How do I know if I need your services?
If you notice leaks, water backing up, high utility bills, strange noises, or uneven heating or cooling, it’s time to give us a call.Â
Why is my AC running but not cooling?
Your AC has several components that operate independently; if the evaporator coils freeze or something compromises a heat exchanger, you’ll get air, but it won’t be cool. If the blower breaks, you’ll have cool refrigerant in place but no air blowing it out.
How often should I schedule HVAC maintenance?
As a general rule, you should have your home’s HVAC system inspected and serviced at least once a year. Twice a year (once for heating and once for cooling) would be ideal.
What are the signs that I need to replace my HVAC system?
Frequent breakdowns, rising energy bills, and fluctuating indoor temperatures are all strong signs that it’s time for an HVAC system replacement.
How can I improve my home's indoor air quality?
Keep the house well-ventilated by opening the windows and using fans. You can also use air purification devices, and avoid smoking or using products that contain volatile organic compounds (VOCs).
What should I do if I have a clogged drain?
Try using a plunger or a chemical drain cleaner. If that doesn’t work, it’s best to call a professional plumber.
