Five Things to Check Before You Call for Service

We’re only a phone call away, but here are five things you can check first to avoid the cost of a service call.
- Be sure your thermostat is set to the cool position. Most of the calls we receive at the beginning of cooling season are related to improper settings.
- Change your air filter if it’s dirty.
- Check the fuse box to see if a breaker has tripped or a fuse is blown.
- Close the equipment door if it’s open. This is a safety control.

- If your outside unit isn’t running, call us. It’s an indicator of a larger issue.

Frequently Asked Questions
Heating and Cooling
How can I tell if my heating or cooling system is functioning properly?
If your system is blowing warm or cool air at inconsistent temperatures, making strange noises, or if you notice unusual energy bills, these could be signs that something’s not working properly. We recommend scheduling an inspection if you notice any of these symptoms.
What is the average lifespan of a heating or cooling system?
Most heating and cooling systems last around 10-15 years, depending on the type and how well they’ve been maintained. Regular maintenance can extend the lifespan of your system.
How can I improve energy efficiency in my home or office?
Simple steps like changing filters regularly, installing a programmable thermostat, and sealing any gaps in your windows and doors can improve energy efficiency. We also offer energy audits to pinpoint other potential areas for improvement.
What should I do if my air conditioner is blowing warm air?
If your air conditioner is blowing warm air, the issue could be low refrigerant levels, a dirty air filter, or a malfunctioning compressor. Contact one of our technicians to diagnose and repair the problem.
Why is my furnace making strange noises?
Strange furnace noises could indicate a variety of issues, such as a loose part, a dirty filter, or an issue with the blower motor. If you hear unusual noises like rattling, banging, or squealing, it’s best to call us for a diagnostic check.
How do I know if my thermostat needs to be replaced or calibrated?
If your thermostat is not responding, or if the temperature it reads is consistently inaccurate, it might need calibration or replacement. A quick diagnostic from one of our experts can determine the problem.
Do you offer duct cleaning services?
Yes, we offer duct cleaning services to improve the airflow and overall efficiency of your HVAC system. Clean ducts also help reduce allergens and dust in your indoor air.
What are the signs that my heating system needs repair or replacement?
Signs to look for include uneven heating, strange noises, frequent breakdowns, and increasing energy bills. If your system is more than 10-15 years old, it might be more cost-effective to replace it than to repair it.
How often should I replace my HVAC filters?
We recommend replacing HVAC filters every 3-12 months, depending on your system type, filter material, and whether you have pets or allergies. Dirty filters can reduce efficiency and air quality.
Do you install and repair energy-efficient systems, like heat pumps or smart thermostats?
Yes, we specialize in energy-efficient systems like heat pumps and smart thermostats. These options help lower energy bills while maintaining comfort in your home or office.
