Consumer Comments for Delta Service

The person who came to check our HVAC that wasn’t working said there maybe a leak. Charged 400 to put refrigerant in and said they weren’t able/knowledgeable regarding how to find a leak. Two months later when the old system broke down, we called in person recommended now doing a leak check. We had another company out who explained that having that much refrigerant put back in was a great indicator that there was an absolute need either for a leak check or given the age of the system, probably a replacement needed. They came out to take a look, and we are happy we went with the other company. We could’ve saved hundreds of dollars if Delta had been competent initially. No offer on Delta part at any point to take responsibility and follow up call.

I’ve used Delta Service for over 20 years. They are the best in terms of quality service and integrity. I highly recommend them to anyone looking for an HVAC company.

Skyler came on busy day after Labor Day, quickly diagnosed and solved the problem with my non-functioning air conditioner for only a nominal charge. He didn’t have time then to check out my functioning upstairs air conditioner but returned a week later and did so. He installed a new capacitor and a pound of refrigerant. All in all, very competent and timely service and maintenance. I will use Delta Service again.

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.
