Consumer Comments for Sierra Heating & Air Conditioning

Consumer from NEW CARROLLTON, MD

Jim and his assistant arrived less than 3 hours after I called (as a new customer) and got right to work diagnosing and ultimately fixing my 30-year old central air conditioning system, which just refused to come on. The problem was not at all obvious. As a career engineer, I really appreciate the care Jim took in diagnosing the problem, which involved checking (i.e., measuring and running various quick tests on) key aspects of the system which could be the cause. I appreciate his persistence, and the time he took to find and fix the problem. I’m quite sure that his persistence ultimately saved me quite a bit of money, since I can imagine other companies just telling me it was too old to be fixed — Jim never hinted at that. He seems to be someone you can trust to fix what he’s called to work on, if it’s possible to fix, to tell you the truth when he finds it, and also someone who really finds satisfaction in sticking with the job till it’s done.

Strange experience. I needed a new heat pump system installed. Called Sierra because it had these good Consumer Checkbook ratings. A person picked up the phone after 3-4 rings and mumbled "Hello." Not sure if I had dialed correctly, I asked if I'd reached Sierra. He said yes, but it was clear he was not prepared to handle a business call. To be honest, it sounded like he'd been asleep (I called in the middle of a normal business day). I explained that I needed an estimate for a system installation. He asked for my name and phone number, then said "I will try to call you back, either at the end of this week [it was only Tues.] or at the beginning of the next, to set something up." I asked if we couldn't schedule a semi-firm appointment for an estimate and he said "Oh no" and added that he had too much chaos in his schedule for that. I asked for his name and he said "Jim." It's now been about a week and a half and Jim never called me back, despite the job being worth thousands. Who leaves that much money on the table, I wonder? The whole experience was so unprofessional and unpleasant and strange.

Jim at Sierra Heating and Air Conditioning is the most dependable and exacting service provider I have experienced in all the years I have had work done on my HVAC systems. Several years ago, he resurrected a previously purchased system that the company I purchased from declared DOA. That company tried to get me to purchase another NEW system from them. I called Sierra, and Jim suggested that he take a look thinking perhaps he could do something. That's when Jim got that system working. I got several more years out of that system, but eventually purchased a new system from Sierra. Just recently, they provided superior, and extraordinarily timely, service when a timer on the fan stopped functioning. When I called on the hottest day this year, he came within half hour and had it fixed in 15 minutes. No charge. Bless them. Highly, highly recommend!!!

Where to Find Good HVAC Help

To make sure your heating and air-conditioning systems work when needed, they must be properly installed and maintained. We’ve rated area heating and air-conditioning services for quality and price.

What to Do If You Need HVAC Repairs

If you need repairs to heating or air-conditioning equipment, our ratings of local businesses will help you find a good company to perform them.

Choosing New HVAC Equipment and Getting It Installed Properly

How well a new HVAC system performs, and how much it costs, depends heavily on its design and the quality of installation. It’s important to make the right decisions—and there are many to make. You also must make sure to get a fair contract.

HVAC Equipment Features to Consider

If you are installing new equipment, in addition to making choices about energy efficiency, you will need to decide whether to pay extra for various features. Here is a summary of the types of add-ons.

Maintaining Your HVAC Equipment

The most important maintenance task for HVAC systems is something you can do yourself—replacing the air filter. Check your filter monthly. When a filter has a matting of dirt—i.e., it’s difficult to see through when you hold it up to a light—it’s time to replace it.

HVAC Maintenance Contracts Are Usually Bad Buys

Rather than paying for individual maintenance visits and repair jobs, you might consider getting a service contract for air-conditioning and/or heating equipment. Many companies try to persuade customers to enter into such contracts.
