Don’t Take Our Word For It

Very friendly and courteous. They came out the same day I called when my furnace quit working. Will definitely use them again if needed.Trustindex verifies that the original source of the review is Google.Paul Jones III called Exxel and asked them to look at my HVAC and give me a quote for a higher-capacity system. After checking the existing system and making sure that it was running fine, they advised me that I didn't need a new system installed and should run this one until it fails. They explained the range of options, but said that I really didn't need to spend that money. I was very impressed with their expertise and with their honesty. Exxel has my strongest recommendation. Good people; give them a call.Trustindex verifies that the original source of the review is Google.Dani NordanEXXEL is awesome! We had a 45 year OLD HVAC unit that EXXEL was able to do a simple tune up on shortly after we bought our house to get a few extra years out of it. This summer it finally bit the dust and we had EXXEL back out to replace it. We called them to check it out as it was leaking and they were able to come out same day to diagnose the problem. Once confirmed it was time to replace, we were on their books within a few days to have the work done. Bob was professional, punctual, honest, and informative. These guys are great! If you’re in the market for honest and fair HVAC services, these are your guys! We cannot recommend them enough 🙂Trustindex verifies that the original source of the review is Google.Kelsey FrancikOur upstairs AC unit went out the day we moved in. On top of moving stress, we now had to worry about getting someone in to fix/replace our unit at a reasonable price and quickly. Bob was recommended to us and I would extend that recommendation to others a thousand times over. He was able to come quickly, assess what needed to be done, and came back within a week to install a new unit. He and his partner Eric put it in in a couple of hours and I hardly knew they were here. Super professional, reasonable pricing, and great with noisy dogs 🙂 our second unit is 20+ years old and will undoubtedly be going out soon and Bob will be the first person we call!Trustindex verifies that the original source of the review is Google.ccp1657Expert mechanics, take great care to minimize disruption, clean up well.

Frequently Asked Questions
Strange Sounds
Clinks, pops, squeaks, or grinding. If you are hearing sounds that the unit never made before then it is time to call a professional. Even if the system still provides you with adequate temperature control, the sounds are an indication of am issue that lif left untreated will likely develop into a more expensive repair.
Water or Moisture
Look around the system. Is there lots of condensation or perhaps pools of water? This could be either a problem with the refrigerant which has started to leak or a problem with the drainage system. If you find these issues in your HVAC system, then maintenance or repairs should be the next step.
Odd smells
If you find that there is a pungent odor from your HVAC system, then there are usually two possibilities. 1) there is a problem with the wiring and some of the insulation has burnt away. 2) If the small is musty, then it means that there is pooled water in the system that has become a breeding ground for mold and mildew.
Inaccurate Thermostat
are different rooms different temperatures even though they are controlled by the same thermostat? This could be an issue with the thermostat itself for possibly the duct work.
The frequency of duct cleaning varies depending on the home and the preference of the homeowner. Typically, every 5 years is sufficient. There are a few things to consider when thinking about how often to have your ducts cleaned:
- Do you have pets that shed a high amount of hair and dander?
- Do you have smokers in your household?
- If anyone in your household has allergies, you may want to have your ducts cleaned more often.
- If you just moved into a home, it may be a good idea to have the ducts thoroughly cleaned.
- After a home remodeling, a heavy amount of dust and debris can be generated during a renovation.
A thorough duct cleaning will usually cost between $300 and $500, depending on the size of the home. Beware of companies offering cut-rate duct cleaning services. This is a well-known bait and switch tactic, and you could end up paying much more than you expected, or the company may not perform a proper duct cleaning. The Better Business Bureau has issued a warning about such services.
