Heating, Cooling, and Plumbing Installations
Choosing a new system for your home is a big decision! We’re here to walk you through it. You’ll get clear explanations, straightforward recommendations, and clean, professional installation from our in-house team.
We install high-efficiency furnaces, central AC systems, mini splits, heat pumps, water heaters, and more. Whether you’re switching fuel types, upgrading an old system, or outfitting a newly built space, we make sure everything is set up to run smoothly from day one. No guessing, and no shortcuts.
HVAC Repairs Done Well the First Time
When something stops working, it helps to have a team you trust. We repair a wide range of heating and cooling systems, including boilers, furnaces, AC units, mini splits, and hot water heaters. Our vans are stocked with common parts, which means many issues can be fixed on the first visit.
We also make it a point to explain the problem in plain language. If we can fix your existing system safely and affordably, that’s what we’ll do. If it makes more sense to talk about replacement, we’ll help you understand the options. Either way, you stay in control of the decision.


Water Filtration For a Higher Quality of Life
Not all water issues are obvious, but over time, hard water and sediment buildup can cause problems for fixtures and appliances. If your tap water has an unpleasant taste or leaves spots on your dishes, a filtration system may be worth considering.
We install both point-of-use systems under sinks and whole-home units that treat water as it enters the house. After we test your water and learn what you’re dealing with, we’ll recommend a setup that actually makes sense for your home.
HVAC and Plumbing for New Homes and Renovations
If you’re working with a builder or planning a full remodel, we offer full mechanical support, including HVAC layout, ductwork, venting, gas lines, plumbing, and fixture installs. We coordinate closely with general contractors and homeowners to keep everything on track and avoid surprises.
We’ve worked on custom homes, multi-level renovations, and full mechanical upgrades where nothing was up to code. Our experience on both the HVAC and plumbing side means you don’t have to coordinate between multiple trades. You’ll have one team, one timeline, and one point of contact.
We’re comfortable reading blueprints, adapting to field conditions, and making smart decisions to avoid issues later. If you’re early in the planning process, we’re happy to consult before any framing or finish work begins.
What to Expect When You Call Us
People often call us after having a bad experience with another company—missed appointments, vague pricing, or work that didn’t last. That’s not how we operate.
When you call Reliant, we’ll talk through your concerns, answer questions honestly, and schedule a visit that works for you. Once we’re on-site, we protect your floors, explain what we’re doing, and walk you through next steps. You won’t be left wondering what was fixed or why something needs to be replaced.
Our quotes are detailed and practical. If we can offer a few options (like a short-term fix or a long-term upgrade) we’ll talk you through both. We don’t hide fees or surprise you with add-ons.
Choosing the Right System for Your Home
Every home is different, and the best heating or cooling setup depends on how you live and what you need. We help you weigh the pros and cons without pushing a particular brand or technology.
If you’re considering a ductless mini split or heat pump, we’ll show you what makes the most sense for your layout. These systems are efficient and allow for zone control, which helps lower energy use without sacrificing comfort. For homes with existing ductwork, we might recommend a high-efficiency furnace or central AC setup.
Water heaters come in a few types: tank, tankless, hybrid. We’ll help you figure out which model matches your usage and space. We also work with both gas and electric systems, and we stay up to date on rebate programs that may help offset installation costs.
Our go-to equipment includes trusted names Buderus, Viessmann, AO Smith, Bradford White, Bryant, Mitsubishi, Rinnai, American Standard, Trane, and others. Feel free to ask.
