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. 

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. 

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.

Had our power lines to the house taken down during a big storm, the folks at Haller were great at getting out quickly to check out the damage and give us an estimate to repair. We put a down-payment down to reserve service, ended up not needing them, and they promptly refunded our payment with zero fuss. Good experience, I recommend them
Highly recommended. On time, courteous and friendly! Carl was an excellent Hvac mechanic. A+++

John was very thorough and informative.
From Haller doing a routine check on my HVAC and noticing the the water heater leaking to the estimate to scheduling the replacement… then having to change the appointment because of leaving for a vacation…. Courtesy, professional, and the Plummer that did the job Shane was seriously great. I’m thankful.
The service was extraordinary. My service person was polite, informative and customer centric. This person is the type of person you want engaging with people. I also learned some good ac and furnace tips. I give Shane 5 stars….out of 5.
Nate was very nice to work with and very professional.
Garage toilet replacement.
Opted to provide own fixture and Haller requested for install. Mark Habbershon did a great job in removal, prep work, install, test & cleanup. . Confirmed improved trap dimensions for the new unit and much less likely to clog like old toilet with narrower trap. Very friendly and eager to do a quality job! Bravo Mark!!
Repair man was amazing nice and kind , unfortunately it was on the 4th of July and the rates were a lot higher ! But the repair man was great would highly recommend
Excellent experience with Shane Keifer on water heater installation. In addition a shout out to Amanda for helping get us booked in a very timely and friendly manner.
Christopher is wonderful and came out quickly . He is very professional and friendly. He took care of my central air and resealed the unit in the house. Closed the vents that are not being used to keep the cold air where I needed it. I would ask for Christoper the next time I had an issue.
Haller is best.
The technician, Adam, was excellent. He explained what the problems were, and showed me the problems on my outdoor fan. He was very patient and polite. I am hard of hearing, so he spoke louder. He fixed everything, and thought of solutions that had not been mentioned to me before – like using a 2" filter instead of a 1" filter to possibly cut down on filter changes (since I cannot change them myself). He also explained how the $24/month plan worked, and set me up for that when I decided to go with it. He answered all my questions. Adam is an excellent Haller employee.
Prompt competent, courteous service
Tech Nevin top notch w/ customer service. Extremely thorough.
Adam B was really amazing to have service my AC unit. He explained things thoroughly and completed everything in a timely fashion. Future services will request him.
Excellent service
Service tech, Phil R. arrived as scheduled, diagnosed the problem quickly and replaced the part on the spot. Thank you Phil for your professionalism and your kind, personable service.
He did an excellent job. 👏 He is very friendly and kind.
My air conditioner was repaired by Neffsville, but it failed again in just over a month. When it stopped working, I was told it would be four days before they could come back out (it’s 101 degree outside!).

I called Haller Enterprises instead, and they had a technician at my home within 24 hours. Jesse B. was knowledgeable, professional, and took the time to explain the issue and the repair. He diagnosed the problem quickly and completed the repair efficiently.

The difference in responsiveness and overall service was night and day. Based on my experience, I highly recommend Haller Enterprises for your HVAC needs. Thank you, Jesse, and the Haller team, for taking great care of us!
Adam B. came out on an extremely hot day and got the air fixed up and running well as soon as they got my call. He was very polite and friendly and explained everything he needed to do. I would highly recommend the company.
Very professional and tells you exactly what is going on. Highly recommend.
