After years of struggling with an HVAC system that was not powerful enough to cool or heat my house, I decided to upgrade the whole system in May 2019. The job included relocating the furnace unit from my hallway closet to the attic, as well as... relocating the condenser unit to my backyard to be in compliance with city code. I've had the new system for almost a year, so I am writing this review to say that Angel and his Comfort Time team were really a pleasure to work with. Now I have an energy efficient system that is the right size for my house, and it keeps the whole house cool/warm and comfortable. Plus my utility bill over last summer was lower because I didn't have to run the air all day just to try to keep the house cool. Angel and his team were punctual, left the workspace clean every evening, and answered all my questions as we went along in the process. I really appreciated their attention to detail and responsiveness. I have had no issues with the HVAC, and I am very pleased with my decision to go with Comfort Time Heating & Cooling. They are top notch in my book.read more

The majority of the HVAC solutions we offer come with a 10-Year Care-Free Guarantee

Like A New Car You Need To Provide Periodic Maintenance. The Same Goes With Your New System.

As Long As We Continuously Service Your System At Least Once A Year You’re Covered.

What to know before you choose any cooling and heating contractor to install your new system.

Do you need permits?
The simple answer to this is yes and no. Always get permits if you can. We always recommend getting permits. It ensures that your home isn’t going to burn down when you turn on your heater and cause a massive electrical short when you turn on your A/C. The building inspector is also going to make sure that your HVAC contractor isn’t cutting corners. In California a third-party energy audit is required to pass inspection, another private company needs to test the equipment that was installed to ensure it runs to manufacturer specifications and efficiency ratings. The test is done by a specialized company that is not part of or associated with HVAC contractors, so it is an unbiased test. We understand that some homes have un-permitted additions or alterations and getting city inspectors out to the home is the last thing the owners would want. We will always try to keep our customers happy, but we still strongly recommend getting permits and inspections. Either way there is a risk that if the building department finds out that you’ve done any major home improvement project without a permit, they can make you remove it and possibly fine you and the contractor. So, if you can get permits and don’t have to worry about past projects, get them, it will give you the peace of mind it was done right the first time.

What size of unit do you need?
There are a lot of options on what size you need for the home. The most common way to determine the right size of an air conditioning and heating system in southern California is by square feet (400sq. ft. per ton), but that is not always the most accurate. Windows, how the sun hits the building, hot and cold spots in the house, and most importantly the buildings insulation can all affect the size required. All these things add and subtract heat from your home and should be used to find the right sized HVAC system needed.

What features do you want?
The old school way of putting A/C or heat in your home was just a simple on/off switch for hot and cold. Modern technology allows us to provide even air temperature throughout your home with the right humidity using the least amount of energy. Plus keeping it quiet when you sleep or watch TV. Ask your contractor how the unit works and what options you have like, single stage, two stage, variable speed and ECM motors. An important thing to remember is that it’s going to last 15 to 20 years, paying a little more now will save you more than just money. 

Does the brand name matter?
Brand names like Trane, Carrier, Lennox, Goodman and Rheem make 80% of all equipment sold in the USA. They change the paint, put a different name and charge the contractor a different price. At the end of the day the Brand names don’t mater, what does matter are the features and warranties offered on equipment.

Is the company installing my equipment licensed?
Always go with a licensed contractor. You can check their license status in California with the contractor’s state licensing board (cslb.ca.gov). In California, to install, service and repair HVAC equipment for homes and business, you need a C-20 classification.  Do not use a general contractor to install your A/C system (B classification) they will either act as the middle man and sub-contract out the work or not know what they are doing.  

What type of insurance should the contractor have?
Workers Compensation insurance is number one! In the HVAC industry there are thousands of companies working without it. They will have “under the table” employees working for them. If you hire a contractor to do work in your home and their employee gets hurt in your home, you can be held responsible for damages. They can also file a claim against your home insurance.  Ask for a copy of insurance before they start or you can check the with the state contractor licensed board.  

General Liability insurance, you want to be covered if something happens to your home during or after the installation.  Make sure the contractor has at least 1-million-dollar general liability insurance policy. Bonded:  ask to see their bond, this is the easiest way for you to recoup any losses if something goes wrong, but it usually only covers up to $10,000 worth of damage.

You have choices when it comes to home comfort

Variable Speed A/C and Heat

High efficiency heating and cooling units that will automatically adjust the flow of warm or cool air for ultimate comfort.

High Torque ECM

Slow start up when first turned on, which saves energy on startup. Second most efficient design after variable speed.

Two Stage

Two levels of operation which saves energy during non-peak heating and cooling. Runs at lower stage most of the time.

Single Stage

One level of operation with no difference between peak or non-peak heating or cooling demands. Least efficient design.
