If you’re asking yourself about whether a repair for your faulty HVAC system is too costly, it’s either because a) your heater is starting to fail at the end of the season after a long winter, or b) you’re concerned about your old air conditioning system and if it will manage the coming summer weather.
In either case, you’re already asking the right question. Repairs for an HVAC system early on in its service life are usually worth the price, and many will fall under the warranty. With older systems that are out of warranty, price becomes a bigger concern.

To do otherwise risks more than you comfort: it can present a health hazard too.

We’ve just come through 
Winter is the time when our heating systems are put under more strained than ever, and when problems arise, they tend to do so just when 
Forced-air furnaces are a common type of heating system in Delaware and Maryland: generating heated air either through gas-fed burners or electrically powered coils, then blowing the heated air through the same ducts used by the air conditioning system. It’s simple, effective and inexpensive, which is why such heating systems remain so popular. But it can also give you a quick and easy way to spot one of the most common signs of trouble in your heater: low air flow.
