Dependable Service When You Need It Most

How Can We Help You?

Heating & Cooling Expertise You Can Count On

Heating and cooling problems can lead to big expenses long term. Rather than wait to see if a problem will go away on its own, contact us. What many homeowners don’t realize is that HVAC issues often decrease efficiency. As the problem worsens, energy consumption will rise, causing you to spend a lot more on electricity or fuel.

Some of the warning signs you should watch for include:

  • Weak airflow
  • Unusual noises
  • Unpleasant smells
  • Warm or cold spots
  • Short- or long-cycling

Is It Time for a New HVAC System?

If your heating and cooling systems are getting old, it’s an excellent time to consider replacement. Modern systems are notably more efficient than those made 10 to 15 years ago. Your older system has likely diminished in efficiency over the years as well.

Is Your Water Heater Costing You Too Much?

A common mistake is not scheduling water heater maintenance. Many homeowners take a break-fix approach to their water heaters. That approach shortens equipment lifespan and costs you more in repairs. During an annual appointment, we’ll flush your tank of all sediment and limescale. We’ll also check other important aspects, including:

  • Insulation
  • Thermostat
  • Sacrificial anode rod
  • Heat exchangers and elements
  • Temperature and pressure relief valve
  • Combustion and ignition systems

Tankless Is an Option

Tankless water heaters are among the hottest trends in home HVAC systems. The industry also calls these on-demand and instantaneous water heaters. A core difference between them and traditional systems is that they don’t store hot water in a tank. Instead, they heat the water when you request it. One advantage to this approach is that you have a virtually endless supply of hot water. The other advantage is better efficiency. There’s no energy wasted maintaining a hot water supply, which means you’ll spend less on a daily basis.

Sizing a tankless system can be tricky, but our experts can help you with it. It comes down to your household’s peak hot water demand, and we’ll account for factors like temperature rise. If you have a large house, we can help you consider features like a recirculating pump. A pump will help avoid common issues, such as long hot water delays and the cold-water sandwich effect.
