On 1/12/2026 John Moreno had this to say:
Very fast and reliable. John did a repair on a very old central air unit at my home, he was very upfront in letting me know that it was just a temporary fix that it wouldn't last forever. And that, I needed a new unit. Well, his temporary fix got me through 2 years with that old unit until I could finally get a new one installed by him I would highly recommend.

FAQ

What services do you offer?

At G.P.S. Heating & Cooling we provide a full range of HVAC services including installation, repair, and maintenance of heating, ventilation, and air conditioning systems as well as servicing gas & electric boiler systems, and air duct cleaning.

How often should I have my HVAC system serviced?

Ideally, your HVAC system should be serviced twice a year—once before the cooling season and once before the heating season. At a minimum we recommend having your systems serviced every two years.

Common signs include unusual noises, inconsistent temperatures, increased energy bills, and poor air quality.

How can I improve the efficiency of my HVAC system?

Regular maintenance, changing filters, and using a programmable thermostat can enhance efficiency.
