"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."

"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."

"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."

"Woke to a chilly home stemming from a heat-pump issue. Posted my repair service need on Angi and within minutes, received a text and phone call from HOFFMAN MECHANICAL, who was able to come out same day and got my Lennox unit up and running again at a fair cost for both parts and the weekend/after hours service call fee. I would use them again without hesitation, and I am happy to highly recommend this company!"

"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."

"I can't say enough about the team at Old Skool HVAC. I learned of this organization from a close friend who had work done and recommended them. Frank is a great guy. On time, professional, knowledgeable, and his team is a reflection of this as well. They were always on time, on schedule, clean, and very personable. They finished our job a little early, and during the first heat wave just about week or two ago, our house never felt better. Great service, quality, and pricing. It's funny, with central AC, you never really know that it's hot out until you leave the house and come home. It's during this first transition that I realized how quiet and effective of a system that was installed. If you are looking for any form of HVAC work in your home of business, I'd recommend contacting this group of professionals."

Heating and Air Conditioning FAQs, answered by experts

A dirty AC filter can lower the efficiency of your system, so depending on how dirty it was, you may notice a temperature difference when you clean your filter. You can try other solutions if your AC isn’t blowing as cold as it used to. You can call in a local HVAC tech to make sure everything is running correctly, fix your air seal if it’s a window unit, and clean your coils.

When your HVAC system is loud, a few different causes are possible. If you have loose connections or bolts in the hardware, they can rattle as the system runs and vibrates. If you have an extremely dirty furnace filter, it could cause the system to generate noise. More commonly, an excessively loud HVAC system indicates a malfunction in the system. You may have a blower motor that is close to failing or a compressor that is breaking down. These issues require an immediate inspection.

A calculation method that your HVAC contractor will use to ensure your system does what it's supposed to is measuring duct output, or its CFM. The calculation requires knowing the cross-sectional area of the ductwork and determining the air speed past any given point within it.

Traditional central air conditioning systems require ductwork to circulate air throughout the home. Alternatively, you can add air conditioning with a mini-split ductless air conditioning system, which can be just as energy efficient as a central air conditioner. This type of system consists of two units–an outside unit that holds the compressor and condenser and an indoor unit that holds an air-handler. With multi-zone ductless systems, there are multiple indoor air handlers tied to a single outdoor compressor/condenser, allowing the system to cool multiple rooms.

Swamp coolers cost approximately 50 percent less to install than central air conditioners and cost less to run. Operation costs depend on the size of the unit and home, your climate, utility rates in your area, and the system’s efficiency. Swamp coolers use 15 to 35 percent less power than air conditioners.
