Can I add refrigerant to my AC myself?
Thermostat not working — how to diagnose
A non‑responsive thermostat can be a simple settings or battery issue—or a sign of wiring, low‑voltage, or equipment faults. This guide explains safe checks you can do in minutes, how to confirm system type and heat‑pump O/B settings, what Wi‑Fi dropouts mean, and when problems are actually in the HVAC system, not the thermostat. It also highlights coverage considerations many insurers require. Read the full guide below.
Why does my AC turn on and off frequently (short cycling causes)
If your air conditioner turns on and off every few minutes, it’s short cycling. Common triggers include airflow restrictions (dirty filters, blocked returns), thermostat placement or settings, a clogged condensate drain, or deeper faults like low refrigerant, oversized equipment, electrical component failure, or duct design issues. Some checks are safe to do, but many involve refrigeration and electrical systems—read the full guide for details.
Best AC Systems for Hot Climate
Best AC Systems for Hot ClimateRelentless summer heat puts unique stress on cooling equipment. In a hot climate, the best AC systems balance high efficiency, strong performance during peak temperatures, superior indoor air quality, and reliable durability. Below we explain the top system types, wha…
How Ocean Air and Salt Corrosion Affect AC Near the Coast
Why salt air is hard on ACOcean air carries fine salt aerosols that stay humid, conductive, and reactive. When these particles settle on an AC condensing unit, coils, and electrical parts, they create a thin saline film. That film pulls moisture from the air, accelerates oxidation, and triggers gal…
Do I need anti-corrosion coating on my outdoor AC unit?
Do I need anti-corrosion coating on my outdoor AC unit?Short answer: if you live near the coast, close to heavy traffic or industry, or you have a pool or irrigation spraying your condenser, an anti-corrosion coating on the outdoor AC unit can extend service life and help keep efficiency steady. In…
How Extreme Heat Affects AC Performance
Why ACs struggle in extreme heatWhen a heat wave pushes outdoor temperatures to extremes, air conditioners face physics that work against them. Your system must move heat from inside your home to hotter outdoor air. As the ambient temperature rises, the temperature difference across the condenser s…
