"Really fast and professional service when our HVAC broke in the peak of summer. Had it up and running in almost no time. My advice to first time homeowners like me in these cases is to always make sure you know what repairs and actions are being done. It'll help in regards to money."

"One of my AC compressors was not starting correctly every time. If it did start, it would run fine, but on hot days, when it would cycle frequently, (i.e. cool to target temp, stop, temp would heat up, thermostat would send signal to restart, and eventually the compressor would not restart). I don't remember the exact explanation, but I think there's a small fan linked to the capacitor. The fan provides some cooling to the capacitor which is stressed at startup time. Eventually the capacitor burned out because it wasn't getting its appropriate fan/cooling. First, this is a pretty specific problem. I'm fairly technical myself, and my father can fix anything. We had isolated the issue to the capacitor, but could figure out why it had failed. This is a large home and the large capacitor, so it really was a job for a professional -- capacitors offer plenty of opportunities to electrocute yourself pretty severely if your a "do-it-yourselfer." The No-Frost tech diagnosed the problem within a few minutes and explained it in detail. I called my old man to see what he thought, and confirmed that would definitely explain the problem. Second, the appropriate replacement part was an all-in-one capacitor/fan combo part specifically made by the vendor. Because my unit was a larger-than-typical unit AND these guys rushed out pretty much same day (or next morning -- I think it was a Friday going into a 95 degree weekend). The tech didn't have that exact part on his truck. He gave me two options, he had the same size capacitor and fan unit separately, so he could merge those together and get the unit functioning right then and there, or he could order the part and come back some time the following week -- he called the warehouse and they didn't have it in stock (my compressor is large and 10-years old). Given the weather, and everything else, I had him build the setup I needed, took him about 20 minutes to link the fan and capacitor together and the AC unit was humming along again shortly thereafter. I loved that he took the time to explain the problem in detail. He could tell i was "tinkerer," yet he was very politely patient with my ignorance (I had no idea the capacitor required its own cooling). I loved that he gave me the choice on waiting for the vendor's "officially sanctioned" part or just getting the unit working, and that he took the time to explain why this wasn't a risky workaround. I gave him a nice tip and emailed my neighborhood HOA email group the contact details as a reliable, trustworthy and well-priced service provider who will always go the extra mile for the customer. These guys fixed my furnace a year earlier when I nearly burned my house down by not paying attention to my intake... Would and have definitely recommend these folks for any HVAC needs."

"Victory HVAC installed 2 mini splits for me. Great communication, they showed up when they said they would, the job was completed in one day. They worked with me regarding placement as well as advice what brand to buy. Excellent service, reasonable price, they cleaned up when done and were very easy to work with. Yossi is extremely knowledgeable about all things HVAC. Super nice guy to boot. I will definitely use Victory HVAC for all my HVAC needs in the future. 5+ stars"

"I couldn?t be happier with the experience. Graham Solution handled the entire installation from start to finish, and the quality of the work was outstanding. He was professional, knowledgeable, punctual, and paid close attention to every detail. The installation was completed efficiently, everything was left clean when the job was finished, and the system works perfectly. It?s hard to find someone who takes this much pride in their work, and it definitely shows. I highly recommend him to anyone looking for reliable, high-quality HVAC installation. Excellent workmanship and great customer service from start to finish!"

"I called Carroll Mechanical for an estimate on a new high efficiency heat pump system. I met with a member of their team that clearly explained everything and helped to design a solution that worked for my family at a fair price. The install team arrived on time, they were very polished, and did a technically excellent job. The system is working really well and the whole family is comfortable! Couldn’t have asked for more - I’ll be using Carroll Mechanical as my go to HVAC contractor from here on out."

Heating and Air Conditioning questions, answered by experts

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.

If left untreated, a frozen AC unit can lead to costly damage, especially to the compressor and evaporator coils. When ice forms on the evaporator coils, they become brittle and more susceptible to breaking. Plus, a freeze makes your AC system much less efficient, which means it's wasting energy and costing you more in your monthly energy bills.

The simplest indicator is how long it’s been since your last tune-up. You should schedule an annual AC tune-up each spring. Beyond that, there are multiple signs that your AC needs a quick check by a professional. These issues include higher-than-average energy bills, decreased air flow from vents, higher indoor temperatures, and an air conditioning unit that stays on all the time or frequently turns on and off.

An AC drip pan may stop draining if there’s a clog where the drip pan connects to the drain line. Clogs can form from a lack of cleaning or from rust or corrosion buildup. Cleaning the drip pan at least once per month lowers the chances of debris clogging the drain line.

The cost to replace an AC unit averages around $5,900, with a typical range between $3,900 and $8,020. The final price depends on several factors, including the type and size of the air conditioner, its efficiency rating, your geographic region, and labor costs for installation. Smaller units like portable and window ACs are much less expensive, costing between $90 and $550, compared to central or ductless systems. If your current unit is less than 10 years old, repairing it may be more cost-effective than a full replacement.
