Emergency response times depend on the season and current service demand, but we prioritize urgent calls, especially during extreme weather conditions. Comfort Club members receive priority scheduling, which means faster response times when their systems fail. During peak seasons like mid-winter or summer heat waves, we expand our service hours to handle the increased demand. When you call with an emergency, we’ll give you a realistic timeframe and keep you updated if anything changes.
First, check your thermostat settings and make sure it’s set to heat mode with the temperature set higher than the current room temperature. Check your circuit breaker to see if it’s tripped, and make sure your furnace filter isn’t completely clogged. If these basics don’t solve the problem, it’s time to call for professional diagnosis. Heating systems have multiple safety switches and components that can prevent startup, and trying to troubleshoot beyond the basics can sometimes make the problem worse or create safety hazards.
Hot air from your AC usually means either your system is low on refrigerant due to a leak, or there’s an issue with the compressor or other cooling components. Sometimes it’s as simple as a dirty air filter restricting airflow, but more often it requires professional diagnosis. Refrigerant leaks need to be properly repaired and the system recharged with the correct amount of refrigerant. Running the system when it’s blowing hot air can damage the compressor, so it’s better to turn it off and call for service rather than letting it struggle.
Most HVAC systems benefit from professional maintenance twice a year – once before heating season and once before cooling season. This timing allows technicians to catch potential problems before they cause breakdowns during peak usage periods. Regular maintenance includes cleaning components, checking refrigerant levels, testing safety switches, and replacing filters. Systems that receive consistent maintenance typically last longer, run more efficiently, and have fewer unexpected breakdowns. Our Comfort Club makes this easy by scheduling these services automatically.
The decision usually comes down to the age of your system, the cost of repairs, and how efficiently it’s running. If your system is over 15 years old and needs major repairs costing more than half the price of replacement, replacement often makes more sense. Newer systems are significantly more energy efficient, which can reduce your monthly utility bills enough to offset the investment over time. However, if your system is relatively new and the repair is minor, fixing it is usually the right choice. A good contractor will explain both options honestly.
Yes, we service all major HVAC brands and models. Our technicians are trained to work on different manufacturers’ equipment, from older systems that are no longer made to the latest high-efficiency models. We keep common parts in stock for faster repairs, and can source parts for less common brands when needed. Whether you have a basic builder-grade system or a premium high-efficiency unit, we have the experience and tools to service it properly. We’ll also let you know if parts are becoming difficult to find for very old systems.
