The owner Mike was amazing. He gave us lots of info about equipment and price options for new heating & AC, checked our electrical and venting systems to make sure they would accommodate and be compatible with the new equipment.and he was very flexible about the installation timing. He was easy to reach when we had questions throughout the whole process. Price we paid may not have been lowest but it was fair & reasonable considering how much time & patience he invested in us.

I WOULD AVOID -- IT HAS CHANGED OWNERSHIP. It was great before, but this time we needed a repair and a modification. A guy in sunglasses and tattoos showed up. He couldn't do the modification (but coincidentally some unrelated electronic circuits in the same bundle stopped working around the same time). Then he did the repair, which was really just an adjustment. As he was leaving he gave me detailed measurements that seemed unnecessary about another system that was working "but might fail in a year or so". Six weeks later the furnace stopped working and I asked them to come out under the repair warranty. This time two guys showed up and after a long time in the furnace they said that their repair was fine, but that two other major systems (including the one they had told me about in the previous visit) had apparently failed (during a six week period in the summer) and I should probably buy a new furnace. Then they tried to charge me for their warranty visit saying the warranty was 30 days. Turns out they also have a new owner. Make of that what you will.

Completed a somewhat difficult job, with demanding requirements. Installers Waldo and Pedro were hard-working, cooperative, and meticulous.

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, 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.
