About Us

I’m James Merts, Owner of A1 Heating & Air. If you need Service, Repair, Maintenance or Replacement of your old heating and air conditioning system in the Sacramento area, you came to the right place.


We are Nate, BPI, and EPA certified. This means we have the expertise to properly diagnose problems and recommend solutions for your comfort needs.

Why A1 Heating and Air?

We provide better service and prices than the larger companies you may call. In fact, we guarantee that you will be happy with the work we provide or we will make it right, free of charge.

Tired of someone trying to sell you something every time they perform maintenance for you? We promise only to service your equipment according to accepted standards and will only provide you information on the condition of worn out or failing parts if necessary in order to work correctly. Our promise: no cheap sales pitches, just honest, hard work.

Have you had a technician out for a tune up only to find that the system you thought was fine was in dire need of extensive repairs or even replacement?

While that may be some company’s MO, it will never be the case with A1 Heating and Air unless absolutely necessary. We promise only to recommend a new unit when it makes sense mechanically or because of high operating cost.

We also provide a quick diagnostic before giving a quote on replacement unless you direct otherwise. We have found that many times a customer will call us out for a quote on a new system only to find that it needs minor repairs rather than a large investment.

Like what you hear?

Give us a call at 916.400-4266 and we’ll do something unique: Under Promise and Over Deliver, something other companies just seem to have forgotten, and we do every day.
