We replaced an 18 year old heating and air conditioning unit while it was still operating, We decided to have a hybrid system installed (heat pump with gas backup). Andy gave us a reasonable estimate. The work was performed on time within our budget.

We've had Andy McPhillips do larger HVAC projects for us and now we have him do our regular HVAC maintenance. Love interacting with him and his wife Sandra -- they are easy to communicate with by phone and text. He is prompt, efficient, super knowledgeable, and prices are very reasonable.

Where to Find Good HVAC Help

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.
