Oleg was very prompt, professional and provided good value service for cleaning our mini split system and changing central AC filter. We will for sure hire them again.

We had Oleg out to give us a quote on AC and he was so helpful! He took plenty of time to answer all of my questions (which were a lot) and asked even more follow up questions about our usage and needs. He then came up with a plan for an AC system that fit our needs and wasn't as expensive as other companies who didn't really listen to our needs very much.

Frequently Asked Questions

High-efficiency comfort
What is HVAC?

HVAC is short for Heating, Ventilation and Air Conditioning. HVAC is most oftenused to depictthe whole heating and cooling system consisting of the duct work, air filters, humidification controls, and registers.

What regular maintenance do heating and air conditioning systems need?

The most important part of HVAC maintenance aspect is maintaining unrestricted air flows. Dust, dirt, and debris are an HVAC system’s worst enemies. Whether it’s an indoor or outdoor unit, you must keep all filters clean and heat exchangers and coils free of restrictions.

We recommend that your heating and cooling system be checked and serviced twice a year; ideally a spring and autumn tune-up. Also we recommend that you change your filter regularly, depending on the type of filter you have. This alone can eliminate many of the most common problems that need fixing and can significantly reduce the likelihood of a serious breakdown.

How do I know if I have an existing warranty on my furnace, air conditioner or HVAC system?

Locatethe label on the outer surface of the equipment for a manufacture date. If the equipment is less than five years old it may have a warranty, but also may not based on the model. Warranty terms and conditions change by manufacturer and the installing company. Accord Air can verify the warranty status of your heating and cooling system via Get Warranty form.
