"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 contacted Sean to repair my aging HVAC system. Although I have very little knowledge of HVAC, Sean was able to identify, explain, and plan the maintenance of my current system in language I understood and that seemed reasonable. Sean was very responsive via text during our scheduling and I'm happy with the expert level of detail he showed during inspection. I would highly recommend working with him or his team. Update: Sean came back out to resolve my filtration issues and also fixed some other problems that he noticed in the process without increasing the negotiated price. Again, Iâ m extremely satisfied with the work heâ s done and would recommend him for your HVAC needs."

"From not having a water supply for my whole home bypass humidifier, to having a repaired, new water supply line and instant winter comfort. All in less than two hours. Thanks Edmond and team for getting me taken care of right after I arrived home from work. Wealth of knowledge, too, about HVACs warranties, and other good general advice for first-time homeowners like myself! Glad to have signed-up tonight as a member - eligible for discounts tonight and future maintenance services. Highly recommend!"

"We got five different work proposals for our HVAC replacement. The person who came to our house was very technically knowledgable. He gave us his cell phone number and gave us plenty of his time answering our questions. I think this contractor would have done an excellent job at a good price."

"Customer service was communicative but not pushy. The technician, Nelson, was skilled, prompt, knowledgeable and above all else honest. I highly recommend this company and will certainly be contacting them in the future for all of our HVAC repairs and for our system replacement when the time comes."

Heating and Air Conditioning questions, answered by experts

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.

The general rule of thumb for figuring out how much AC tonnage you need in your home is that for every 500 to 600 square feet of space you need to cool, you’ll need one ton of AC cooling power. So, a 1,000-square-foot home will need 2 tons of AC power. 

Yes, HVAC zoning is generally considered worth the investment by both experts and homeowners. Zoned systems offer significant benefits in convenience, efficiency, and comfort by allowing you to set different temperatures for various rooms or 'zones' in your house. This ability to heat and cool only the spaces you're using leads to energy savings and lower utility bills. Zoned systems are especially effective in multi-level homes that experience temperature fluctuations, but even smaller homes can benefit from the ability to adjust temperatures more quickly. While the up-front installation cost can be high, many find it's a worthwhile long-term investment, particularly for those who plan to stay in their home for a while.

There are plenty of different not-so-great sounds to hear from your air conditioning unit, like squealing, grinding, water running, excessive gurgling, banging, and clanking. Each of these sounds can indicate a different malfunction with your unit, so it’s important to have a professional assess the problem before it gets worse.

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.
