC technician to fix the issue before it causes more problems for you, your AC system, and your home. To learn more about potential AC malfunctions and how we fix AC issues, visit our AC Repair page.


The time it takes to install an AC unit and the associated cost depends on the square footage of your home. Many homeowners spend between $3,677 to $7,151 for a contractor to put in a new central air system.A family with a 2,000-square-foot house that already has a forced-air heating unit can expect to pay $3,500 to $4,000 for a cooling system. If technicians don't need to make any changes to the duct-work, then the project should take them an average of two to three days.
Before opening the electrical cover on the A/C unit, be sure to shut off all power to the compressor unit and the indoor furnace or air handler, and verify that it is off. Note that this may mean shutting off a circuit breaker that serves the furnace and air handler, and then, near the compressor, pulling out the disconnect block (or shutting off the 220-volt power) to the outdoor compressor.
A contactor is a $25 mechanical relay that uses low-voltage power from the thermostat to switch 220-volt high-amperage current to the compressor and condenser fan. AC contactors can wear out and are at the top of the list of common air conditioning service failures. Even if your contactor is working, it pays to replace it every five years or so. Unscrew the old contactor before removing the wires. Then move the wires to the new unit (photo 6).
