We've used All Hours Air for two years for our now 18-year-old builder system. Their employees are always knowledgeable and helpful. They do a good job of explaining how our HVAC systems are holding up, discussing needed repairs and potential preventative maintenance. They also discuss whether or not it makes sense to invest in work on such an old system. Today Omar looked at our A/C system and mentioned that proactively replacing it during shoulder season (too late for that for this summer!) should cost less. He also told us that when we do replace it, we can save money by replacing the aging furnace at the same time. As a bonus, he took a look at the ductwork then explained why one room in the house doesn't seem to get as warm/cold as it should and suggested several adjustments, most of which did not involve any business for All Hours Air.
