I have been working with Haller for several years for my whole house generator. The techs have been super friendly and informative, which I really respect because I like to know how these things work! Very reasonable prices too! They were also the only service company that I was able to find to work on my generator, because everyone else didnโ€™t want to touch it since they โ€œdidnโ€™t install itโ€โ€ฆ I have no idea who installed mine because it came with the house and the previous owner didnโ€™t leave us that info. Haller has definitely been a life saver for my generator!
Complete HVAC system installation was done flawlessly and efficiently. Consultation and service was professional from the start to end.
Have only experienced fine dealings with everyone at Haller during the seamless process of replacing the old HVAC system and then with each seasonal maintenance check-up. Recently, Jeff performed the winter-to-summer maintenance work. He made this system simple and easy to understand for us, and we appreciate his patience and expertise. Highly recommend Haller Enterprises!

Frequently Asked Questions

What HVAC services does Haller provide?

We handle all types of heating and cooling work in Altoona, from emergency repairs to complete system installations and regular maintenance visits. Our technicians service furnaces, heat pumps, boilers, ductless mini splits, and central air systems to keep your home comfortable through Pennsylvania’s cold winters and humid summers. You need a quick fix or a full replacement, and we work on every major brand and system type.

How often should I schedule HVAC maintenance?

Your heating system should get professional maintenance once yearly, ideally before winter starts, and your cooling system needs the same attention before summer arrives. Regular tune-ups in Altoona catch small problems before they become expensive repairs, keep your equipment running efficiently through Pennsylvania’s temperature extremes, and help your system last longer. Most homeowners schedule heating maintenance in fall and cooling maintenance in spring to stay ahead of the seasons during which you need these systems most.

Do you offer 24/7 emergency HVAC services?

Yes, we provide 24/7 emergency HVAC services for urgent heating and cooling issues. If your system stops working during extreme Pennsylvania temperatures, we respond quickly to restore comfort and safety.

How do I know if I should repair or replace my HVAC system?

Age is the biggest factor. Heating and cooling systems in Altoona typically need replacement after 12 to 18 years, especially if you’re calling for repairs multiple times per year or noticing uneven temperatures throughout your home. Repair costs start adding up to half the price of a new system, or your energy bills keep climbing despite regular maintenance. Replacement usually makes more financial sense. We’ll assess your current equipment’s condition and efficiency to give you a straight answer about whether fixing it or upgrading will save you more money over the next few years.

Can a new HVAC system help lower my energy bills?

A modern, high-efficiency HVAC system can cut your energy bills substantially compared to older equipment. Today’s systems use advanced technology that extracts more heating and cooling from each dollar of energy, and properly sized for your Altoona home’s specific needs, they don’t work as hard to maintain comfortable temperatures. Smart thermostats add another layer of savings by learning your schedule and adjusting automatically, while professional installation makes sure the system operates at peak efficiency from day one.
