Heating and Cooling Company for Repairs
Regardless of whether you’re hearing strange noises from your system or smelling odd odors, Brennan Heating & Air Conditioning can address it with an expert repair. The occasional bad smell or weird sound isn’t merely an annoyance. Either can signal that something’s seriously wrong with your equipment.
Other problems we can fix include short cycling. This is when your heater or AC shuts down after a few minutes of running. Reach out if either your cooling or heating unit leaks fluid or doesn’t put out the right air temperature. Your HVAC system might not cool or warm your entire property evenly, which is another concern we can also investigate.

Graham’s HVAC Contractor for Installations
Getting a new system has a few major benefits. An obvious one is consistent temperatures indoors. If your old setup had problems with cool or warm air or both, you’ll notice an immediate difference in air output once we install your replacement.
Don’t overlook the money-saving aspect of a new installation. Aging equipment can drive up your energy bills through decreased performance and longer run times. Your upgrade will operate much more efficiently, which you’ll see in lower utility costs over time.
Beyond just the heating and cooling aspects, your new equipment could very well increase the value of your home. A brand-new HVAC system could be attractive to buyers, and you might be able to ask more for your home if you’re planning on selling it.
