"Kevin arrived today for the Spring Preventive Maintenance service on our HVAC system that we purchased a few years ago from Holtzople Heating & Air Conditioning. As always, we received an email and a phone call to let us know when the HVAC technician would be arriving. The Holtzople HVAC technicians are always very professional, clean, thorough, and polite and friendly. They are always willing to answer any questions we have, and their expertise and experience are evident in the excellent service they provide."

"I was looking for a company to replace a 27 yr old HVVAC system that was acquired with the purchase of our new home. I took the time to evaluate and entertain 5 companies with their associated estimates including Deans Heating and Air Conditioning. In my research I found that Deans HVAC had received 5 star reviews from every client for whom they had serviced. After speaking with Mike the owner I was very impressed as he listened to what I was looking for and shared exemplary knowledge on what my HVAC project needed. Mike took time to answer all of my questions in addition to providing the best and most fair estimate in comparison to the other companies I had spoken with. Mike was very thorough and took care to make sure everything was installed with precision and a personal attention to detail. Even though our project had its own unique challenges, Mike and his assistant worked with efficiency and finished in a timely manner. Working with Deans Heating and Air Conditioning was an awesome and rewarding decision as we are very pleased with the installation of our new HVAC system. I would highly recommend Deans HVAC to everyone looking for a knowledgeable, fair priced , caring, and professional company to address their HVAC needs ranging from general services to full HVAC replacement projects. Definitely a FIVE STAR company!!!!!"

"They were prompt and very professional. They kept us informed during the entire process of cleaning our ducts and dryer vent. They also installed an air scrubber and the total cost was several hundred dollars less than the quote we received from an HVAC company. The HVAC company told us we needed mold remediationâ ¦. DuctGurus found no mold. We received great service so we will be using and recommending this company in the future."

"Great experience Justin, Nate & Timothy were awesome. Very knowledgeable, professional & curious. Aside from the cleanliness they delivered an experience. I highly recommend HL bowman if you want rapid service on your HVAC. Pricing was reasonable in my opinion & financing is an option. Keep in mind when seeking quotes for your HVAC repair/ new install you must consider performance over equipment, that is if your want a good system that will have a good run/life span."

"We were Extremely Satisfied with the Quality of Workmanship and the Product we Decided to go with for HVAC Install... At the same time we had Central Air added, we were tired of window units... Plus, it is Less Expensive to have Both Installed Together!! We Have Really Noticed a Big Difference in how the Rooms in the House are Much More Evenly Heated and How Much More the Heat is Felt while Moving from Room to Room, From Floor to Ceiling!!! The House Has Never Felt So Good!!! A 10+ Star Rating in Our View from the Install and Service from Connelly Heating Air Conditioning!!! In Addition, We Saved over $1,000. with Connelly Heating Air with Bids from 3 other Companies!!! Thank You, Jean Tony S. in Manheim, PA."

"Great service started from calling to schedule the appointment! Received a text reminder before David arrived with his picture, which I thought was a really nice touch. Once he was here, Dave was thorough and spent a good amount of time explaining the maintenance mechanism on our HVAC system (we recently purchased our home and so I was interested in learning more about the UV and filtering system that was installed by the previous owner. Overall, A+. They will be my go to HVAC company for sure."

"

we had a leak problem and the tech came and looked over our equipment, fixed the problem and left. It cost us nothing and we have had their home heating service contracts for over 20 years.  They have NEVER ONCE not shown up or not helped and in the two furnace emergencies we had--they were here with in 1hr. 

We are very happy.

"Not only did they replace my old oil system with a heat pump, they replaced my entire AC system as well. Much more efficient, included new thermostats which are operated via mobile devices, and gave me peace of mind. Recommended an appropriate heating and AC system, replaced everything and did it in an efficient manner. Much more reasonably priced than all other quotes, prompt service & quick completion of the task. Didn't try to talk over my head about things that I wouldn't understand, explained it clearly and effectively. Highly recommend to anyone needing any type of heating or cooling repairs or replacements."

Heating and Air Conditioning questions, answered by experts

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

To reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Some units have a dedicated "reset" button; if yours does, press and hold it for three to five seconds. If your air conditioner doesn't have a reset button, or if you are resetting it after a power outage, leave the circuit breaker off for at least 30 minutes to allow the system to reset itself. Afterward, turn the power back on at the breaker, turn on the AC from the thermostat, and set it to "cool" to test the system.

When your HVAC technician mentions recharging your home AC unit, they’re referring to the process of topping off the unit with refrigerant, so the levels are properly maintained and pressurized. Normally, a properly functioning AC unit doesn’t need additional refrigerant, but AC units can develop leaks or other problems that decrease the amount of refrigerant needed.

A blocked return air vent can cause your HVAC system to work much harder and, therefore, less efficiently. The result is higher utility bills and poorer air quality. A blocked return air vent can also cause unpleasant dust, dander, and odors to linger in your home’s air.

Yes, but they don’t feel the same as an AC-cooled room. You’ll feel cool, moist air, opposite from an HVAC system that dries the air as it cools. Ventless units also have less tonnage than alternatives like ductless and central air, which means they aren’t as capable of quickly cooling large spaces or circulating cold air.
