"So happy I worked with Magna for my issue! They came within 45 minutes of me posting on Angie's List... that has to be some kind of record. They diagnosed the issue quickly, clearly communicated what was needed and what the cost would be, and I moved forward with it. My AC was back up and running within an hour. Highly recommend! I've saved Magna Tech's phone number in my contacts and they will be the first company I call every time I have an HVAC issue."

"I recently hired AMJAIR LLC for HVAC installation and maintenance at my home, and the experience was highly professional from start to finish. Their team arrived on time, fully equipped, and took the time to assess my system before providing a clear explanation of the recommended service. The technicians were knowledgeable, courteous, and attentive to detail, ensuring that all equipment was installed correctly and functioning efficiently. Communication throughout the process was excellent, with updates on timing and cost provided upfront?there were no surprises. After the service, they conducted a thorough system check and offered practical tips for maintenance, which was a nice touch.

"Dominion Services replaced my 30-year old HVAC system (the outside compressor, and the inside air handler) with a modern one having a 50% increased efficiency rating. The quality of their work is high (four friendly employees with more than 100+ years' combined experience were involved) and have good flexibility to adjust to my work schedule. They easily adapted the new system to the existing hook-ups, and were flexible in their selection among alternate, reliable replacement HVAC systems. The replacement cost was well within the range of the national average. I recommend contacting Dominion Services for insight into any HVAC issue."

Heating and Air Conditioning questions, answered by experts

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.

HVAC pros recommend that you replace your AC filter every one to three months to maintain optimal indoor air quality and ensure your HVAC system operates efficiently. However, factors such as filter type, household size, and environmental conditions may influence the frequency of replacement. Regular filter changes help prevent debris buildup, maintain airflow, and prolong the life span of your air conditioning unit.

You will only need to refill your AC with refrigerant if it has a leak. Otherwise, a modern, well-maintained AC will most likely never need a recharge. You may notice a leak in an older system if your bills are higher, you hear a hissing sound, or if the air is blowing out hot.

No, you should not run an air conditioner with a Freon leak. If you think your AC unit is leaking refrigerant, shut it off immediately. When you keep using a leaky air conditioner, it could damage the unit and release more refrigerant. After turning off the AC, have an HVAC pro come take a look at the unit.

ACs don't run on water. They're not connected to drain pipes or any part of your plumbing system. However, they need refrigerant to run. Refrigerant is a gas or liquid that has a low boiling point and absorbs the heat in your home. ACs need this in order to be functional and cool your home. If you suspect your AC is low on refrigerant, you need to contact a licensed HVAC professional. Refrigerant is a dangerous chemical that requires specialized training and permits to work with.
