My HVAC isn’t cooling or heating properly. What could be wrong?
HVAC systems are complex, so several pieces could be causing the issue. For a comprehensive assessment of the problem, call G & R Heating and Air. We’ll send an expert technician to your home to inspect your system and find the source of the problem, go over your options with you, and answer your questions.
My system is making strange noises. Is that a problem?
Yes. In most cases, if your HVAC is making strange sounds, it’s a symptom of a problem that shouldn’t be ignored. If you’re hearing high-pitched squealing, a grinding noise, banging, or anything else out of the ordinary, call your local HVAC experts for repair.
My energy bills have been high. Can you help me improve efficiency?
A simple maintenance appointment may improve the efficiency of your heating and cooling system, which lowers your energy bills. Schedule your tune-up and save.
Should I repair or replace my current HVAC system?
A general rule is to judge whether the costs (and stress) of needing constant repairs on your system are more than the cost of purchasing a new heater or AC. If you’re ready for an upgrade, getting a new HVAC system is easy with our financing options.
What are my options for a more energy-efficient system?
A heat pump is an energy-saving alternative to an older furnace. You can also find highly efficient air conditioners and gas or electric furnaces with programmable thermostats, air filtration systems, smart home integration options, and more.
