The key to a trouble-free home comfort system is annual maintenance for both your furnace and your air conditioning unit. The problem is, most people don’t think about maintenance until their system stops working and needs a repair.

Sherlock makes it easy to stay on track with routine maintenance.  We encourage all of our clients to join our VIP Comfort Club which includes one furnace service and one air conditioning service per year.  Additional benefits include priority scheduling and exclusive promotions and discounts.  Let us handle remembering the maintenance so that your home comfort system remains efficient and consistent for years to come!

Replacement and Installation

There comes a time in the life of every furnace or air conditioner when replacement is necessary.  Or, maybe you’ve lived through your last summer without AC and it’s time to add it on.  Perhaps your current equipment is still functional, but you don’t want to miss out on the energy savings that comes with a newer, high efficiency model.  No matter what your needs, we’re here to help.

Our top quality lines of high efficiency, modern and technologically advanced equipment is not only better for the environment, it’s good for your budget.  These newer units can save you money month after month on energy bills while providing a more comfortable indoor environment and producing less noise than their older counterparts.

When you’re ready for replacement, Sherlock Heating and Air Conditioning offers some of the finest installation technicians in San Diego County.  We believe that the entire installation process should be as seamless as possible.  Our team will communicate with you every step of the way to ensure that you’re getting the equipment you want with the features you need, all at a great value.

From the initial consultation with one of our comfort advisers to design your system, all the way through the installation, our team is here to keep you informed and answer your questions every step of the way.  We’ll clearly explain the process, protect your home during the installation, train you on how to use your new system, and follow up afterwards to answer additional questions.
