"Working with Connelly Heating and Air Conditioning was a terrific experience. My mother had her furnace crack and become disabled right before the week of Christmas. Shannon was terrific to work with both on understanding that in the middle of December she could not go without heat, and that funds were limited. He took the time to find us a great replacement and even installed on the weekend to prevent my mother from having to stay in the cold for more than a day. Installation was incredibly quick and done well within our budget. I would recommend Connelly Heat and Air Conditioning to everyone as Shannon is terrific to work with and is there to help. Well worth more than 5 stars and will be the only person I call whenever I have issues with Heating or Air Conditioning."

"The technician Adam couldn't have been more professional and helpful. He arrived on time and was very courteous. He quickly was able to assess the problem and repair it. I'd recommend One Hour Heating and Air Conditioning to anyone looking to install or repair their HVAC system."

"H L Bowman is by far one of the best service companies that I have dealt with. I got a call that the technician was on the way to my house. George showed up and got right to work. Found my problem and explained to me the best way to fix my issue. They did not try to sell me on any pricier fixes. George showed me what he could offer and explained what would be my best option. He was knowledgeable, informative, and explained everything so that I would understand what was going on. I am definitely going to be using them for all my heating and air conditioning needs. Top notch company. Would recommend to anyone needing this kind of help."

"I would highly recommend Prime Home HVAC. Our air conditioner was out for an entire weekend. I called Nathan on Monday, by Tuesday we had relief!! Nathan and his staff were professional and paid attention to detail. The price was fair and they made it easy. I love that they are a family-owned business. You will not be disappointed."

"These guys are the best. we moved into a new house back in June and had the hot water heater die after a few weeks. Frank was out the next day with a new hot water heater, at a excellent price. Both my wife and I were extremely happy with the work done, the price we were given and the customer service we got. Since then we have had two other 'emergencies' (air conditioner/leaky pipe in bathroom) and these guys came out right away and fixed the problems at excellent prices. Each time we had them at our house, they were very detailed about what the problem was and how they were going to fix it. Our HVAC is 25 years old and on it last legs. We've already asked Frank about it, and as soon as we are able to, we'll be calling Old Skool for our new one."

"Tash has done a great job! When I bought my house A/C unit stopped working. I searched for a local heating and air conditioner team. He was available same day, came out to check my unit and gave me reasonable quote for entire high efficiency furnace and A/C unit. I can say that he is well educated and knew what he was doing. Unit was ordered and installed with no issue. I highly recommend ATD Tech for Heating and air conditioning needs."

"Will Stahl from Stahl Mechanical called me the same day that I submitted my request for a pro. He came to my home for an estimate a few days later. He was knowledgeable about AC and electric, educating my husband and I regarding the different systems available, cost and efficiency. He and his 2 guys arrived the following week on time and finished the job in less time than estimated. Will was skillful, clean, respectful and friendly. He was genuinely concerned with the quality of his work and assisted us in setting the smart thermostat and returned upon request at no extra charge to adjust the vents to balance the air flow in all the upstairs bedrooms. I would highly recommend him to others and have given his card out to friends and family already."

FAQs for air conditioning projects in Mount Joy, PA

A standard blower door test takes between 30 minutes and one hour to complete. The process involves setting up specialized equipment in your doorway, running the fan to create pressure differences, and taking measurements throughout your home. Additional services like thermal imaging or detailed leak detection will extend this timeframe. The technician will also spend time explaining the results and making recommendations based on their findings.

Preparation involves turning off all combustion appliances, such as gas furnaces and water heaters, for safety. Secure all exterior doors and windows, but leave interior doors open to allow airflow throughout the house. Close fireplace dampers and cover any ashes to prevent them from being drawn into living spaces. Clear access to potential inspection areas like attics and crawlspaces, and inform everyone in the household about the test to prevent accidental door openings during the process.

Older homes often benefit most from blower door testing because they have more air leakage points than newer construction. The test can pinpoint specific areas where relatively inexpensive improvements will yield significant energy savings. 

Many homeowners of vintage properties report noticeable reductions in drafts and more consistent indoor temperatures after addressing issues identified during testing. The potential utility savings often recover the testing cost within a reasonable timeframe.

New construction must meet increasingly stringent energy codes that specify maximum allowable air leakage rates. Meeting these standards requires careful attention to air sealing details during construction. 

Success depends largely on properly installing air barriers, thoroughly sealing around penetrations, and quality control throughout the building process. While achieving code compliance is challenging, builders who implement systematic air sealing protocols succeed in meeting required standards.

It's best to schedule a follow-up test after completing all recommended air sealing and insulation work. This allows you to verify the effectiveness of your improvements as a complete package. Allow sufficient time for all sealing materials to cure properly—often a few weeks after completion. The verification test provides documentation of your home's improved performance and confirms you've addressed the issues identified in the initial assessment.
