HVAC Services

Our heating and air experts encourage seasonal heating and cooling maintenance. Schedule a cooling tune-up in the spring and a heating tune-up in the fall. Most heating and air conditioning warranties require annual maintenance. This approach will lower your utility costs. It will also help prevent common repair issues.

Ready to revamp your HVAC? Trust our services:

  • Indoor air quality solutions
  • Oil-to-gas and electric-to-gas conversions
  • Heating, cooling, maintenance, and repairs
  • Indoor and outdoor lighting installation and repair
  • Heating and cooling installations and replacements

If you have an older heating and cooling system, we offer many energy-efficient upgrade options. That includes high-efficiency central and ductless ACs. For households with furnaces and boilers, we recommend condensing systems. These models can improve fuel usage by 10% or more by reducing heat losses associated with flues.

Our team can also convert your home to either a standalone or dual-fuel heat pump. Geothermal and high-efficiency air-source heat pumps can meet your year-round comfort needs. Hybrid systems utilize a mid-efficiency heat pump for both cooling and most heating purposes. They also have a fuel-burning furnace for auxiliary heat.

Plumbing Services

Hot water can account for nearly 20% of your household’s annual energy budget. Any steps you take to reduce consumption can cut your yearly costs. Our plumbing company recommends annual maintenance for your water heater.ย 

That includes flushing tank water heaters and descaling on-demand systems. If you have an old water heater, it’s an excellent time to upgrade. Even newer tank water heaters use less energy than models made 15 years ago. You can save even more in the long term by investing in a conversion to a tankless water heater.

Keep your pipes efficient! Use our plumbing services:

  • Leak detection and repair
  • Whole-home piping and repiping
  • Plumbing fixture installations and repairs
  • Drain clearing, drain cleaning, and hydro jetting
  • Water treatment system installation and service
  • Sump pump installation, maintenance, and repair
  • Trench and trenchless plumbing line repairs and replacements
  • Tank and tankless water heater installation and service

If you spend a lot on bottled water, consider hiring a plumber from our plumbing company to install a water purifier instead. Our plumber can install either a point-of-use or whole-house water purification system. 

A sediment filter will remove dirt, heavy metals, and other fine particles. Activated carbon will improve the smell and taste while adsorbing chemicals and gases. You can even opt for a UV lamp that neutralizes over 99% of bacteria, viruses, and other pathogens.

Electrical Services

Our electrical company helps bring older houses and buildings up to code through a range of electrical services. We can replace wiring and increase your amp coverage through a new electrical panel.ย 

Our team can install whole-home surge protection, as well as GFCI and AFCI protection. We can add circuits, install new lighting, upgrade outlets, and much more. Our electrician can transition your light bulbs to LEDs. We can upgrade outdoor lighting with small-scale solar panels and battery backup systems.

We also offer home improvements, including new electrical installations and whole-home backup generators. Every year, power outages result in financial losses for homeowners due to food spoilage and other damages. With a generator, you’ll enjoy the peace of mind that you’re protecting your family and home.

Stay powered with our electrical services:

  • Whole-home wiring and rewiring
  • Emergency repairs and replacements
  • Electrical panel installations and upgrades
  • Electrical inspections and code corrections
  • Standby generator installation, maintenance, and repair

An electrician can install an automatic transfer switch in your panel. The automatic transfer switch detects outages and starts the generator.

Excellent service. Very friendly and informative.
Aaron my service tech was very professional and knowledgeable. Appreciate the good service.
Great service, very timely and professional. Explained everything is easy detail.
My grandfather and I were helped by a man named Jesse Brubaker, who was sent out to check out our ac system in a rental house that my grandfather owns and I run. He was extremely polite and helpful in explaining everything going on and broke down all the options we had available. I had to call my grandfather before making any final decisions and my grandfather called him back to ask a few questions since I'm not as well versed in those systems. Jesse went beyond the typical expectancy of doing exactly what is required to do and no more, and instead took time to check things thoroughly which saved us money and time on fixing things that may not have ever been an issue! Thank you Jesse for being so helpful and earnest in our interaction! I'd hope he gets some kind of recognition from the company for being an outstanding employee and making a customer very happy with the service and the personal experience.

Nevin was my technician today and he was prompt and easy to talk to. He worked on my outdoor unit in the snow without a complaint and resolved my problem without being hateful to my wallet. The violent shaking of the unit was leading me to believe I needed a replacement. His honesty turned out to be a relatively easy fix and he was on his way in a timely manner. Thanks Nevin for your expertise and keeping the heat on!
