What You Get With Professional Service

When your HVAC system works properly, you stop thinking about it. That’s exactly what you want.

You get consistent temperatures throughout your home, whether it’s January or July. Your energy bills stay predictable instead of spiking because of an inefficient system working overtime.

Most importantly, you avoid those middle-of-the-night emergencies when your heating system decides to quit during a snowstorm. Professional maintenance and quality repairs mean your system runs reliably when you need it most, and you’re not scrambling to find help during the worst possible moments.

We provide emergency HVAC service throughout Norfolk County and prioritize urgent calls, especially during extreme weather conditions. Response times depend on current demand and weather conditions, but we understand that heating failures in winter and cooling failures in summer can’t wait. When you call for emergency service, we’ll give you an honest timeframe and keep you updated if anything changes. Our goal is to get your system running again as quickly as possible while doing the work correctly.
This depends on several factors: the age of your system, the cost of repairs, and how efficiently it’s running. Generally, if your system is over 15 years old and needs major repairs, replacement might make more sense financially. We’ll assess your specific situation and give you honest recommendations based on repair costs versus replacement benefits. Sometimes a repair makes perfect sense, and sometimes investing in a new system will save you money long-term through better efficiency and fewer future repairs.
Our maintenance service includes a comprehensive inspection of your entire HVAC system, cleaning of key components, filter replacement, and testing of all safety controls. We check refrigerant levels, inspect electrical connections, test thermostat operation, and look for any signs of wear that could lead to future problems. Through our Dempsey Comfort Club, members get priority scheduling for these maintenance visits and discounts on repairs. Regular maintenance helps prevent unexpected breakdowns and keeps your system running efficiently.
Yes, we work on all major HVAC brands and models. Our technicians have experience with the heating and cooling systems commonly found in Norfolk County homes, from older established brands to newer high-efficiency models. We keep a wide range of parts in stock and can source components for most systems quickly. Whether you have a traditional furnace and central air setup or a heat pump system, we have the expertise to diagnose and repair it properly.
Several signs indicate efficiency problems: higher than normal energy bills, uneven temperatures throughout your home, the system running constantly without reaching the set temperature, or frequent cycling on and off. Strange noises, unusual odors, or poor air quality can also signal efficiency issues. During our diagnostic service, we test system performance and can show you exactly how efficiently your system is operating. We’ll explain what improvements would make the biggest difference in your comfort and energy costs.
First, check your thermostat settings and make sure it’s set to heat mode at the right temperature. Check that your circuit breaker hasn’t tripped and that your furnace switch is on. Make sure your air filter isn’t completely clogged, as this can cause safety shutoffs. If these basic checks don’t solve the problem, it’s time to call for professional service. Don’t attempt to troubleshoot gas connections or electrical components yourself – these require professional expertise to diagnose and repair safely.
