Technicians assess your home’s square footage, layout, windows, doors, insulation, and numerous other factors to calculate its cooling demand and help you select the right AC model for your needs.
In addition to accurately sizing your air conditioner, technicians also consider its placement, refrigerant line and electrical connection configurations, manufacturer recommendations, and other important details. Once the installation is complete, the technician tests various AC components to make sure it is functional and calibrated properly.

Common Air Conditioner Issues
AC systems are complex and may experience a range of problems throughout their total lifespan. Understand these symptoms to know when your AC needs professional troubleshooting and repair.
AC won’t turn on
Tripped breakers, faulty wiring, and other problems may cause your system to activate its safety components and shut down. These problems prevent power from reaching the system and activating a cooling cycle.
Short cycling
Short cycling refers to air conditioners stopping and starting many times in one hour. Dirty coils, thermostat malfunctions, and numerous other problems cumulatively strain the system, potentially leading to high energy consumption, high electricity bills, and undue wear.
Insufficient or inconsistent cooling
Clogged air filters, blower motor failure, and other factors may restrict airflow and create hot and cold patches throughout your home.
Faulty thermostat
A faulty thermostat may lead to inaccurate temperature readings and prevent your AC from cooling efficiently. Whether your thermostat has damaged wiring, calibration problems, defective sensors, or simply needs new batteries, our technicians can help.
High energy bills
If your energy bills spike without a correlating increase in AC usage, your system may have underlying inefficiencies.
Strange noises
Rattling, grinding, buzzing, whistling, and other strange noises are often the result of mechanical issues or restricted airflow, which require prompt attention to prevent further damage.

Frequently Asked Questions
How can I prevent the need for AC repairs?
Regular professional maintenance is the best way to prevent unnecessary wear, damage, and repairs. Scheduling annual AC tune-ups, preferably in the spring before peak cooling season begins, helps keep your system running smoothly by addressing wear before it escalates into bigger problems.
Other ways to reduce wear on your system include:
- Using a programmable or smart thermostat.
- Sealing air leaks and improving home insulation.
- Installing or upgrading ductwork insulation.
- Replacing air filters regularly.
- Periodically cleaning the compressor unit.

AC maintenance doesn’t just prepare your system for the summer and ensure a comfortable indoor temperature — routine tune-ups also offer these key benefits:

- Reduced wear and breakdowns
- Prolonged system lifespan
- Warranty compliance
Are there financing options available for AC installations?
G&R Heating and Air offers flexible financing options with competitive rates and customized payment terms, allowing customers to get the AC services they need. Whether you need an AC repair or system replacement, financing means you don’t have to choose between compromising on cooling or straining your budget — instead, you can get essential services at an affordable price.
How long does it take to install a new AC system?
