He was on time,he let me know exactly what he was doing. He'd showed me what the problem was and what could happen. He was very thoughtful and informative and of course very friendly. Yes, I would recommend him to my home ๐Ÿก. That's why I like having Haller Enterprise for my home needs.
Carl is wonderful! Great job and really nice guy. Thank you April
Would like to give positive comment to Jessee and Austin- your two technicians who did a great job on problem-solving our AC unit recently
Ken was excellent including his explanations!
My service tech was very knowledgeable and did an excellent job explaining my system and the condition it is in. He was very professional and friendly.
Outstanding….best technician yet!
My AC service was top notch. I appreciate Haller's maintenance options, which provide me flexibility and affordability. Don H. did a great job on my system and is very knowledgeable on upkeep and improvements. Thanks!
Did a great job on our AC installation
We had annual maintenance performed on our air conditioning and then had to make a call later in the week for our garbage disposal. Both times our technicians, Brayden and Trenton, were polite, professional, on time, and efficient. Even the receptionist was on point with our issue, courteous, and a pleasure to speak with.

Each technician provided follow-up advice and key things to be watchful of. We are beyond pleased with the services Haller provides as well as their staff and technicians. The service fee is reasonable and the maintenance contract we have for our A/C is a cost saver.
Gabe from Haller Enterprises arrived promptly when scheduled. He listened carefully to my questions/concerns and then made an honest effort to find answers/solutions. Although no immediate resolution to the main issue was found, Gabe promised to continue his search on his own and contact me promptly when he had success.
I used Haller Enterprise to replace some plumbing and was very pleased.
Needed emergency service and they were there within a few hours. Great service. Friendly and efficient.
Brandon did a great job replacing a shower valve. He also cleaned up after the job was complete. We will definitely use Haller in the future.
Excellent Service. Pleasant technician!
Christopher is my maintenance tech who comes out twice a year. He does a great job and is always honest and clear. Appreciate his patience as I do have 3 dogs and he is always accomodating. Thanks!
My AC stopped working on a Saturday evening. The repairman was here in under an hour. The condensate pump had failed. He replaced it and was on his way in under 30 minutes. He asked management if the service call fee could be waived since the annual maintenance had recently been done and that lowered the bill by $200. This is a high character company with customer oriented employees. Five stars.
Nevin is top tier. Comes up with solutions and executes a plan like if it was his own home. Very dedicated for a successful outcome at a fair cost.
Haller diagnosed the issue with my whole-house water filtration system quickly. It was repaired quickly as well. Friendly service person who explained the issues and solution to me. I already had their service plan for one hvac system, so I converted to a whole home plan to cover the water and upstairs hvac as well.
Great service with great advice. I was very happy with my experience and maintenance.
Phil was awesome.
A technician by the name of Hunter came out to fix our air conditioning unit. He was very thorough and informative. He was able to diagnose the issue quickly and efficiently. We were very pleased with his service.
Fixed our heat pump. Nevin was professional and courteous.
They did a great job, were courteous, and explained everything they did and how it works. I recommend them.
Iโ€™ve been a long time customer, and they provided me with excellent service, and treated me fairly for a recent job. The tech was great as well, knowledgeable and quick. Very pleased overall
The HVAC technician, Mason , was extremely professional, polite, and knowledgeable. He fully explained each phase of the process for both of my units.
Friendly and quick service. Only dinged them 1 star because they charge a lot for R-410A coolant installed; too expensive.

Air Conditioning Installation FAQs

How do I know what size air conditioner my home needs in Yorklyn?

Your home’s square footage, insulation quality, existing ductwork, and room layout all factor into determining the right AC size for your Yorklyn property. An undersized unit will struggle during Pennsylvania’s humid summers. An oversized system cycles on and off too frequently, wasting energy and creating uneven temperatures. Our technicians conduct a thorough assessment of these variables during your consultation to match the system capacity to your home’s specific cooling needs.

How long does air conditioning installation take in Yorklyn?

A typical AC installation in Yorklyn takes one full day from start to finish. Projects involving ductwork changes or electrical upgrades can extend to two days, depending on your home’s specific requirements. We’ll give you an exact timeframe during your initial assessment so you know what to expect.

Do you offer financing for AC installation in Yorklyn?

Yes, we provide financing options that make AC installation in Yorklyn more affordable for homeowners. We also handle air conditioning installation in York County and surrounding areas. Our specialists explain each financing plan clearly so you can select what works best for your situation.

What’s the average lifespan of a new air conditioner in Yorklyn?

A properly installed air conditioning system typically provides 10 to 15 years of reliable service in Yorklyn with regular maintenance. Pennsylvania’s humid summers can be demanding on AC equipment. Annual tune-ups and filter changes become especially important for getting the full lifespan from your investment. Regular maintenance visits help catch small issues before they turn into major problems that could shorten your system’s life.

Is professional installation really that important in Yorklyn?

Professional air conditioning installation in Yorklyn makes all the difference between a system that works properly and one that causes problems from day one. Incorrect installation can void your warranty, reduce efficiency by 20-30%, and lead to premature breakdowns during Pennsylvania’s humid summers. Our certified technicians follow manufacturer specifications and local codes to get your system running right. This protects your investment and keeps your home comfortable during those hot summer months.
